<div>-----------------------------------------------<br />
== Creating the Boundary Layer Attribute File==<br />
* To begin, we need a geometry model. It can be created using commercial softwares such as SolidWorks or NX and saved as *.x_t<br />
*Create a new directory, which will contain the new geometric model and boundary layer attribute file (BLattr.inp). Make a link to the geometric model: <br />
ln -s "model_name.x_t" geom.xmt_txt<br />
Now copy whichever BLattr.inp file you wish to start from to your working directory.<br />
<br />
*Each face of the geometric model needs specific mesh and boundary layer characteristics. This is the purpose of BLattr.inp. Open it by typing:<br />
vim BLattr.inp<br />
A vim command cheat sheet can be found at http://www.tuxfiles.org/linuxhelp/vimcheat.html<br />
* To create attributes for each model entity, two lines in the following format are being used. <br />
<entity dimension> <entity tag> <size type> <attribute type> <extra> <br />
<value or expression for mesh size on this entity><br />
* Note that a blank line between these two lines is not allowed.<br />
*The parameters in the first line, respectively are: <br />
- Entity dimension: This will be 2 if the BL is being specified on a face<br />
- Entity tag: You can find the entity tag using simapps<br />
- Size type on entity: 1 for absolute mesh size and 2 for relative mesh size<br />
- Attribute type on entity: <br />
0 just imposes the size on entity. '''<extra> field''' is NULL<br />
1 for entity with boundary layers. '''<extra> field''' is explained below.<br />
2 for periodic entity: In this case, '''<extra> field''' is followed with slave entity tag<br />
3 for refinement source. Specify entity dimension as -1 in this case. '''<extra> field''' is explained below.<br />
<br />
For Boundary layer: <br />
the <extra> field consists of (a) faceSide/useDir (BL orientation), (b) numEndEnts (==0, layers with fixed heigths), (c) firstLayerHeight, (d) totalHeight, <br />
(e) nLayers, (f) blMixed, (g) blBlends, (h) blPropagate and (i) edgeBLFaceTag (only if 2D BL on edge)<br />
<br />
*You can insert text by hitting the "a" or "i" keys. Hit escape to go back to visual mode<br />
*You can comment out lines or parts of lines by placing a # symbol before the text you want to comment out. This is useful for suppressing BL's and<br />
assigning names to the face numbers<br />
<br />
*To save and quit the changes you've made to BLattr.inp, get back to visual mode and type ":wq" and hit enter.<br />
<br />
== Creating an Initial Mesh==<br />
*FIRST, MAKE SURE YOU ARE CONNECTED TO ONE OF THE VIZ NODES AND NOT PORTAL0!! <br />
*To do this, type:<br />
"vglconnect viz001" or "vglonnect viz002". You should also type "top" to see who is currently working and that enough memory is available<br />
*cd back to your working directory and type<br />
/users/mrasquin/develop/Meshing/BLMesher/bin/x86_64_linux/BLMesher geom.xmt_txt geom_ver63.sms 2 1.0 BLattr.inp BLMesher.log<br />
or cp runBLMesher.sh (you can find it at /users/jema6380/runBLMesher.sh) into your working directory and type<br />
./runBLMesher.sh geom.xmt_txt geom_ver63.sms 2 1.0 BLattr.inp BLMesher.log<br />
*This creates geom_ver63.sms. If it aborts immediately, look at BLMesher.log to get a sense of where in BLattr.inp it failed.<br />
*'''''Note: if you plan on using phParAdapt later, then you are done creating an initial mesh. You should not trim and tetrahedronize the mesh before partitioning it with phParAdapt. See the page on using phParAdapt'''''.<br />
*Next, you need to convert geom_ver63.sms into geom_ver2.sms so that the BL can be trimmed later. cp runConvertSMSVersion.sh (see /users/jema6380) to your working directory and type:<br />
./runConvertSMSVersion.sh<br />
*Now you can trim the boundary layer:<br />
/users/mrasquin/develop/Meshing/BLTrim-2011-08-25/bin/x86_64_linux-icc/BLTrim-O geom.xmt_txt geom_ver2.sms 1 0 0 0 geom_test_bl.sms 2 1<br />
*Questions:<br />
Enter option [1/0] to write trimmed BL mesh: 1<br />
Enter output filename: geom-trimmed.sms<br />
Enter number of BL surfaces to be visualized: 0<br />
*Tetrahedronize the mesh:<br />
/users/chitak/develop/Meshing/tetrahedronizeBL-for-curve/bin/x86_64_linux-icc/tetrahedronizeBL-for-curve-O geom.xmt_txt geom-trimmed.sms geom-trimmed-tets.sms<br />
<br />
*'''''Alternatively, to save time you can mesh, trim, and tetrahedronize all in one fell swoop'''''. cp runBLMesher.sh, runConvertSMSVersion.sh, and runMeshAll.sh (see /users/jema6380) to your working directory. Run the command:<br />
./runMeshAll.sh geom.xmt_txt BLattr.inp<br />
<br />
*The trim process is important so that the mesh can be adapted later, but it's not necessary in order to run your case. <br />
<br />
*You can now view the trimmed, tetrahedronized mesh (geom-trimmed-tets.sms) using ThreeDViewer.</div>Jema6380https://fluid.colorado.edu/wiki/index.php?title=FaceProperty_Script&diff=394FaceProperty Script2013-07-20T20:13:14Z<p>Jema6380: </p>

<div>The purpose of this script is to automate the creation of a new BLattr.inp file for a new parasolid model. You need a previous model that is very nearly the same as the new model, with the exception of a few new changes. You also need the BLattr.inp corresponding to the previous model, and your new geometric model for which you want to create a new BLattr.inp<br />
<br />
*connect to either viz001 or viz002<br />
*cd to the working directory where your model is saved (i.e. for Boeing, it might be Open26_12jets). Copy the old geometric model to this directory and call it geom2_old.xmt_txt, and the old BLattr.inp. Also copy over the new geometric model and call it geom2_new.xmt_txt. Make sure you have saved the native parasolid model that was generated in spaceclaim from ThreeDViewer.<br />
<br />
*copy these files to the same working directory: <br />
/users/jema6380/Executables/MatchFaceID.m<br />
<br />
/users/jema6380/Executables/runMatchFaceID.sh<br />
<br />
/users/jema6380/Executables/SwitchAttribFileFaces.rb<br />
<br />
<br />
*open runMatchFaceID.sh with vim<br />
<br />
Notice that this script takes 3 arguments, specified at the top in the following order: the old model file, the new model file, and the old BLattr.inp<br />
<br />
Notice that this script runs a matlab file but doesn't open the matlab GUI. The statement /opt/matlab/R2013a/bin/matlab may need to be changed if the matlab is updated to a new version in the future - keep this in mind.<br />
*change "/users/jema6380/Models/TrapWing/FaceProperty_Debug/" to the full path of your working directory.<br />
<br />
*open MatchFaceID.m<br />
This script compares the minimum and maximum x,y,z coordinates of all vertices (6 pieces of information) for each face and will call faces a "match" if all 6 agree within a certain tolerance. There is a variable called "tol", which is currently set to 1e-5. Feel free to play around with this number, but 1e-5 has worked the best so far.<br />
*You need to change 3 paths in this file to your working directory, which are at the top: "/users/jema6380/Models/TrapWing/FaceProperty_Debug/", "/users/jema6380/Models/TrapWing/FaceProperty_Debug/", "/users/jema6380/Models/TrapWing/FaceProperty_Debug/".<br />
<br />
*run the following command:<br />
./runMatchFaceID.sh geom2_old.xmt_txt geom2_new.xmt_txt BLattr.inp<br />
<br />
It will take about a minute to generate the files "output" and "MatchFaceID.dat". "output" contains your new BLattr.inp, and it has all the same attributes as the old BLattr.inp - all it did was replace the old face ID's with new matching face ID's. In "output", every new face that was uniquely matched to the old model has a comment saying "#corrected" after the line. Every face that either was not matched at all or had multiple matches says "#Match not found" after the line.<br />
<br />
*Open the file MatchFaceID.dat<br />
This will tell you in detail which faces were matched, which faces were not uniquely matched (i.e. had duplicate matches), and which faces had no match at all. The left column lists faces from the old model, and the right column lists the corresponding match from the new model. You need to pay attention to the faces that had duplicates or were not matched at all and manually give these faces attributes.</div>Jema6380https://fluid.colorado.edu/wiki/index.php?title=FaceProperty_Script&diff=393FaceProperty Script2013-07-20T20:06:40Z<p>Jema6380: </p>

== Creating the Boundary Layer Attribute File==<br />
* To begin, we need a geometry model. It can be created using commercial softwares such as SolidWorks or NX and saved as *.x_t<br />
*Create a new directory, which will contain the new geometric model and boundary layer attribute file (BLattr.inp). Make a link to the geometric model: <br />
ln -s "model_name.x_t" geom.xmt_txt<br />
Now copy whichever BLattr.inp file you wish to start from to your working directory.<br />
<br />
*Each face of the geometric model needs specific mesh and boundary layer characteristics. This is the purpose of BLattr.inp. Open it by typing:<br />
vim BLattr.inp<br />
A vim command cheat sheet can be found at http://www.tuxfiles.org/linuxhelp/vimcheat.html<br />
* To create attributes for each model entity, two lines in the following format are being used. <br />
<entity dimension> <entity tag> <size type> <attribute type> <extra> <br />
<value or expression for mesh size on this entity><br />
* Note that a blank line between these two lines is not allowed.<br />
*The parameters in the first line, respectively are: <br />
- Entity dimension: This will be 2 if the BL is being specified on a face<br />
- Entity tag: You can find the entity tag using simapps<br />
- Size type on entity: 1 for absolute mesh size and 2 for relative mesh size<br />
- Attribute type on entity: <br />
0 just imposes the size on entity. '''<extra> field''' is NULL<br />
1 for entity with boundary layers. '''<extra> field''' is explained below.<br />
2 for periodic entity: In this case, '''<extra> field''' is followed with slave entity tag<br />
3 for refinement source. Specify entity dimension as -1 in this case. '''<extra> field''' is explained below.<br />
<br />
For Boundary layer: <br />
the <extra> field consists of (a) faceSide/useDir (BL orientation), (b) numEndEnts (==0, layers with fixed heigths), (c) firstLayerHeight, (d) totalHeight, <br />
(e) nLayers, (f) blMixed, (g) blBlends, (h) blPropagate and (i) edgeBLFaceTag (only if 2D BL on edge)<br />
<br />
*You can insert text by hitting the "a" or "i" keys. Hit escape to go back to visual mode<br />
*You can comment out lines or parts of lines by placing a # symbol before the text you want to comment out. This is useful for suppressing BL's and<br />
assigning names to the face numbers<br />
<br />
*To save and quit the changes you've made to BLattr.inp, get back to visual mode and type ":wq" and hit enter.<br />
<br />
== Creating an Initial Mesh==<br />
*FIRST, MAKE SURE YOU ARE CONNECTED TO ONE OF THE VIZ NODES AND NOT PORTAL0!! <br />
*To do this, type:<br />
"vglconnect viz001" or "vglonnect viz002". You should also type "top" to see who is currently working and that enough memory is available<br />
*cd back to your working directory and type<br />
/users/mrasquin/develop/Meshing/BLMesher/bin/x86_64_linux/BLMesher geom.xmt_txt geom_ver63.sms 2 1.0 BLattr.inp BLMesher.log<br />
or cp runBLMesher.sh (you can find it at /users/jema6380/runBLMesher.sh) into your working directory and type<br />
./runBLMesher.sh geom.xmt_txt geom_ver63.sms 2 1.0 BLattr.inp BLMesher.log<br />
*This creates geom_ver63.sms. If it aborts immediately, look at BLMesher.log to get a sense of where in BLattr.inp it failed.<br />
*'''''Note: if you plan on using phParAdapt later, then you are done creating an initial mesh. You should not trim and tetrahedronize the mesh before partitioning it with phParAdapt. See the page on using phParAdapt'''''.<br />
*Next, you need to convert geom_ver63.sms into geom_ver2.sms so that the BL can be trimmed later. cp runConvertSMSVersion.sh (see /users/jema6380) to your working directory and type:<br />
./runConvertSMSVersion.sh<br />
*Now you can trim the boundary layer:<br />
/users/mrasquin/develop/Meshing/BLTrim-2011-08-25/bin/x86_64_linux-icc/BLTrim-O geom.xmt_txt geom_ver2.sms 1 0 0 0 geom_test_bl.sms 2 1<br />
*Questions:<br />
Enter option [1/0] to write trimmed BL mesh: 1<br />
Enter output filename: geom-trimmed.sms<br />
Enter number of BL surfaces to be visualized: 0<br />
*Tetrahedronize the mesh:<br />
/users/chitak/develop/Meshing/tetrahedronizeBL-for-curve/bin/x86_64_linux-icc/tetrahedronizeBL-for-curve-O geom.xmt_txt geom-trimmed.sms geom-trimmed-tets.sms<br />
<br />
*'''''Alternatively, to save time you can mesh, trim, and tetrahedronize all in one fell swoop'''''. cp runBLMesher.sh, runConvertSMSVersion.sh, and runMeshAll.sh (see /users/jema6380) to your working directory. Run the command:<br />
./runMeshAll.sh geom.xmt_txt BLattr.inp<br />
<br />
*The trim process is important so that the mesh can be adapted later, but it's not necessary in order to run your case. <br />
<br />
*You can now view the trimmed, tetrahedronized mesh (geom-trimmed-tets.sms) using ThreeDViewer.<br />

==For Incompressible Flow==<br />
=== Inflow ===<br />
comp3: The name is arbitrary but should be set to something meaningful (i.e. Inflow). Click on the inflow face (which is the face which makes up the front of the wind tunnel) and go to Create -> comp3. Set vector magnitude to the free-stream velocity you want. Set the vector direction to the direction (i.e. if the free-stream velocity moves strictly along the x-axis, the direction would be [1 0 0]). Even if the vector magnitude is 0, '''the direction CANNOT be [0 0 0]'''. This will cause Phasta to crash. It must have at least one non-zero component. In this case, just set it to [1 0 0].<br />
<br />
scalar_1: Click on the inflow face and go to Create -> scalar_1. Set the field "Type: scalar_1" to 1.8e-7. This is the eddy viscosity at the inlet.<br />
=== Outflow ===<br />
natural pressure: Set "Type: natural pressure" to 0.<br />
<br />
scalar_1 flux: Set this to 0.<br />
<br />
traction vector: Set this to [0 0 0]<br />
<br />
=== TopBottomWalls ===<br />
*These are the walls of the wind tunnel that bound the model from above and below. The terms "above" and "below" are arbitrary, but we typically define them so that their normal points along the z-axis. However, this is not necessary.<br />
scalar_1 flux: Set this to 0.<br />
<br />
traction vector: Set this to [0 0 0].<br />
<br />
comp1: The vector magnitude should be 0. The direction depends on which direction the normal of the wall points. If it is along the z-axis, then this will be [0 0 1]. If it is along the y-axis, this will be [0 1 0]. This attribute signifies a no-penetration condition through the tunnel walls.<br />
<br />
=== SideWalls ===<br />
*These are also arbitrary. But if you already defined the TopBottomWalls, then you already know which walls they are.<br />
scalar_1 flux: Set this to 0<br />
<br />
traction vector: Set this to [0 0 0]<br />
<br />
comp1: Set vector magnitude to 0. The direction should be set to whichever direction the normal of the walls point.<br />
<br />
=== Initial Conditions ===<br />
Initial Velocity: In the model window, go to Selection -> Select Model. In the attribute window, go to Create -> initial velocity. Set this to [1e-8 0 0] <br />
<br />
Initial Pressure: Set to 0<br />
<br />
Initial Scalar_1: Set to 1.8e-7<br />
<br />
=== No-Slip Walls ===<br />
comp3: Set the no-slip walls with comp3. The name should be something meaningful (i.e. NoSlip_comp3). For Boeing, the the only walls that do not get no-slip are the tunnel walls. Therefore, what you should do is go to Selection -> "Select All Model Faces" and then create a comp3. The vector magnitude is 0, and the '''direction must be non-zero''' (i.e. [1 0 0] is fine but [0 0 0] is not). Click Apply and Close. Re-open that attribute, find each of the 6 tunnel walls and click on "Model Associations" at the top of the Attribute Editor and delete them. The faces should be in numerical order in the list. Apply and Close.<br />
<br />
=== Setting Eddy Viscosity on the Wall ===<br />
scalar_1: For the Boeing model, the only walls that don't get this attribute are the tunnel walls. Set this attribute to 0.<br />
<br />
=== Computing Distance to the Wall for the Turbulence Model ===<br />
turbulence wall: For the Boeing model, the only faces that do not receive this attribute are the tunnel walls '''and the jet diaphragms'''.<br />
<br />
=== Identifying Specific Surfaces with an ID Number===<br />
*This must be done for the jet diaphragms in order to turn them on and off. The jets are traditionally ordered from tip to root. So if there are 12 jets, label the jet closest to the tip 1, and the jet closest to the root 12. Click on the surface, go to Create -> Surf ID. Set the value of the ID in Type: Surf ID.<br />
<br />
*This also must be done in order for phasta to compute the aerodynamic force for sets of surfaces. If you want to know C_L for the rudder and stabilizer for example, give all the stabilizer surfaces an ID of 13, and all the rudder surfaces an ID of 14. The value of the ID is arbitrary, but must be different from other surf ID's.<br />
<br />
=== Creating geom.spj ===<br />
*When all the attributes are completed, save the smf file one last time. At the top menu, to the right of "Meshing Process", click on Attributes -> Export Attributes. Save it in the same place as geom.smf and save it as geom.spj.</div>Jema6380https://fluid.colorado.edu/wiki/index.php?title=Creating_geom.spj&diff=366Creating geom.spj2013-07-15T17:44:36Z<p>Jema6380: </p>

Click on the inflow face (which is the face which makes up the front of the wind tunnel) and go to Create -> comp3. Set vector magnitude to the free-stream velocity you want. Set the vector direction to the direction (i.e. if the free-stream velocity moves strictly along the x-axis, the direction would be [1 0 0]). Even if the vector magnitude is 0, '''the direction CANNOT be [0 0 0]'''. This will cause Phasta to crash. It must have at least one non-zero component. In this case, just set it to [1 0 0].<br />
<br />
scalar_1: Click on the inflow face and go to Create -> scalar_1. Set the field "Type: scalar_1" to 1.8e-7. This is the eddy viscosity at the inlet.<br />
=== Outflow ===<br />
natural pressure: Set "Type: natural pressure" to 0.<br />
<br />
scalar_1 flux: Set this to 0.<br />
<br />
traction vector: Set this to [0 0 0]<br />
<br />
=== TopBottomWalls ===<br />
*These are the walls of the wind tunnel that bound the model from above and below. The terms "above" and "below" are arbitrary, but we typically define them so that their normal points along the z-axis. However, this is not necessary.<br />
scalar_1 flux: Set this to 0.<br />
<br />
traction vector: Set this to [0 0 0].<br />
<br />
comp1: The vector magnitude should be 0. The direction depends on which direction the normal of the wall points. If it is along the z-axis, then this will be [0 0 1]. If it is along the y-axis, this will be [0 1 0]. This attribute signifies a no-penetration condition through the tunnel walls.<br />
<br />
=== SideWalls ===<br />
*These are also arbitrary. But if you already defined the TopBottomWalls, then you already know which walls they are.<br />
scalar_1 flux: Set this to 0<br />
<br />
traction vector: Set this to [0 0 0]<br />
<br />
comp1: Set vector magnitude to 0. The direction should be set to whichever direction the normal of the walls point.<br />
<br />
=== Initial Conditions ===<br />
Initial Velocity: In the model window, go to Selection -> Select Model. In the attribute window, go to Create -> initial velocity. Set this to [1e-8 0 0] <br />
<br />
Initial Pressure: Set to 0<br />
<br />
Initial Scalar_1: Set to 1.8e-7<br />
<br />
=== No-Slip Walls ===<br />
comp3: Set the no-slip walls with comp3. The name should be something meaningful (i.e. NoSlip_comp3). For Boeing, the the only walls that do not get no-slip are the tunnel walls. Therefore, what you should do is go to Selection -> "Select All Model Faces" and then create a comp3. The vector magnitude is 0, and the '''direction must be non-zero''' (i.e. [1 0 0]). Click Apply and Close. Re-open that attribute, find each of the 6 tunnel walls and click on "Model Associations" at the top of the Attribute Editor and delete them. The faces should be in numerical order in the list. Apply and Close.<br />
<br />
scalar_1: For the Boeing model, the only walls that don't get this attribute are the tunnel walls. Set this attribute to 0.</div>Jema6380https://fluid.colorado.edu/wiki/index.php?title=Creating_geom.spj&diff=363Creating geom.spj2013-07-15T17:27:11Z<p>Jema6380: </p>

=== Inflow ===<br />
comp3: The name is arbitrary but should be set to something meaningful (i.e. Inflow). Click on the inflow face (which is the face which makes up the front of the wind tunnel) and go to Create -> comp3. Set vector magnitude to the free-stream velocity you want. Set the vector direction to the direction (i.e. if the free-stream velocity moves strictly along the x-axis, the direction would be [1 0 0]). Even if the vector magnitude is 0, '''the direction CANNOT be [0 0 0]'''. This will cause Phasta to crash. It must have at least one non-zero component. In this case, just set it to [1 0 0].<br />
<br />
scalar_1: Click on the inflow face and go to Create -> scalar_1. Set the field "Type: scalar_1" to 1.8e-7. This is the eddy viscosity at the inlet.<br />

natural pressure: Set "Type: natural pressure" to 0.<br />
<br />
scalar_1 flux: Set this to 0.<br />
<br />
traction vector: Set this to [0 0 0]<br />

=== TopBottomWalls ===<br />
*These are the walls of the wind tunnel that bound the model from above and below. The terms "above" and "below" are arbitrary, but we typically define them so that their normal points along the z-axis. However, this is not necessary.<br />
scalar_1 flux: Set this to 0.<br />
<br />
traction vector: Set this to [0 0 0].<br />
<br />
comp1: The vector magnitude should be 0. The direction depends on which direction the normal of the wall points. If it is along the z-axis, then this will be [0 0 1]. If it is along the y-axis, this will be [0 1 0]. This attribute signifies a no-penetration condition through the tunnel walls.<br />

comp3: The name is arbitrary but should be set to something meaningful (i.e. Inflow). Set vector magnitude to the free-stream velocity you want. Set the vector direction to the direction (i.e. if the free-stream velocity moves strictly along the x-axis, the direction would be [1 0 0]). Even if the vector magnitude is 0, the direction CAN NOT be [0 0 0]. This will cause Phasta to crash. It must have at least one non-zero component. In this case, just set it to [1 0 0].<br />
