Run the phasta code with the following in the solver.inp file:
Use STGinflow BCs: True
STG SurfID: 411
STG BL Height: 0.0027
STG U_0: 75.0
STG Number of Modes: 405
STG Mode Growth: 0.01
STG Mesh Growth: 1.13
STG Channel: False
Collect STG Energy Spectrum Data: True
STG Energy Distance Tolerance: 0.0005 #(allowed position error from the distance from STGinflow (helpful if the spacings are specified from the model and you know the position))
Energy Spectrum at Distances: 0.0 0.00675 0.0162 #(from defined STGinflow face in +xdir)
- The third to last line listed here and below matter for gathering points to gather nodes on
- Try to have a time step a fraction of a cycle of kMax(=approx. 75.0)
- ex:1/(kMax*U_0*percent_of_rotation), or 1/(75*75*0.05)=0.03))
Configure n-procs_dir
Make vars directory within n-procs_case dir.
mkdir n-procs_case/vars
- Delete
xyzts.datif from a previous run. - If there are additional Probe points you want, create a fresh
xyzts.datfile with some header (like 4 1 1 1 1) and those points
(additional functionality may be included later by modifying common/bcSTG.f#236 ex: inputing frequency of data reading (right now at every timestep))
Extracting Ubar
- As was done to extract a
STGInflow.datfile for the IDDES domain from the RANS domain, open the/projects/tools/Models/STG/FlatePlate/RANS_FullPlate/Run/computeVARsforFLATEPLATE.pvsmopen the RANS case that you wish to use - Create filers on that Case that find the points in
xyzts.dat - Right-click the "GradientOfUnstructuredDataSet1" and select "Change Input" and select the filter that you just created.
- File>Save_Data and save as
PV-points.csvin the Run above the LESn-procs_case - Copy Riccardo's matlab script
/projects/tools/Models/STG/FlatPlate/RANS_FullPlate/Run/Prepare_STGInflow3.mto this directory
Creating an energy Spectrum
- Copy John's matlab scripts to the Run directory
/projects/tools/Models/STG/FlatPlate/STG_Plate/RunNew/John_Load_Varts_Directory.m /projects/tools/Models/STG/FlatPlate/STG_Plate/RunNew/John_Compute_STG_Eng_Spectrum.m (TODO)
Run the latter. i.e. matlab execute "John_Compute_STG_Eng_Spectrum( N_procs_case_directory,dt,StartTime )" -Output(TODO)
