Exporting to PHASTA
After the partitioning performed via Chef in the last steps, we have the problem domain in a form that the PHASTA executable can read. Make a directory named "Run". This will contain all of the simulation data from this case. Remember that for this onRamp tutorial we have partitioned our case of interest to 8 parts. Therefore we will also create a subdirectory named "8-procs-case". In this subdirectory make softlinks to the N=8 restart and geombc and restart "checkpoint" files that where constructed. When in this subdirectory a good command to do this is the following :
ln -s ../../Chef/8-1-Chef/8-procs-case/restart* . ln -s ../../Chef/8-1-Chef/8-procs_case/geombc* .
Also create a numstart.dat file. This file will specify the time and timestep that the simulation has completed to. Use the following command in the "Run/8-procs_case" directory :
echo 0 0>numstart.dat
Build the executable/specify runtime parameters
What remains is to determine the version of PHASTA to build and run. Since there are a bunch of researchers working on PHASTA at any given time, there are many branches/versions of the main code. If you are a part of the research cohort you may be directed to phasta-next, but many of the same steps may be taken from the public version.
Retrieve/build a version of PHASTA code
Navigate to your home directory. Create a directory here named "git-phasta". In a web browser, navigate to the online git repository for phasta-next and select the "clone" or "code" icon. The result should be the simular to the following picture, where a pop-up gives a web address:
Copy this address and within the "git-phasta" directory execute the following command and enter your github credentials:
git clone https://github.com/PHASTA/phasta-next.git
After this is finished their will be a subdirectory created named phasta-next that contains the code tree that you wish to build. Back within the git-phasta directory create another subdirectory named: "build_phasta-next".
Additional notes
If there is a specific branch off of phasta-next that you'd like to build, navigate to phasta-next and use the following command:
git checkout "branchname".
If this is a branch that I will be working on for a while, I tend to alter the build and code directories according to the branch-name.
