How to extract the wall shear stress (wss) vectors from the ybar file containing time-averaged statistics or the restart file containing instantaneous solutions?
1. Go to the directory containing the reduced one-part geombc.dat.1 file and the ybar file, for example, ybar.352000-372000.0
2. Run the following command one by one
mkdir wss create a new directory to put the wss vtk file
cd wss
ln -s ../geombc.dat.1 create a softlink of the geombc.dat.1 file
cp ~/develop/phasta/wallshearC/wallshearC/input.config .
cp ~/develop/phasta/wallshearC/wallshearC/solver.inp . input.config and solver.inp here have no real meanings, the only reason is that the code need to read them
ln -s ../ybar.352000-372000.0 ybar.372000.0 create a softlink of the ybar file, notice that the link only takes the final time step in the file name
echo 372000 > numstart.dat
ehco 1 > itagybar.dat tell the code to extract wss from the ybar file
mpirun ~/develop/phasta/wallshearC/wallshearC/bin/x86_64_linux-icc/wallshearC.exe-openmpi > dumpWSS.log 2>&1 & run the code
tail -f dumpWSS.log
