Effects on fvSolution file on calling mpi run

I'm getting different behaviors while rereading fvSolution file using mpirun and without using it.
I modified my fvSolution.H file and added a fvSolution.C (also added it to Make) fvSolution.C Code:
bool::Foam::fvSolution::read() { Info << "fvSolution rereading" << endl; return solution::read(); } Code:
public: virtual bool read(); tutorials/heatTransfer/buoyantBoussinesqSimpleFoam/hotRoom 1. sequential run: (without mpi) Code:
./Allrun & echo " " >> fvSolution # this just puts a blank line at the end of fvSolution, causing it to be reread 2. mpi parallel run Code:
./Allrun.par& mpirun -np 4 buoyantBoussinesqSimpleFoam -parallel > log.bbsf & echo " " >> fvSolution How can I explain that behavior ? (I use OpenFoam 2.3.x version, if that matters at all) This doesn't make any sense to me. Allrun.par is just a tailored version of Allrun. Code:
#!/bin/sh cd ${0%/*} || exit 1 # run from this directory # Source tutorial run functions . $WM_PROJECT_DIR/bin/tools/RunFunctions application=`getApplication` runApplication blockMesh cp 0/T.org 0/T runApplication setFields runApplication decomposePar # runApplication $application # runApplication mpirun -np 4 $application -parallel # ----------------------------------------------------------------- end-of-file Last edited by aaron99; May 27, 2019 at 08:20. |
