Hi Chris,
I tried to reconstruct the CFD results of "twoSpheresGlowinskiMPI" case, however it seems not possible right now, due to the refined mesh generated during the run.
So i thought run the case with only 1 core will solve this issue, but with dataExchangeModel twoWayMPI the solver does not allow running on single core, even I changed the
mpirun -np $nrProcs $debugMode $solverName -parallel 2>&1 | tee -a $logpath/$logfileName
to
$solverName > $logpath/$logfileName
It still doesn't work due to calling of MPI function or something like this. Furthurmore, how to set the coupling file for the dataExchangeModel twoWayFiles? It has no option to call the LIGGGHTS file in DEM folder.
twoWayFilesProps
{
couplingFilename "*****.vtk";
maxNumberOfParticles 10000;
}
So how to figure out this issue, in order to run coupling simulation on single Core?
Best,
Daivid

You can, but not using MPI. You should be able to do this using the file coupling

hi Chris,
hi Chris,
how to turn of MPI and use file coupling instead?
Thanks,
David

Hi David,
Hi David,
you need ot use the file coupling on both the LIGGGHTS and CFDEMcoupling side

Hi Chris,
i am using the file coupling on both the LIGGGHTS and CFDEMcoupling side, but the simulation is always waiting for file "$casePath/CFD/couplingFiles/radius1". I wonder if there is some preperation work that i am missing?
Thanks,
wenxin

wait for file "../CFD/couplingFiles/radius1" using twoWayFiles
Hi Wenxin,
When using the twoWayFiels as the dataExchangeModel, I also met the problem you said above. so have you find a method to solve it?
