restarting a coupled CFDEM simulation

Submitted by run_cfd on Tue, 01/28/2014 - 14:10

Hello CFDEM users,

I have to run a coupled problem, in which I have to change the boundary conditions in the CFD side in steps. In CFD side it could be done very easily (just by changing the bc at the current time and specifying the startTime in system/controlDict file.
But I am not able to restart the DEM side from current time, because I am not able to write the liggghts restart file on this current time. Please suggest if somebody have faced the similar problem and know how to write the liggghts restart file on some specified intervals when running a coupled problem with CFDEM.

Thanks is advance,

Hello MLD,
have a look at the case ErgunTestMPI_restart in tutorials/cfdemSolverPiso.

Thanks Alice,
It works now. For other cases also.
