CFDEM®coupling - User Forum

Hey everyone, I am currently using High performance computing cluster to run cfdem program, if I want to restart the process for many times, what process should I follow here. How am I gonna use restart files generated once the program was interrupted. I know how to restart the program for once, but not sure about restarting it for many times.

Thanks!

Hello All,

I am running CFDEM simulations of internally heated particles, with an external code determining each particles heatSource value. Currently I am able to run a single iteration, steady-state, case where by

Hi CFDEM,

Hello Users,

I am a new user for CFDEM coupling and I am conducting my thesis modelling high efficiency stairmand cyclone. I am using pisoFoam solver at the part of CFD and snappyHexmesh tool for building cfd mesh this part it goes well without any issue. when I came to the part of parallelization I faced the following error which is attached below..
I am stuck at this point I would really appreciate any help to be able to proceed with my thesis.

Regards.

Hi guys!

Did anyone know how to correctly set up the wear model in CFDEM coupling?
I am trying to set up, but the results looks strange.
and where to find the wear model in Liggghts?

The result is shown below.

Hi all,

Hi, I am apparently a new user of CFDEM. I have two issues:

#1
I wanted to insert a large number of particles 100000, with radius 0.0005 in cgs unit system and wanted to insert few at some interval. Therefore, I used the following in my init script

Dear All,

To study the cfdemSolverPisoSTM tutorial, as I only decrease the number of particles in the bed from 1005 from 500. the error comes after resetting data from restart file, as
