Hi,

I have some questions when I use EDEM 2022-recurdyn r9v2 coupling.

The whole coupling simulation was slow when I chose gpu(cuda/opencl) solver on edem2022, even slower than CPU solver.

I try to choose gpu solver to run the same coupling simulation on EDEM 2020 and recurdyn r9v2,  and I found that simulation running very fast.

Total number of particles on edem is about 500000.

I really confuse about this question. Could you please tell me how to improve simulation speed on EDEM 2022-recurdyn r9v2 coupling, thanks!

    Hi, do you see a speed impact if you run EDEM stand-alone for the case? It should help determine if it's the EDEM case or the coupling to RecurDyn.

     

    For the case do you have a user defined particle size distribution, if so what is the min/max scale?

     

    Regards
