Description
I just started using SediFoam. It would be great if I will get rids of this problem. I am using sediFoam Solver for fluid-particle interaction. I am giving a run time of 50 sec... but, my simulation stops at 0.5 sec. giving below result:
Need the help of experts.
My workstation has a RAM of 32 GB and during the simulation, RAM utilization is around 20- 30% of the total. I think the size of RAM is not the issue, somewhere LAMMPS has the issue which I am not able to figure out.
