Coupled CFD-DEM simulation - losing particles
Asked by
Kahlil Fredrick Cui
Hello!
I am doing a very simple simulation exercise with coupled CFD-DEM, with Esys particle for the DEM part. Its very similar to the slope_friction.py simulations, only now the particles are underwater. Somehow, after several iterations, the number of particles decrease (as if they disappear) which causes the simulation to crash. I made sure that the time steps are small enough to minimize computational errors.
I know this problem is not solely attributable to ESyS and it might be to coupling code parameters. I am just hoping someone here might have some idea as to why this happens. Any input helps!
