Question #165417 on Yade changed: https://answers.launchpad.net/yade/+question/165417
Christian Jakob posted a new comment: I have no experience with OpenFOAM and also not with the coupling to YADE. Till now I used PFC-CCFD coupling and there are several limitations. The main problem with a so-called continuum-discrete model is the dimensions of the fluid cells. Inside each cell there should be at least 10-20 DEM-particles. If you use less particles, the calculation gets instable. Also (as Chen mentioned) the calculation is quite slow for high numbers of particles. Right now I experiment with a DEM-SPH coupling, but there are other problems with the numerical implementation (e.g. free surface with surface tension, high numbers of SPH particles for accurate solutions and so on).
