Hello to everyone.
I have been trying to modify the twoSpheresGlowinski tutorial from CFDEM in order to simulate a coupled flow (sedimentation) of particles (~400μm diameter) into a non Newtonian fluid.
My main problem seams to be that no cells are selected to be refined and Courant number increases as the steps progress.
These is the log output of the 7th step where it cruses.
Selected 0 cells for refinement out of 8000.
Selected 0 split points out of a possible 0.
Courant Number mean: 1.78356e+41 max: 2.46448e+43
What do I have to change???
