Sand slide model about sediment transport in OpenFOAM

liuxiaojian2015 · January 30, 2018, 09:42

Hi all,
As we all know. The bed level change was calculated with Exner equation. Then, the displacement of point was interploated, and mesh was update. And then, the steepest slope angle of boundary face of sediment was calcuted. If the steepest angle of a face exceed the repose angle, the face should be adjusted according to the mass conservation, in order to statisfy the need of repose angle, the face should rotate around the center of face. However, it is diffcult for me to calculate it, i.e, some errors appear. Any one could discuss it with me?

Have you figured our how to apply the sand-slide model correctly? You may find some ideas from this paper:
