PFV - Yade

Asked by Othman Sh on 2020-03-11

Hello,

I have a general question about the PFV model in Yade. According to the papers that document the model [1,2], the finite volume mesh is created with tetrahedral elements. My question is, is the mesh size strictly controlled by the triangulation which means that the user cannot refine the mesh? Is the model sensitive to mesh refinement or it will automatically create a mesh that is optimum (i.e. results are independent of mesh size)?

Thanks,
Othman

Hi, the mesh is intrisicaly particle-based. It can't be refined in any way.
