IbscourFoam question
 

I am currently using PSU's ibscorFoam to simulate local scour of bridge piers. This is also one of the tutorials they provided. The problem I am currently facing is that when using Paraview to view the calculation results, I cannot find the interface between the water and sediment in the calculation result like other solvers. Such as, alpha_ SEDIMENT, has anyone encountered the same problem?
