scour sediment model

javadrasooli · October 26, 2014, 13:08

Hello every one,

I am trying to model scour sedimention around a single Pier. For sand component, I made a box and stretch it at whole bottom of mesh (as a sand layer). So I followed the structure of user's Manual but since the sand is not suspended in water should I make a Mass-momentum sources?!
2. When I add a Fluid Region and adjust a value for Suspended Sediment concentration, I face a Problem in solving that says :"negative fluid density"
So please guide me.

Best regards,
Javad
