Please help me for a 3 phases model.
 
I'm using fluent for my Msc. I have successfully modeled a VOF model of a bridge in a river. My Superviser asked me now to work on the impact of the bridge on the river scouring. I tried to use an Eulerian model with 3 phases (air, water and sediments) but it doesn't work. Could someone show me how to handle this problem?

Merci, JJ Richelieu,

Hi，i have the same problem, i don't think scour will be simulated well by fluent based on multipase flow theory, the traditional method is based on exner equation, this can be simulated successfully by mesh deformation using UDF. Good luck!
