I want to define water velocity as velocity-inlet in boundary condition panel and patch the zone of sand. and I want sand to be stationary untill the water puor to it. but I don't know how to define sand in boundary condition, and Is it important to take each of the phases as primary and secondary? I am in urgent need. please help me
