Concrete flow in a mold
 

Hi All,

I hope I can simulate concrete flow in a mold. I have concrete flow through a large mold. The concrete enters the mold from the top entrance and flows downwards. The concrete as you know is a mixture of water, sand, cement, and pebbles. I guess it can be modeled as high viscous fluid with solid particles in it. Under certain circumstances, the small pebbles would not suspend in the concrete but precipitates. Is it possible to simulate concrete flow using STAR? If so, can you tell me how to do it?

Many thanks in advace
