SandFall animation WPF

Question

Hello I need to create a SandFall with lots of sand grains and the sand can flow to the bottom. Application should have some realistic physics. Is this something thats possible? I tried to do that with Farseer Physics Engine but the application worked too slow. And also where should I start? Thank you. - Eugene.

I don't know. That is far beyond any physics and mathematical programming that I have done. If you don't mind some comments anyway then I have some. If the program keeps track of every grain of sand then it makes sense to me that it would be slow. Perhaps you should try to design something that processes the sand as a combination of grains. I assume that the flow rate would depend on gravity so you would need a 3D surface with varying rates of flow. I have seen programs that simulate flames. Perhaps some of the techniques in those programs will help.
