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.
