Hi friends,

I try to use the weak form equation of poroelastic to modeling biot's consolidation using WEAK FROM PDEs. I use the exact same equation and I am pretty the equation is coupled physically. But the result I got is only elastic deformation which is totally uncoupled. I tried many methods, but still can't solve the problem. Is anyone can help me to see what's wrong with my modeling? I attached the mph file. By the way, the verson of comsol I use is 5.0.

Thanks a lot!
