3D solid-liquid mixture in stirred tank

Hello,

I've been using Comsol for a couple of months but there is still a lot to learn. Right now I'm trying to simulate a solid-liquid mixture in a stirred tank in 3D. I started by modifying 2D simulation from the model library but I can't get it to work. The simulation stops right at the beginning with this error message:

Failed to find consistent initial values.
Matrix has zero on diagonal.

I've attached the model file for you to see.

Any help will be appreciated.

Regards, Ehsan
