Patchy saturation in porous media under load

Please login with a confirmed email address before reporting spam

Hi,

I have just started to work with a COMSOL, so maybe my questions are not that smart...

I work in a COMSOL version 3.5a, with Earth Science Module (poroelastisity). My model is attached. The problem is that wherever I try to solve it, it alway ends up with an error:

Error: 6250
Failed to evaluate variable Jacobian.
- Variable: T
- Geometry: 1
- Subdomain: 2

I just don't know what else can I define for the subdomain 2 to make this model work. If some one can give me a piece of advice, i would be very grateful.

It is coming from this variable: rho_solid_1(T[1/K])[kg/m^3] . comsol uses a temperature based variable. You can either use a normal number or define the temperature T in "constants".
