Failed to find consistent initial values

Please login with a confirmed email address before reporting spam

Dear COMSOL users!
I am trying to model wormhole formation during the acid injection in the reservoir. It is two scale model: Darcy scale and pore scale. I am using 3 physics: Darcy law, transport of diluted species in porous media and Domain ODEs and DAEs. Initial porosity is distributed random: por = por0 + rn(x,y); But when I am doing simulation I have error message "Failed to find consistent initial values.
Last time step is not converged.
- Feature: Time-Dependent Solver 1 (sol1/t1)"

So, I couldn't find where is the problem. Actually problem is associated with porosity.

Can anyone help me to decide this problem? Thank you everyone, in advance!
