Dear COMSOlers

I try to simulate gas flow taking place in a piece of radial rock sample. The boundary conditions are a bit tricky, beside continuity the pressure has to fulfill two ODEs as well. (Gas is flowing from an upstream vessel into a downstream one through the rock sample) The assembly is shown in the attached jpg file, the model itself is RPD.mph. Upon running however I get an arror message, some problem with the Jacobian, or so. Could you have a short look to it, what do I do wrong? I'm using COMSOL V4, and the Earth Science module.

Tx in advance, best regards

Andras
