Hello everyone,
I’m working on the following model from Comsol library:
Batteries and fuel cells>>ht_pem.
When I change the geometry to a more complex one, for example using two or three connected channels instead of a single channel, it gives this error:
Undefined value found.
- Detail: Undefined value found in the equation residual vector.
There are 149 degrees of freedom giving NaN/Inf in the vector for the variable mod1.wH2 at coordinates:
(0.00195433,0.0194965,0), (0.00202966,0.0194855,9.01447e-005), (0.0020981,0.0193663,8.8374e-005), (0.00198618,0.0193565,0), (0.00201391,0.0194573,0.000187002), ...
As mentioned above, I use a model from comsol library, then this error cannot be because of BC’s or Initial variables. Changing the geometry cause this error!
Can anybody help me on this?
I appreciate any help.
