Hello,

I am new to comsol 4.2 and I started with the built in model of ht_pem in the model library.
It seems that changing the dimension of this model (L) to make the channel longer result in a problem for solver that can not evaluate some of parameters.

I have no idea why such a change result in this error so any comments is appreciated.

"
Failed to find a solution for all parameters,even when using the minimum parameter step.

Segregated group 3

Attempt to evaluate negative power of zero.

Function: ^

Returned solution is not converged.

Thanks,
Siamak

Hi

I had same problem, but when I increased the value of inlet velocities, it solved.

Tell me if your problem solved.
