Reacting Flow in Porous Media of the Membraneless Fuel Cell

Hi All,

Please, I need to simulate the reacting flow in porous media at membraneless fuel cell. Firstly, I am just trying to simulate laminar flow and transport of diluted species. Furthermore, I am not able to obtain the values of he reacting flow in porous media at Gas Diffusion Electrode of the microchannel fuel cell. Cause I have some error with my model as following:

Failed to find a solution for the initial parameter.
Segregated group 1

Singular matrix.

There are 1 void equations (empty rows in matrix) for the variable comp1.rfcs2.Pinlinl1.
at coordinates: (0,0,0), ...
and similarly for the degrees of freedom (empty columns in matrix).
In segregated group 1:
Returned solution is not converged.


If anyone can give me some suggestion it would be really welcome.
Thank you very much.

regards,
Yusuf

Hi Yusuf

This usually happens when the boundary conditions are not enough. Can you post your model?
