Failed to find a solution for the initial parameter.
In Velocity u, Pressure p:
Divergence of the linear iterations.
Returned solution is not converged.
Not all parameter steps returned.
Hi, i am working on modelling PEM ammonia electrolyzer with serpentine flow fiwld, where ammonia will be the final product, using fuel cell and electrolyser module in COMSOL Multiphysics. I checked all the boundary conditions. I am getting these errors despite tried changing various parametric conditions. Here I used seggregated step solver instead of fullly coupled as I couldnt find solution for that. How to find the root cause for the divergence? please help me in resolving this issue.
Half cell reactions-
Anode- 3H2O -> 1.5O2 + 6H+ + 6e-
Cathode- N2 + 6H+ + 6e- -> 2NH3
At cathode both reactions can occur. Included both in porous electrode coupling reactions.
Here I used Brickman equation, Secondary current distribution, Transport of concentrated species interfaces and coupled them. I need the results of the final concentration of ammonia produced and secondary current distribution.
