Hello everyone,

I am trying to simulate the SOFC stack in Ansys Fluent. The model I am using is two channels connected with MEA. I compiled my own add-on function following the like below.

What I changed is change SOFC open circuit voltage as the function of temperature and mole fraction of species. When I solve the case, I use the second order for the energy equation and the energy relaxation factor is 1. For the rest function, I use a third order solver. As the mole fraction of water cannot be zero, I set up my own initialization which is my numerical model solution as the initial guess. Now the energy cannot be converged. Is anyone can help me with that?

If any information I am not provided, I am happy to respond anytime.

Thank you
