Hi!

I am trying to model PEM water electrolyzer with Ansys Fluent using the eulerian multiphase modeling. For anode, I consider the boundary condition as velocity inlet only defined for the water (primary phase) while for oxygen (secondary phase) no inlet is considered. I am applying mass source term for both primary phase and secondary phase where water gets consumed and oxygen being produced. While doing so, the volume fraction for the secondary phase becomes 1 and the primary phase volume fraction becomes 0 causing divergence. Can anyone tell how the phase volume fraction is being calculated and what's the possible reason for this problem?
Thanks in advance.
