Hi,
My project is about cfd modeling of GDL in PEM fuel cell. I have air, water vapor and water liquid in this layer. The most important thing is water phase change which causes mass transfer between water vapor and water liquid due to condensation and evaporation. IN this layer for air and water vapor I need to use species diffusion and for water liquid I want to use navir-stokes.

So my question is, from fluent, cx, comsol or openfoam which one should i choose?

I want to know which one of these software are easiest to work in my case and don't need programming or very little.

Thank you very much
