Hello everyone,
I am trying to simulate and fuel cell in fluent by building my model through an UDF. Regarding the mesh/geometry, I have this structure:

2x CGL - Fluid
2xCL - Fluid
1x Membrane - Solid
2x Flow channel - Fluid
2x Bipolar plate - Solid

The problem is that I have different Cp for the different domains. I can manage how to make them different in the Fluid zone, since I can add different materials for the solid part. In the fluid zone, I can only use one type of mixture. Is there any way to do this? Using 2 different mixtures or define it based on the thread?

This is an scheme to show clearly what I need to do.
