Robert Caulk proposed the following answer:
Hello Ibraheem,

I don’t quite understand the question. Is there an issue with
triax.porosity?

Are you asking “how to scale the heat capacity of thermalengine to simulate
a material with a lower porosity than the dem packing”

If yes, you can scale it by multiplying by the ratio of porosities:

Cp_scaled=Cp*triax.porosity/desired_porosity

Cheers,

Robert
