unsaturated thermal material properties

Hello Feflowers,

I'm at my first heat transport model and I'm wondering what feflow does with the thermal properties when in unsaturated mode...

1- Are the heat conductivity and capacity varied with saturation?
2- When the materials are unsaturated, are these properties modified to take into account the solid-air properties?

I took a quick look at the basic equations in feflow's reference manual, thermal section, but even with it, I'm not entirely sure about it. Probably it's because I'm too good at reading math equations!

What do you think? Any thoughts is welcomed.

Thanks,

Thomas

1. Yes, they are.
2. Air is considered as non-existing for heat storage and conduction, i.e., it does neither store nor conduct heat.

I think the same for unsaturated flow material properties. Is it?
