Heat transfer in a porous material submerged in water

I am looking to do model heat transfer from within a porous polymer disk with water in the pores.

There is no place in the HTPM (heat transfer in a porous matrix) model in which to indicate that the fluid in the pores is water. How do I separate those two functions?

Hi,

Of course there is a place where you can define the fluid properties. Look at the attached jpg.

Look at the equations in the user's guide, the nomenclature is the same as in the interface (for fluid : rho, k, C_p and for the porous matrix: rho_p, k_p, C_p,p). This way you are sure that you enter the right numbers at the right place.

But there is no place for me to say which material to get the information from. The only way for me to do it is to manually input the data for water, but I want an easy way to be able to change this from water to other media for example without having to go through these particular numbers each time.

Is there another way?
