Isobaric compressibility

Please login with a confirmed email address before reporting spam

Hi all,
I am trying to couple free and porous medium flow to heat transfer in porous medium to model ground water flow and heat diffusion/convection in the ground using subsurface flow module
I need to account for isothermal compressibility (T=cte) as well as isobaric compressibility (p=cte) .
the isothermal one (beta) is shown in the variables in equation view and in the equation it self (free and porous medium flow, fp).
the isobaric one (alpha) is shown in the variables in the equation view but not in the general heat transfer equation (heat transfer in porous medium, ht).
I was wondering if comsol is accounting for this parameter?

your help is much appreciated
