Boundary condition for Porous media in NLTE

Hi guys,
i realized a NLTE model for porous media flow.
I used a UDS to compute solid equation.
Now i have a question about BC?
I should apply this one on a wall.

q_tot=q_fluid+q_solid
T_fluid=T_solid

on the same wall...
the two fluxes are known...Tf and Ts are unknown

So i if i apply the two fluxes on two domains Tf will different from Ts and it's a problem

I think it'll be necessary an iterative solution...Can you help me?

qwerty753 ，have you solved this problem, Now I have faced the same question.
please tell me the method, thanks
