URGENT PLEASE- Two-sided wall

Mahyar Mohammadian

Dear Freinds,

i am going to model a domain which contains solid and fluid zone. the solid and fluid zone are meshed. after i compile it to fluent, it produce a shadow-wall for the wall which is intersection of fluid and solid zone. i want to set heat generation for intersection wall and let fluent to compute heat transfer in two domain. in the boundary condition i set heat generation and also set wall as copupled, so fluent can compute heat transfer itself. but it can not compute while i set wall thickness for wall intersection. if i set wall thickness for it, the answer is depended to amount of wall thickness. in my physical domain there is no thichkess for the wall intersection. what shoud i do?
