getting a cell variable
 

Hello dear Engineers :)
I have two Zones in my simulation, one "fluid" and one "solid" and there are two boundaries named "interface" and "interface_shadow" introducing the interface between these zones. i'm trying to implement a UDF and i'm using DEFINE_PROFILE in one of the zones, say fluid, and i've used THREAD_T0 and F_C0 to get the cells and cell threads adjacent to the interface located in the fluid zone. But the point is that I want to get Solid's cells and cell threads next to the interface located in solid zone too! so i have no idea how I can access to those cells while i'm using a DEFINE_PROFILE in one zone and i need cell variables in another zone.. Here's how my code looks like:


DEFINE_PROFILE(flux,f_thread,index)
{
real flux_jump;
face_t face;
cell_t cell;
Thread *c_thread;
cell_t scell;
Thread *sc_thread;
begin_f_loop(face,f_thread)
{
cell=F_C0(face,f_thread);
c_thread=THREAD_T0(f_thread);
scell=F_C1(face,f_thread);
sc_thread=THREAD_T1(f_thread);
flux=A*(C_T(cell,c_thread)-C_T(scell,sc_thread));
F_PROFILE(face,f_thread,index) = flux;
}
end_f_loop(face,f_thread)
}

THIS PROFILE IS TO BE USED ON THE BOUNDARY OF BOTH INTERFACES OF SOLID AND FLUID. I HAD NO IDEA HOW TO GET TEMPERATURE OF SOLID CELL ADJACENT TO INTERFACE SO I JUST USED THREAD_T1 AND F_C1 BUT ERROR OCCURRED SINCE I HAVE NO ACCESS TO GET THE TEMPERATURE OF SOLID CELLS NEXT TO THE INTERFACE. I think I have to get the other DOMAIN by GET_DOMAIN or something. is it right???
THANKS IN ADVANCE.

In your case, I think, the usage of sc_thread in C_T(scell,sc_thread)) throws the error. Is that right?
I also don't know if F_C1(face,f_thread) can be used to access a value of a cell across an interface at all.

I would be glad if someone else could resolve my uncertainty.
