Hi,

I have 2 zones in the same position which contains solid type and fluid type zone simultaneously by using TUI command:

mesh/modify-zones/copy-move-cell-zone

Assuming the boundary condition is set well, I'm trying using UDF to access solid zone temperature data mentioned through C_T(c,t) macro. However, I found that I get fluid temperature data while debugging.

According to UDF MANUAL, UDF can access "Flow variable" by using C_T ,C_R, etc . Therefore , I'm wondering if there's any way to access solid temperature data of each cell?

Thanks,

Here's simply UDF code:

DEFINE_SOURCE (Porous_solid_energy, c, t, dS, eqn)

{

   real source; // Heat flux between Porous solid and Porous fluid source term

    real TS =C_T(c,t)  ; //Solid temperature

    real TF = 100 ; //Fluid temperature

    source  =  0.0; // Ignore

    dS[eqn] = 0.0; // Ignore

    Message("TS = %g  ",C_T(c,t)); 

    return source;

}

Hi, again
I found that I hooked the UDF at wrong zone by using THREAD_ID to check the zone ID
The conclusion is that Ansys Fluent can access solid variables as well as fluid by using macro mentioned in UDF manual.
Best.

Sure. Thanks!
