Hi,<\/p>\n

I have 2 zones in the same position which contains solid type and fluid type zone simultaneously by using TUI command:<\/p>\n

mesh\/modify-zones\/copy-move-cell-zone<\/p>\n

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.<\/p>\n

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? <\/p>\n

Thanks,<\/p>\n

Here's simply UDF code:<\/p>\n

DEFINE_SOURCE (Porous_solid_energy, c, t, dS, eqn)<\/p>\n

{<\/p>\n

   real source; \/\/ Heat flux between Porous solid and Porous fluid source term<\/p>\n

    real TS =C_T(c,t)  ; \/\/Solid temperature<\/p>\n

    real TF = 100 ; \/\/Fluid temperature<\/p>\n

    source  =  0.0; \/\/ Ignore<\/p>\n

    dS[eqn] = 0.0; \/\/ Ignore<\/p>\n

    Message("TS = %g 
\n",C_T(c,t)); <\/p>\n

    return source;<\/p>\n
