ximik is on a distinguished road
Hello,
I am working on writing a UDF that does the following steps:

1) Gets the face value for the solar and total radiation flux. I have been trying to use the call function : solar_flux=F_SOLAR_SOURCE(f,t);
rad_flux=BOUNDARY_RAD_HEAT_FLUX(f,t);
2) Stores the face information (F_UDMI (c,t,1)= solar_flux) in the adjacent cell ( cell_t c0=F_C0(c,t,); Thread *t0 = THREAD_T0(t); C_UDMI(c0,t0,1) = F_UDMI (c,t,1)
3) Performs some internal calculations using C_UDMI(1) and some other cell properties that are pulled.


I am using the DO model, with solar load model. I have a thread that is dedicated to the object of concern, but not sure what to do with that, i.e. should I make it as a solid and apply the UDF to it, or are there ways of just extracting this information from a surface (with the necessary boundary conditions applied to it).

Thank you
