Hooking a UDM function.

Tushar_Telmasre · March 23, 2017, 02:53

I did write a simple code to save my temperature data in a udm.

#include "udf.h"
real temp;
cell_t c;
Thread *t;
begin_c_loop(c,t)
{
temp = C_T(c,t);
F_UDMI(c,t,0) = temp;
}
end_c_loop(c,t)

it is not getting interpreted.
I want to know which macro I need to use to hook this function to fluent.
I want to further define a custom field function with value udm0 and plot it at the end of calculation. The contours of that should be same as the contours of temperature.

Can anyone please have a look and suggest any mistake? also how and where do I hook this UDF?

I would use DEFINE_ON_DEMAND. See the help for more info.
