problem whith udf
 

I need to make a source term temperature dependent: Source = C1 + C2*temp

I am using a c++ compiler in a windows system and I make the following program:

#include "udf.h" DEFINE_SOURCE(source_temp, c, t, ds, eqn) { real source, temp; temp = C_T(c,t); source = C1 + C2*temp; ds[eqn] = C2; return source; } When I have compiled it in fuent appear the following mensage:

opening library "libudf"... ERROR: open_udf_library: the system can´t that file.

Please help me.

Thank you.

try "interpreted" instead of "compiled"
