Hi
why UDF containing the following line
if (RP_Get_Integer("coordeval")==1) {
coord_coeff(f_thread);}

gives

Error: rpgetvar: coordeval: undefined variable

What is the solution? I"ll be gratefull if anyone can help.
Thanks in advance.

Because the variable input should be set using GUI. You should make a GUI, else should set it manually in the UDF and delete rpgetvar.

Hi
Thanks a lot for your quick response. I could not follow you. "coordeval" is a scheme variable. But value of coordeval is not known. Have I to put in the following way in UDF of Fluent?

#define coordeval value

If possible Please explain in detail. Have a nice time.

Use 1 for coord_c... to enable it.
