PROBLEM COMPILING!!! PLEASE HELP!

Toni Cominceanu

I HAVE A PROBLEM AND I DO NOT KNOW WHAT TO DO. I WANT TO PUT A SINUSOIDAL VARIABLE VELOCITY_INLET. I WROTE THIS IN C++: " /************************************************** ********************/ /* unsteady.c */ /* UDF for specifying a transient velocity profile boundary condition */ /************************************************** ********************/

#include "udf.h"

DEFINE_PROFILE(unsteady_velocity, thread, position) { face_t f; begin_f_loop(f, thread)

{

real t = RP_Get_Real("flow-time");

F_PROFILE(f, thread, position) = 0.0 + 90.0*sin(188.5*t);

} end_f_loop(f, thread) } " AND WHEN I PUT THE NAME "unsteady.c" IN INTERPRETED UDFs UNDER SOURCE FILE IN FLUENT 6.012 IT SAY THIS: "cpp -IC:\FLUENT.INC\fluent6.0/src -IC:\FLUENT.INC\fluent6.0/cortex/src -IC:\FLUENT.INC\fluent6.0/client/src -IC:\FLUENT.INC\fluent6.0/multiport/src -I. -DUDFCONFIG_H="<udfconfig.h>" unsteady.c error: udf compiler: cannot execute cpp -IC:\FLUENT.INC\fluent6.0/src -IC:\FLUENT.INC\fluent6.0/cortex/src -IC:\FLUENT.INC\fluent6.0/client/src -IC:\FLUENT.INC\fluent6.0/multiport/src -I. -DUDFCONFIG_H="<udfconfig.h>" unsteady.c "

WHAT CAN I DO, PLEASE TELL ME. I NEED TO MAKE A DIRECTORY AND SAVE "unsteady.c" THERE, OR WHAT... I DON'T KNOW WHAT TO DO.

THANKS!
