Hello everyone

Tried to vary speed of disk in Fluent using this code

#include "udf.h"
DEFINE_PROFILE(inlet_mf,thread,i)
{
float t = CURRENT_TIME;
face_t f;
begin_f_loop(f, thread)
{
F_PROFILE(f,thread,i) = t*5;
}
end_f_loop(f,thread)
}
------
error message
" ... inlet-mf : wrong return type: double udf function expected". Yes the inlet_mf is for inlet mass flow rate, but why wouldn't this work. What is the correct alternative? Please, thanks.
