Get the error
invalid type for integral binary expression: double ^ int
when I try to interpret the following UDF

#include "udf.h"
DEFINE_PROFILE(mass_flow,thread,index)
{
real x[ND_ND];
real y;
face_t f;
begin_f_loop(f,thread)
{
F_CENTROID(x,f,thread);
y = x[2];
F_PROFILE(f,thread,index)=35-((-0.75*(34.44-32.78)*y^2)+(1.75*(34.44-32.78)*y)+32.78);
}
end_f_loop(f,thread)
}

What could be the reason

regards
Luke

The error was using the operator ^ as in y^2
So switched to y*y and it works !!

Hi,
try y^2. (with dot) instead of y^2
even the command pow(y,2.) should be fine

Best regards
