Hi

This is my first UDF and I keep getting a undeclared variable on line 13.

Any help would be appreciated.

Thanks

Will

#include "udf.h"

DEFINE_PROFILE(inlet_y_velocity, thread, index)
{
real x[ND_ND], y;
real t = CURRENT_TIME;
face_t f;

begin_f_loop(f, thread);
{
F_CENTROID(x, f, thread);
y = x[1];
F_PROFILE(f, thread, position) = 10*(1+0.3.0*sin(2.0*3.141592654*(20.0*t));
}
end_f_loop(f, thread);
}

Hi,

try this:

F_PROFILE(f, thread, index) = 10*(1+0.3.0*sin(2.0*3.141592654*(20.0*t));

Bests,

F_PROFILE(f, thread, position) = 10*(1+0.3.0*sin(2.0*3.141592654*(20.0*t)));


...is this an error?

I'm not an expert but you can try this:
F_PROFILE(f, thread, position) = 10.*(1.+0.3*sin(2.0*3.141592654*(20.0*t)));

Hi

Yea that was a typo.

Changing it to index gives a parse error.

Thanks
