hello everyone!

Can anyone please give me some tutorials (or their link) related to 3D UDFs. All the examples given in fluent tutorials are in 2D.

Thanks in advance!

Regards

I have read many examples of 2D UDFs, but there's no example of 3D UDF given in fluent tutorial.

I wrote a 2D UDF to vary contact angle along x axis at the bottom surface. I am not sure whehter it would work for 3D as well.

The UDF is :

#include "udf.h"

DEFINE_PROFILE(contact_angle,t,i)
{
real y[ND_ND];
real x;
face_t f;

begin_f_loop(f,t)
{
F_Centroid(y,f,t);
x=y[1];
F_PROFILE(f,t,i)=90-(1700*x);
}
end_f_loop(f,t)

}


x varies from 0 to 0.05
y varies from 0 to 0.01
z varies from 0 to 0.02

The contact angle is defined at y=0 and does not change with z direction.
