Hi Guys,

I want to simulate waves in a numerical wave flume. I will use UDF for moving wall for wave generation. I came across the UDF for a moving wall in CFD forums given below.

#include “udf.h”
#include “dynamesh_tools.h”
DEFINE_CG_MOTION(oscillate,dt,vel,omega,time,dtime )
{
Thread *t;
face_t f; /* define the variables */
t = DT_THREAD(dt);
begin_f_loop(f,t) /* loop over each face in the zone to create an array of data */
{
vel[0]=-2;
}
end_f_loop(f,t)
}

I have two main problems.

1) I don't know how to generate waves of desired parameters i.e time period and height using that UDF.

2) The other issue is that when I want to compile UDF in fluent it gives error saying that " The UDF library you are trying to load is not compiled for the 3D on the current platform (ntx86). The system can not find the specified path "


Please guide me in this matter
I am using ANSYS 15.7 (32 bit)

Thanks
