UDF direction
 

Hi all!

Can someone give me guidance how to change the velocity in the preceding udf from a x-velocity to a y-velocity....I'n really new to udf writing

Thanks

#include "udf.h"
#include "dynamesh_tools.h"

DEFINE_CG_MOTION(trans, dt, vel, omega, time, dtime)
{
/*reset velocities*/
NV_S(vel, =, 0.0);
NV_S(omega, =, 0.0);

if (!Data_Valid_P ())

{
Message0("\n\nNo data->No mesh motion!!!\n\n");
return;
}
/*set x-component velocity*/
vel[0] = 1;
}

x-component velocity = vel[0]
y-component velocity = vel[1]
z-component velocity = vel[2]

cheers

Hahaha thanks! Wish I knew this sooner!
