Hello.
Im trying to build a 2D model of a tank filled with water, inside this tank there is a wall that is moving and creating waves, after this i want to track the particle trajectories to asses the best condition for particle grouping.

i made the wall inside the tank movie using a udf, but now i see its movement does not effect the "water" in the wave and thus not creating any velocity changes.

how can i make the wall movement affect the interior water using fluent.

Thank you.
Viktor

I attach my UDF for wall movement and a picture of the tank with the wall

#include "udf.h"
#define PI 3.14

DEFINE_CG_MOTION(movingwall,dt,vel,omega,time,dtim e)
{
Thread *t;
face_t f;


t=DT_THREAD(dt);

begin_f_loop(f,t)
{
vel[1]=0.05*sin(2*PI*time);
}

end_f_loop(f,t)


}

Any Help?
or direction on witch model should i use?

I suggest trying out "dynamic mesh"
