Moving Reference frame - UDF - Moving mesh

Hello everybody,

Does any one know what does the following UDF exactly do?

DEFINE_ADJUST(vel, domain) {

Thread *t;

cell_t c;

real time = RP_Get_Real("flow-time");

thread_loop_c (t, domain)

{if (THREAD_ID(t) == 2)

{ THREAD_VAR(t).fluid.velocity[0] = sin(time); THREAD_VAR(t).fluid.velocity[2] = cos(time);

}

} }

I would like to update my grid location at each time step. Thank you, modisa
