Hi everyone!

I've been trying to parallelize the velocity inlet UDF in order to run it on the parallel solver. As it should be running on an HPC cluster it is not possible to use the expression for inlet boundary condition and UDF interpretation doesn't work there.

/***********************************************************************/
/* Velocity.c                                                          */
/* UDF for specifying steady-state velocity profile boundary condition */
/***********************************************************************/
#include "udf.h"

DEFINE_PROFILE(inlet_x_velocity, thread, position) 
{
  real x[ND_ND];                /* this will hold the position vector */
  real y;
  face_t f;

  begin_f_loop(f, thread)
    {
      F_CENTROID(x,f,thread);
      y = x[1];
      F_PROFILE(f, thread, position) = (y/.005);  /* it is just an example */
    }
  end_f_loop(f, thread)
}

I've found the UDF manual's example useful but still cannot assign it to the aforementioned UDF.

I'd appreciate your help.

Thanks

It might just work without any changes, did you try that already?
