SubscriberHi there,
I have a UDF that defines particle source terms in Fluent 17 using DEFINE_DPM_SOURCE with the pressure-based solver.
I need to get the mass flow into the cell containing the particle for this calculation.
I tried using F_FLUX but I keep getting a segmentation fault error, is the mass flow not stored for faces of cells?
The relevant code that causes the crash (if I remove the "f_flow = F_FLUX(f,f_t);" line it doesn't crash):
DEFINE_DPM_SOURCE(Source, c, t, S, strength, p)
{
  Thread*f_t;
  face_t f;
  int n;
  real f_flow;
  Â
  c_face_loop(c, t, n)
    {
      f = C_FACE(c,t,n);
      f_t = C_FACE_THREAD(c,t,n);
      f_flow = F_FLUX(f,f_t);
  }
}Â

Forum ModeratorI'd move from R17 to 2024R2 for a start. F_FLUX is defined here  https://ansyshelp.ansys.com/account/Secured?returnurl=/Views/Secured/corp/v242/en/flu_udf/flu_udf_DataAccessMacros.html
