Hi all,

Am having some problems with FLUENT in that it is not changing the density of the inert particles via my udf. Can someone check and see if I have made any errors?

Thank you.

A snippet of my udf

Code:
DEFINE_DPM_LAW(bio_algae_test,p,ci)
{
  InertHeatingLaw(p);
  P_RHO(p) = 996.0 + 6.0*(P_POS(p)[2]);
  P_DIAM(p) = 100e-6;
  P_MASS(p) = P_RHO(p)*(4/3)*M_PI*pow((P_DIAM(p)/2),3);
}

why dont you change density from material panel. it provide all these option for inert particles as well. i did it.
