Hi, 

I want to use DPM_DEFINE_PROPERTY to specify a custom particle density, Here is my UDF :

#include "udf.h"

 

DEFINE_DPM_PROPERTY(droplet_density,c,t,p)

{

  real rho= P_RHO(p);

  real Tp = P_T(p);

  

 

   rho = 508 + 967.57693 * pow((1-(Tp/374.15)),0.33);

  

 

  return rho;

}

 

The error after interpreting:  error: macro "DEFINE_DPM_PROPERTY" requires 5 arguments, but only 4 are given.

 

what is the fifth argument?

I'm guessing you've read an older copy of the documentation and then compiled in the current release. So, the argument would be to use the documentation in the solver Help....  More usefully, https://ansyshelp.ansys.com/account/Secured?returnurl=/Views/Secured/corp/v231/en/flu_udf/flu_udf_DPMDEFINE.html%23flu_udf_sec_define_dpm_property
