  Hello, in udf, C_DPMS_SURF_YI(c,t,i) macrocommand how to use? i want to calculate the gas density on the surface of the particle, not the gas density of the grid in which the particle is located. C_DPMS_SURF_YI(c,t,i) How to use this macro? Please give your comment

  That macro is defined here, https://ansyshelp.ansys.com/account/Secured?returnurl=/Views/Secured/corp/v242/en/flu_udf/flu_udf_DataAccessMacros.html%23flu_udf_sec_dpm_macros and isn't density. Particle density is set in the materials panel, but TP_RHO(tp) is available.
