Dear friends,

What follows is the UDF file which aims to calculate the number of "escaped" particles from the domain in a dpm (discrete phase model) problem. Although the number of those particles is reported in the Fluent console, I need that UDF file for an optimization study.


When I compile that, the following warning and error is reported by Fluent:


--------------------------------
..\..\src\particle_cells_count11.c(19): warning C4133: '=': incompatible types - from 'particle_struct *' to 'Tracked_Particle *'
..\..\src\particle_cells_count11.c(19): error C2039: 'next': is not a member of 'tracked_particle_struct'
C:\PROGRA~1\ANSYSI~1\v162\fluent\fluent16.2.0\src\ dpm\dpm_types.h(680): note: see declaration of 'tracked_particle_struct'

--------------------------------


Line number 19 was highlighted below (loop(p,I->p)).

Any idea is highly appreciated.


Thank you...
