Hanz is on a distinguished road

I'm currently writing my first UDF but am a bit stuck

I need to call the properties of the gas in which the inert particle resides in order to write the equation for drag, such as temperature, Cp etc. I'm currently using the Macro DEFINE_DPM_DRAG(particle_drag_force, Re, p).

Any help would be great.
