Hi All,

I want to simulate the movement of a particle in a room with the use of the discrete phase model (DPM) and obtain its trajectory. Meanwhile, there is a radiation field in the room. I need to define a function by integrating the local incident radiation and particle tracking time step. However, I cannot model the radiation field by Fluent.

radiation field generates heat source in your case, isn't it?
if yes, all you need is to apply additional heat source using UDF (which could be coordinate dependent or uniform, or whatever)

Hi AlexanderZ,

Thank you for your time.

Unfortunately, I have very limited experience with DPM simulations.
The only thing I can recommend is to read ansys fluent customization manual
Look for Discrete Phase Model (DPM) DEFINE Macros
