particles for radiative heat transfer with monte carlo

[fab6]

Hi ,

I am quite new to amrex and started using particle class. The aim is to build a kind of photon Monte Carlo approach for radiative heat transfer based on particles which can run on GPU and CPU.

Up to now I started with some first benchmarks for a simple generic setup, black walls with optical thick medium. Later, I would like to include non-black complex EB-stl surfaces and local refinements and transfer fields from an openfoam fire simulation.

Now I saw on the NASA presentation (slide about load balancing with particles) by Andrew Myers from 2018, that the particle
class might not be the best for this application; at least this was my understanding. Maybe it refers only to the actual load balancing, but at least I wanted to ask, if you can recommend using the particle class for this kind of application or if there is some better approach?
Thanks!
