Point source for heat analysis

Post by keithsloan52 » Sat Aug 29, 2020 5:54 am

Sorry newbie FEM question - Rather than a Plane is it possible to have a point source as input of heat energy? If yes how about multiple point sources?

Thinking of GEANT4 Monte Carlo simulations, Assuming one can get access to coordinates, velocity vector, timing and details of the particle where they hit a new solid, if one could then perform some sort of heat FEM analysis. I guess one problem would be that one does not know how much energy goes into heat production and how much into lattice vibration.

Thinking about it the energy from one particle is probably not going to be that significant.

Hi

There is no reason why you could not have random point sources (to the closest node) in FEM. See for example this simple case:

I would think you have quite many incoming particles. If the number of particles is greater than number of nodes it certainly makes sense to everage out their contribution and give the resulting heat flux as a field.
