Hi 

I am using AM plugin for modeling Cold Spraying (CS). Cold spray is a coating (or repair) process that impact high velocity and high temperature (bellow melting point) micron size particle to a substrate. The particles are carried by a high temperature and high pressure gas. The particles are attached to the substrate by kinetic and thermal energy.

Now my questions are:

1. Which kind of energy distribution in AM modeler should I choose for this process? Concentrated? Uniform? or Goldak?
2. Since it is not a laser process I don't know what should I put as Absorption Coefficient?

Could anyone guide me in these regards?

Thank you in advance
