Re: USRBIN Energy deposition

Beatrice,

You can use FLUKA to determine the source of heat in your heat equation.
To do that you can score energy deposition in a mesh, transform the units to
suit your problem, apply the specific heat capacity (careful, this is
temperature dependent!), and plug that in your evolution code, e.g. ANSYS.
(maybe ANSYS already takes care of the specic heat capacity step, I don't know
that), which will diffuse the heat inside the body and take care of radiation
with the surrounding temperature.
I am not sure that I understand your specific questions, but I guess they
are not FLUKA questions anyway. Just score enegy deposition and make sure
that your mesh is fine enough that you don't underestimate the heat peak
wherever your beam strikes the target. The rest is a mathematical problem.

Hope this helps a little.
By the way, this is not an uncommon application so maybe people using
ANSYS can give you further tips.
