 August 14, 2012, 16:47 Radiosity-FEM method - light source simulation #1 New Member   Jose Luiz Join Date: Aug 2012 Posts: 3 Rep Power: 11 I am master's degree student and in my work I'll need to do a simulation of light source in ANSYS. I read several articles about light source simulating by ANSYS through the Radiosity-FEM method. I would appreciate any help. I need some information about the light source modeling and simulation by ANSYS using thermal radiation: 1st) Is it possible to do a radiation simulation (DT or MC method) in ANSYS Mechanical (multiphisics) or only in ANSYS CFD? 2nd) I didnt found any tutorial of thermal radiation simulation using Discrete Transfer or Monte Carlo, somebody have any example or tutorial? I really thank the attention.

Are you modeling radation through a participating fluid medium? If not, are you confusing ANSYS mechanical terms and CFX methodologies? If you are just using ANSYS mechanical, I suggest you submit your question to xansys.org.

The R-FEM method was used for modeling of special light sources and to compute lighting of surfaces from these sources with very good results. ...For modeling of the light sources in the CFX environment was used combination of the Finite Volume Method and the radiation method which are included with the CFX (The Discrete Transfer Model and The Monte Carlo Model)."
