The ANSYS program provides four methods for radiation analysis, each meant for a different situation:
You can use LINK31, the radiation link element, for simple problems involving radiation between two points or several pairs of points.
You can use the surface effect elements, SURF151 and SURF152 for radiation between a surface and a point.
You can use the AUX12 Radiation Matrix method for more generalized radiation problems involving two or more surfaces. (Only the ANSYS Multiphysics, ANSYS Mechanical, and ANSYS Professional programs offer Radiation Matrix Generator.)
You can also use the Radiosity Solver method for more generalized radiation problems in 3-D/2-D involving two or more surfaces. This method is supported by all 3-D/2-D elements having a temperature degree of freedom. (Only the ANSYS Multiphysics, ANSYS Mechanical, and ANSYS Professional programs offer Radiosity Solver.)
You can use the four radiation analysis methods for either transient or steady-state thermal analyses. Radiation is a nonlinear phenomenon, so you will need an iterative solution to reach a converged solution. |
