You can now ensure a good energy balance by adjusting the view factor matrix. The VFSM command can adjust the view factor matrix to satisfy reciprocity and/or row sum properties. You may also see small changes in the temperature solution for a radiosity model compared to results from previous releases. These differences are due to a more accurate area calculation for the radiation facets and will yield a more accurate energy balance.

For 3-D analyses, two options are now available for calculating view factors when running Distributed ANSYS:

A new Jacobi iterative solver option has been implemented for radiosity analyses. The Jacobi solver is applicable when using Distributed ANSYS. For more information, see the documentation for the RADOPT command.
