The present Viewfactor program makes commercially available advances in the computer calculation of viewfactors and obstruction for finite element thermal models developed at MSC.Software Corporation. These advances are principally:
1. Improved performance as measured by the product of speed and accuracy in determining obstructed views and calculating viewfactors, and
2. A viewfactor analysis program designed specifically for finite element modeling.
