[EnergyPlus_Support] Energy Plus, problems with inside view factors [4 Attachments]

["UCSB Building ucsbsim@xxxxxxxxx [EnergyPlus_Support]" <EnergyPlus_Support@xxxxxxxxxxxxxxx>]

Hello,

I wanted to look at view factors for a very simple single room geometry.  I made a simple model and looked at the .bdg file for the view factors.  Some of these don't seem believable to me.  

For instance in the attached pdf, the factor for wall 6-5 is pretty significant although they are 90 degrees from each other and not internally facing.  There is a number of other peculiarities that I cannot figure out.  Another example F2-6 is mostly zero, while F2-5 is significant even though wall 5 is farther than 6 and rotated by 90 degrees.

I've checked numerous times  to see if my labeling is incorrect on the drawing and in the table but everything seems to check out ok.

Any thoughts?
