Problem with ANSYS surface to surface enclosure type.

  Hi,
  I am currently trying to do a 2D thermal model. This needs to have a enclosure type: Perfect, however, ANSYS steady-state thermal refuses to run the simulation unless the enclosure type is set to "open". However, this would give me the wrong results.
  I have attached an image of the model.

  For the enclosure to be perfect, the sum of view factor for a surface should be = 1. This means that the heat radiating from a surface must fall on some other surface(no ambient radiation). Is that the case in your problem? Have a look at 1. https://www.youtube.com/watch?v=gWsogRf9VIM and 2. https://www.youtube.com/watch?v=DRru2pBUF5A.
  Regards Ishan.
