Hi,
For dealing with non-convex surfaces who have to make sure that all the surfaces (horizontal/vertical) are rectangular. For ex. if you have a surface which is L shape than you have to divide it into two rectangular surfaces, to make it understandable by E+. On visualizing your IDF in a CAD software or Openstudio, you must be seeing non-rectangular surfaces having many line in between. No prob. Just subdivide all those surfaces into rectangular surfaces. That should be fine.
Hope this helps.
