we are receiving an error for a building we are simulating. All the windows (interiors) are having the same problem. It is a window that connects two zones. Can you give us a possible cause of the error which is obviously affecting the results of the simulation. ** Severe ** Problem in interior solar distribution calculation (CHKBKS) ** ~~~ ** Solar Distribution = FullInteriorExterior will not work in Zone=KE_IS_NOT_01 ** ~~~ ** because vertex 1 of back surface=93327F is in front of receiving surface=B86747
** ~~~ ** (Dot Product indicator=0.2570) ** ~~~ ** Check surface geometry; if OK, use Solar Distribution = FullExterior instead.
