** Severe ** Problem in interior solar distribution calculation (CHKBKS) ** ~~~ ** Solar Distribution = FullInteriorExterior will not work in Zone=114718
** ~~~ ** because vertex 1 of back surface=P_114718_5_0_0 is in front of receiving surface=W_114718_2_0_0 ** ~~~ ** (Dot Product indicator=26.0348) ** ~~~ ** Check surface geometry; if OK, use Solar Distribution = FullExterior instead.
What could be the possible reason?
I am simulating a passive solar scenario with trombe walls.
