"A formal definition of convex is that any straight line passing through the zone intercepts at most two surfaces"
It's pretty obvious that this isn't the case in your model, here's a line that intercepts 4 surfaces for your larger zone.â??
ÂHi,ÂDoes anybody know how to fix the "non-convex warning". The following warning says my roofs are not convex!!!ÂIt makes me mad. I did everything I knew but the problem still remains. It is very odd to me because I can run some other model with similar zone shape without any warning.I am not even sure about the effects of this warning on the result of my model.Would you please help me to fix it.ÂI attached the IDF file to this Email.It may helps.Thanks in advance.Best,Tilak.************* Beginning Zone Sizing Calculations** Warning ** CheckConvexity: Zone="ZONE_S_U4", Surface="OBJ:0159" is non-convex.** ~~~ ** ...vertex 5 to vertex 6 to vertex 7** ~~~ ** ...vertex 5=[10.15,17.55,14.59]** ~~~ ** ...vertex 6=[10.15,11.80,14.59]** ~~~ ** ...vertex 7=[9.35,11.80,14.59]** Warning ** CheckConvexity: Zone="ZONE_S_E", Surface="OBJ:0067" is non-convex.** ~~~ ** ...vertex 2 to vertex 3 to vertex 4** ~~~ ** ...vertex 2=[6.75,11.80,17.09]** ~~~ ** ...vertex 3=[7.55,11.80,17.09]** ~~~ ** ...vertex 4=[7.55,7.90,17.09]** Warning ** DetermineShadowingCombinations : Surface="OBJ:0159" is a receiving surface and is non-convexÂ
