Honeybee error Outward facing angle of subsurface differs more than 90.0 degrees from base surface

Hi everyone, I'm having a problem with my simulation in Honeybee; I've a free-form surface that was triangulated - it's a closed brep and all that - and if there are few triangles (such as 80 faces) the simulation works perfectly, however, if there's like 300 faces with windows (glazing) it starts to shows this error "Outward facing angle of subsurface differs more than 90.0 degrees from base surface".

All the model and the triangulations were done in grasshopper. I've already tried to flip the faces normals, reajust the glazing ratio but nothing works. Any ideas?
