Probleme with HB-run EnergySimulation

Energy (642 KB)

Hi Alessandro, How did you create the openings? The error is because at least the normal direction of one of the window surfaces is flipped. You need to flip the surface.

Thank you Mostapha for your quick response and your help.

All the normals of the windows (and also those of the other surfaces) are facing the outside of the HBZones, so I think these are the right directions.

I have discovered that if I delete the little window (red circle) the analysis runs. But if I try to flip the surface of this window I have the same fatal error.

Any idea ?
