High reaction value due to wind load (wind tunel simulation)

[geralA8ZZM]

Hi, this project has been nagging me for the past few days, due to unreasonable uplift forces in some points.

The worst case is in node 165: for load case 10 (wind Y-) the suction values in the area above are around 0.6 KPa, so I would expect the reaction to be approximately 0.6*22*6 = 79.2 KN, instead I get 167 KN, more than double.

Can someone tell me what's wrong? I've been trying a couple of things to find whatever makes that reaction tick but to no avail.

Uplift is not created by suction above columns, but also by horizontal wind efforts

Sorry for the late response, the horizontal forces due to wind Y should cause moments on that column, only the vertical suction should cause uplift, right?

Anyway, after some trial and error I realized there was a problem in generating wind loads aplied to the side panels, and the uplift was caused by huge axial forces on the beams that should not exist, likely a bug

No
