soleimanian is on a distinguished road

I simulate a building in front of wind load and the structure is symmetry.
In part of ANSYS meshing, I use of tetrahedral mesh and define body of influence due to have three zone around the building for control mesh sizing.

Quality of mesh is fine, but when after run calculation, pressure contour show asymmetric on face of building.
I don't know exactly its related to meshing or other factors of setup?
