Divergence on some panels when using an angle of sideslip

[aidanjungo]

I think I mention this issue a few weeks ago, here's more details about it.

In the CPACS file attached I calculated some points with different angle of attack and sideslip (see the aeromap "test_Aeromap_30points_aoa_aos"). For some value couples the aerodynamic coefficient are extremely high, in this case for:

• aoa = -2 and aos= 4,5 and 6 degree
• aoa = 0 and aos = 6 degree

I try to change the panel discretization, the coefficient values change but the problem is still the same.

I plotted the pressure coefficient for one of this configuration and we can see that it diverges on some cells. I imagine it could due to the fact that the wake of these cells "touch" other cells of the tail...
