Confusions about orientation in Pointwise
 

Hi,

I am doing a 2d rae2822 computation with SU2, using mesh from Pointwise. Here, I have three questions:
1. Do we need to check the orientation every time after generating mesh?
2. I should get the same, at least very similar, computational results from several small domains owning the same right-hand-rule orientations, and one big combined domain following the right-hand-rule, correct?
3. I just realized that, in my case, when all the domains had right-hand-rule orientation, the computation was diverging. However, when I used the default orientation after generating mesh, it could give me some good results. I do not quite understand this part.

Hope to get some helpful replies from everyone! Thanks a lot!
