Antisymmetric modeling for panel method solver

  1. Dec 30, 2013 #1
    This is a section from the Pan Air user's guide (Pan Air is a aerodynamic panel-method flow solver).

    I'm confused by the symmetry and anti-symmetry. The first one is easy enough: mirror about the XZ plane (Yimage = -Y, Ximage = X, Zimage = Z). The third one is no symmetry applied. Also easy. But the ones describing the antisymmetry have me stumped because they didn't provide any samples of how they define antisymmetry. For example, the last one is antisymmetry about xz with the full model entered. Does this mean that:

    Yimage = -Y, Ximage = -X, Zimage = Z

    or does it mean:

    Yimage = -Y, Ximage = X, Zimage = -Z?

    Or maybe it means something else entirely. Thoughts?

    I think it's the first one. Yimage = -Y, Ximage = -X, Zimage = Z
