## MachUpX Mesh Generation

MachUpX can be used to create reasonable meshes for PyPan. The following advice should be followed:

* If NACA airfoils are being used, be sure to specify ```"NACA_closed_te" : True``` in the geometry dict for each NACA airfoil.
* For each wing under ```"CAD_options"```, be sure to specify ```"round_wing_tip"``` and ```"n_rounding_sections"```. For one-sided wings (e.g. vertical stabilizers), you will also want to specify ```"round_wing_root"```.
* MachUpX does nothing to handle the intersection of multiple lifting surfaces. It is not recommended to try to create meshes for this type of geometry using MachUpX.
