Gridding a JAXA Standard Model Symmetry Plane
 

I am creating a surface grid for the JSM from the .igs CAD file provided on the AIAA HiLiftPW website. I have created a box domain around the airplane and am trying to create a grid on the symmetry plane as shown in the image.

I have tried the following methods, to no avail:
- Assemble Special -> Domain, selecting the JSM fuselage boundary and the boundary of the box domain
- Trim by Surfaces, creating a database surface on the symmetry plane and trimming out the fuselage gap using the JSM fuselage boundary
- Interpolate, using the JSM fuselage boundary to the box boundary

I appreciate any tips you may have!

When assembling an unstructured domain with a hole, when using Assemble Special you'll need to ensure that the outer and inner boundaries are oriented in the opposite direction. For example, your outer loop should be clockwise and inner loop should be counter-clockwise.
