Small but mighty!

OpenVSP 3.3.1 may ‘only’ be a bugfix release, but it fixes some really big and longstanding bugs. The fixes are so significant that I considered calling it 3.4.0 — or even 4.0.0!

Whatever you do, update to this version, you’ll be glad you did. Shaded rendering is significantly improved, a few performance improvements, and the problems with 6-series and file airfoils have been fixed.

Bug fixes:

• Fix various problems with 6-Series and File Airfoil types.
• Multiple normal vectors at corners and edges for better shading.
• Improve feature line rendering to reduce artifacts.
• Eliminate transparent surface rendering artifacts.
• Tweak adaptive feature lines to improve consistency of results.
• Add OpenVSP version number to output IGES files.
• Tweak target mesh length calculation to speed CFDMesh.
