OpenVSP 3.2.3 Released

OpenVSP 3.2.3 is a periodic update. Nothing huge here shoving it out the door, but enough good things have accumulated in the last month that a release should be useful to people. Both fixes and features, everyone should update.


  • Added slew control to skinning. Slew controls the direction of surface curves ‘in’ the surface – where Angle is ‘out’ of the surface.
  • Change default skinning parameters to simulate v2′s Fuse2 component.
  • Export wireframe as Plot3D file (thanks Joe Derlaga)
  • Improve nearest point search algorithms in Code-Eli should help CFDMesh and FitModel.
  • Cache derivative calculations in Code-Eli – should speed CFDMesh some
  • Added reversed triangle detection and removal to CFDMesh
  • Tweaked CFD

OpenVSP 3.2.2 Released

OpenVSP 3.2.2 is another bugfix release. Some small, but a few that have been longstanding problems. Everyone should update to get the benefit of these fixes.


  • Specify units when writing STEP files.
  • Specify dimensional tolerance when writing STEP files.

Bug fixes:

  • Fix wing updating with zero tip chord, zero taper, etc.
  • VSPAERO Remove additional swirl component in front of actuator disk.
  • Fix airfoil trimming bug introduced in 3.2.1
  • Eliminate divide by zero for trim/closure parameters with zero chord.
  • Fix bug introduced when DegenGeom GUI was made programmatic.

OpenVSP 3.2.1 Released

OpenVSP 3.2.1 is a release of mostly bugfixes. Most of the fixes are small items expected to accompany a big release like 3.2.0. However, the most significant fix has been a problem with all of v3. So, although it is small, everyone should go ahead and update.


  • Background control GUI converted to be programmatic

Bug Fixes:

  • Fix inconsistent orientation of triangles from CompGeom
  • Fix orientation of symmetrical actuator disk normal vectors
  • Improve feature lines and XSec highlights with blunt trailing edges
  • Don’t write un-needed Matlab DegenGeom file for VSPAERO
