OpenVSP 2.9.5 Third Beta for v3 Released

This version includes a large number of changes both features and fixes.  Some of these fixes took longer than expected — and one of the features is pretty big, so this release took much longer than anticipated.  Look for subsequent releases to be smaller and more frequent as the bugs are chased out.

Warning:  One bug fix required an incompatible change in how skinning is calculated.  If you have used a Fuselage or Stack component with skinning, you will need to adjust your tangent strengths — the geometry will be wrong when you open it.  I am very sorry for this inconvenience.

Note:  The file extension for custom components has been changed from .as to .vsppart.  Similarly, the file extension for scripting has been changed from .as to .vspscr… Read more

OpenVSP 2.9.0 — First v3 Alpha Released

The first public alpha release of the v3 re-write of VSP is now available for download. Please take it for a test drive. For real work, please continue using 2.3.0.

For the past two years, a dedicated team has been re-writing VSP from the ground up. The core v3 team responsible for this work so far is: Alex Gary, J.R. Gloudemans, Yue Han, David Marshall, and Rob McDonald.

The v3 effort is a major refactoring and rewriting of VSP. Although it should look/feel mostly the same to casual users, everything is different under the hood. I will write a series of blog posts in the coming weeks on the user-visible changes and how to make the most of them.

The alpha series will be numbered 2.9.X, leading to an eventual production-ready 3.0.0. This alpha release is not for production use. It … Read more

OpenVSP 2.3.0 Released

Version 2.3.0 contains one significant feature and a small bug fix. Version 2.3.0 is likely the last 2.X feature release for VSP. We will continue making 2.3.Y bug fix releases for a long time.

For some time, almost all developer effort has been focused on the pending 3.X project. VSP v3 is a near total rewrite keeping everything you love about VSP, but ushering in new features galore and a more maintainable code base. We hope to release a not-for-production-use alpha version of v3 for users to begin testing soon.

Fixes/features in this release:

  • Add ability to model outer domain boundary in CFD Mesh.
  • Match multi-body edge shares in CFD Mesh. (Thanks Sriram R.)

You can now generate a CFD Mesh including the outer boundary. Some volume grid generators need to start with a full… Read more
