OpenVSP 3.1.0 and VSPAERO Released

OpenVSP 3.1.0 brings the much awaited release of VSPAERO, the new vortex lattice solver that has been developed to be a part of OpenVSP. There are a few other improvements and fixes, but I’m certain everyone will want to update to get their hands on VSPAERO.

VSPAERO is a thin-surface code for inviscid subsonic and supersonic aerodynamics. It is multithreaded to make the most of common multi-core computers and uses a mesh agglomeration scheme to improve scaling with large meshes. The matrix is solved with an iterative GMRES solver. VSPAERO includes a simple actuator disk model to represent propulsion-airframe interaction and also the ability to calculate common stability derivatives.

Check out this introductory video on VSPAERO.

OpenVSP Hangar Now Supports v3 Files!

The OpenVSP Hangar has been updated to support v3 files.

To upload a v3 file, just follow the normal procedure. The Hangar will detect the file version and will automatically tag the file so users can search based on the version number.

One of the great new features of OpenVSP v3 is the addition of user-defined custom components. The Hangar provides a great way to share these components too.

To share a custom component, just create a model containing a default instance of your user-defined component. Upload that model to the Hangar and tag your file with ‘custom component’ for everyone to see and share. Any custom component may be extracted to a stand-alone *.vsppart file by saving it from the ‘Type Editor’ GUI. … Read more

OpenVSP Workshop 2015

OpenVSP Workshop 2015

We are pleased to announce that the 2015 OpenVSP Workshop will be hosted on the East Coast this year.

Please save the dates of August 11-13. We will be holding the workshop at the National Institute of Aerospace in Hampton, VA.

As before, the OpenVSP Workshop consists of presentations and tutorials by VSP developers and power users. Topics range from introductory to advanced model building, reports on cutting edge development, and work that real users are accomplishing with OpenVSP.

Given the major redesign of Version 3.x.x and the influx of new users, we will focus the first day (8/11) on beginners and those who would like a thorough run through the entire interactive interface and explanation of the parameters. We will also present what we have … Read more

OpenVSP 3.0.4 Released

OpenVSP Version 3.0.4

OpenVSP 3.0.4 is mostly a bug fix release. This should fix a bunch of issues with DegenGeom in preparation for things to come. Also fixed are a bunch of problems with 6-series and file airfoil types. Anyone using v3 should certainly update.

Bug fixes in this release include:

  • Six series leading edge creep
  • Crash for very thin six series airfoils
  • Fix problem copy/pasting file airfoils
  • Update overall wing aspect ratio display
  • Don’t deselect Geom when executing DegenGeom
  • Fix sign assumption in z camber of DegenGeom for reflex or inverted foil
  • Make export file names match primary file name
  • Save Vehicle level parameters including file save options
  • Fix wing updating when total parameters changed
  • Enable extracting point cloud from slices
  • Write

OpenVSP 3.0.3 Released

OpenVSP Version 3.0.3

OpenVSP 3.0.3 includes a handful of bug fixes and small improvements to the 3.0 series. ┬áVersions 3.0.1 and 3.0.2 included quick fixes for urgent last minute bugs — but they did not include a complete release note.

API Users Note:
The calling arguments in four functions were changed: CutXSec, CopyXSec, PasteXSec, and InsertXSec.  See Wiki for details.

Improvements since 3.0.0 include:

  • Extend API to allow changing Wing Driver Groups
  • Add VSPExit to API to return exit value to host batch environment
  • Add DegenGeom to API / Scripting
  • API now references Cut/Copy/Past/Insert XSec to Geom not XSecSurf

Bug fixes since 3.0.0 include:

  • Fix crash caused by dynamic Parm GUIs and undo-friendly sliders (3.0.1)
  • Fix crash when mixing 4-digit airf

OpenVSP 3.0.0 Released!

Version 3.0.0 compared to version 2.3.0 includes too many changes and improvements to list. OpenVSP v3 is a near total re-write that has been three years in the works. Many thanks to the entire core OpenVSP team. This is what you’ve all been waiting for!

Since 2.9.7, version 3.0.0 has a handful of small fixes and features, and one major new feature that has long been in development.

Improvements include:

  • Fit Model tool to perform least squares fit of VSP model to points
  • Point Cloud Geoms to support Fit Model
  • Import of point clouds as well as conversion from MeshGeom
  • Improved Undo, where slider actions are not recorded
  • SubSurface support in API
  • Improvements to advanced parameter linking.

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

OpenVSP 2.2.5 Released

Version 2.2.5 contains a collection of bug fixes and small features. Some of the features look like bug fixes — and some of the fixes look like small features.

Fixes/features in this release:

  • Save CFD export options.
  • Automatically add *.vsp extension when saving.
  • Add *.ram files to file-open dialog.
  • Write propellers to XSec *.hrm files.
  • Fixed PovRay *.inc file bug.
