Cross-Section Viewer Window


The Cross-Section Viewer window enables visualization of a normalized representation of the cross-section profile you have selected. In some cases, this is useful for verifying that the model representation on the screen is true to the underlying curve. This feature is also very useful for matching known cross-section profiles to your designed curves. Note that you can change the color of the cross-section line and also insert images into the XSec View background to closely match known sections or photos.

The fully virtual 2020 OpenVSP Workshop is coming soon!

The OpenVSP Workshop is scheduled for September 15-17 this year and will be a fully virtual, free, and open event!  There are still open time slots remaining so we are opening our call for papers or presentations to include everyone interested. If you are using OpenVSP to educate or in university design courses, tell us about your experiences. If you have had successes or failures using OpenVSP in your work or hobbies, we’d like to hear about them. If you have found a new and interesting way to leverage OpenVSP to integrate into other tools or to streamline your processes, let us know.  Viewers no longer need to register.  Simply follow the links when they are posted!  Those interested in presenting should make their intent known by August 31 to allow sufficient time for planning.

The Workshop will be streamed through the OpenVSP YouTube Channel.  Real-time comments and questions will be available through the YouTube Live Chat on the feed.  The moderators will either answer these in the chat feed or forward the questions to the presenter to answer directly.  Presentations will start at 11 a.m. and continue until 5 p.m. each day (U.S. Eastern time).  Each talk will begin promptly at the top of the hour and be a maximum of 45 minutes in length providing a 15 minute break for Q&A and setting up the next presenter.  The event schedule will be posted on the 2020 VSP Workshop Wiki page along with links to the live feed by September 7th.  Topics to be presented will range from introductory material to advanced modeling techniques as well as ongoing software improvements and feature additions. This year we also hope to host live developer sessions where advanced users will walk you through building OpenVSP from the Git source and how to build and use the OpenVSP Python API.

Please email Brandon Litherland if you have any questions about the Workshop or would like to be a presenter. We look forward to seeing you!

OpenVSP Ground School Content Updated

The primary focus of the Ground School team is to get OpenVSP Fundamentals out to the user community as quickly as possible.  To that end, we are continuously working on adding content and regularly updating the tutorials.  Users are welcome to subscribe to the Posts page so they can stay up to date with the training content**.  We will post notifications to this page summarizing new content including the Chapter, Subject, and Topic name.

** Subscription to this site is currently under improvement.  Certain domains are not allowing notifications to go through. This feature will be activated when we can ensure that users will properly receive confirmations and notifications regardless of email domain.  Thank you for your patience!


Parameter Details and Drag-and-Drop


OpenVSP maintains uniqueness for all parameters in all components of every model. You can quickly view the details of every accessible parameter in your model by clicking on the Name of that parameter in the GUI box. For example, to view the Span parameter of a Wing component, click “Span” in the Sect tab. You can use the information shown to identify the Name, Group, Max/Min, etc. as well as Links and Advanced Links for that parameter. OpenVSP also allows you to quickly populate variable selection areas by dragging-and-dropping the variables. You only need to click and drag the variable name (button) to the variable selection or add region and then drop. VSP will either automatically select or add the parameter depending on where you drop. This feature is exceptionally useful for variable selection operations within Design Variables, Variable Presets, and Linking.
