OpenVSP — a free parametric CAD software for designing and analyzing the geometry of aircraft (CFD, FEM). The program is developed by employees of NASA Langley Research Center and enabled to the software list NASA Software Catalog.
From September 17-19, 2019, the «OpenVSP Workshop 2019» was held, where the developments and plans for the 3.19.x branch were presented. On November 9, the release of OpenVSP 3.19.0 took place, and just over a week later, a corrective release 3.19.1 was issued.
The development branch OpenVSP 3.19.x includes three most anticipated innovations: VSPAERO 6.0.0, Generic XSec Editor and auto-generated API documentation using Doxygen. Additionally, extensive work was done to improve and fix bugs. A significant part of this work was carried out by the team of ESAero, sponsored by the U.S. Air Force Research Laboratory.
Change log (in releases 3.19.0 and 3.19.1)
Most changes were aimed at improving cross-platform compatibility, accuracy of calculations, and stability.
We ask all users who utilize VSPAERO to restart models in VSPAERO 6.0.0 and report any issues encountered. While changes to the VSPAERO GUI are minimal, users can utilize CLI commands to access all advanced features. The most significant feature is the ability to install multiple unsteady rotating bodies. Over time, a GUI interface will also be added to use all capabilities of the analyzer.
In addition to all program updates, now users Ubuntu 18.04 can download the DEB package (thanks to Cibin Joseph for the packaging work), and a 64-bit EXE is also available for users. Windows Fully unsteady, accurately temporal analysis;
