Version 2.2.4 contains a collection of bug fixes that improve the CFD mesher. Various users have run into these problems, so if you use CFDMesh, you should certainly upgrade.

Bug fixes in this release:

• Guarantee attachment of wakes to constructing edge
• Relax tolerance to better match wakes down body splits
• Rewrite curve tessellation integration for quality in extreme cases
• Introduce curve split sources for mesh quality near intersections
• Size curve distance table to match underlying topology

The wake changes should help guarantee mesh topology when wakes are turned on. There were certain cases that could arise where a wake would not properly attach to the generating trailing edge, or the edge of a body that aligned with the wake. Both of these situations should be … Read more

The 2013 OpenVSP Workshop will be held 7-9 August in San Luis Obispo California. There is a $99 registration fee.

The agenda will include presentations and tutorials. Topics will range from introductory to advanced modeling techniques, connections between VSP and analysis tools, and updates on recent/ongoing developments in VSP.

Please email Rob McDonald if you would like to present at the workshop. Please include a title or short description of what you would like to present. We can’t guarantee to accomodate everyone, but we are trying to construct a comprehensive workshop.

The workshop information web site is online and will be updated as the agenda is set.

Version 2.2.3 contains a triplet of small bug fixes that have bitten some users. I have been putting these off waiting for an upcoming feature release, but now seems to be the time to get these out there.

Bug fixes in this release:

• Threaded version check
• Fix CG contribution of point mass components
• Fix CFDMesh half models when a surface is actually cut

Placing the version check in its own thread allows VSP execution to continue during the version check. This is significant for situations where the computer has internet connectivity, but the VSP web server is experiencing problems. The HTTP library used by VSP does not let you change the timeout from 60 seconds, so in these situations, VSP paused for 60 seconds on startup.

The CG contribution of point mass components was cal… Read more
