This tutorial is targeted at experienced Cart3D users, if you are new to Cart3D, you should start with the example cases distributed with it. There are a number of ways VSP can be used to work with Cart3D -- each with pros and cons. This tutorial will have a 'choose your own adventure' style to it to cover the different options. Feel free to skip around and explore the different paths.

This is a known bug. Until it is fixed, the workaround is pretty easy. Once you leave the Foil tab by selecting another tab in the MS_Wing editor, simply click on the component name in the Geom Browser (usually sitting just to the left of the MS_Wing editor).

VSP allows for quick and easy geometry generation and modification. Cart3D allows for fast, robust, and accurate Euler solutions on complex geometries. Together, it is possible to execute quick and effective design cycles. text/html 2012-02-29T09:42:03-04:00 http://www.openvsp.org/wiki/doku.php?id=oneram6&rev=1330526523&do=diff This component of the Cart3D tutorial will walk through the process of creating a simple geometry to analyze with Cart3D. For this example, we will build a model of the Onera M6 wing. Onera M6 Definition The Onera M6 wing is a standard transonic test case frequently used to demonstrate CFD codes. The geometry, experimental setup, and experimental results are documented in AGARD AR-138.

OpenVSP allows the user to create a 3D model of an aircraft defined by common engineering parameters. This model can be processed into formats suitable for engineering analysis. The predecessors to OpenVSP have been developed by J.R. Gloudemans and others for NASA since the early 1990's. On January 10 2012, OpenVSP was released as an open source project under the NASA Open Source Agreement (NOSA) version 1.3. text/html 2012-02-29T15:37:44-04:00 http://www.openvsp.org/wiki/doku.php?id=tutcompgeom&rev=1330547864&do=diff This installment of the Cart3D tutorial will walk through the process of generating an intersected component wireframe in VSP.

The only special care required is when setting the extent of the domain using 'autoInputs'. Preparation In order to run Cart3D, you must have the following files in a directory where you want to run the analysis. text/html 2012-02-28T01:37:14-04:00 http://www.openvsp.org/wiki/doku.php?id=tutsetup&rev=1330411034&do=diff Using Cart3D with a model created in VSP is mostly just like using Cart3D with any other model. However, VSP and Cart3D use different axis conventions by default. In VSP, +X runs from nose to tail, +Y runs out the right wing, and +Z is up. In this example, we will analyze a symmetrical flow condition with a symmetry condition on the XZ plane. text/html 2012-02-28T01:36:39-04:00 http://www.openvsp.org/wiki/doku.php?id=tutstltotri&rev=1330410999&do=diff Although STL files have their weaknesses, it is sometimes useful to use them as an intermediary between VSP and Cart3D. Cart3D comes with the 'stl2tri.pl' script which automates the process of converting a STL file to a TRI file. This script relies on the admesh program to infer the mesh connectivity and to fix any small problems with the mesh topology or geometry. text/html 2012-02-29T15:38:13-04:00 http://www.openvsp.org/wiki/doku.php?id=tutunint&rev=1330547893&do=diff This installment of the Cart3D tutorial will walk through the process of generating an unintersected component wireframe in VSP and then using Cart3D's intersect utility to process the geometry into a single watertight body.
