This is an old revision of the document!
This installment of the Cart3D tutorial will walk through the process of generating an intersected component wireframe in VSP. If you haven't built the Onera M6 wing, or you don't have your own geometry to analyze, you should go back to the geometry generation phase of the tutorial or you can download a ready-to-go Onera M6 geometry from the VSP Hangar.
As you proceed through the tutorial to mesh the Onera M6, remember that images have been included as thumbnails, so any place you see a picture, click on it for a larger version.
The VSP interface is the best way to set up and adjust the wireframe resolution, but once that is established, you may want to generate the wireframe from the command prompt.
To generate an intersected triangulated wireframe from the command line, enter the following command:
vsp -batch infile.vsp -compgeom -tri
vsp -batch infile.vsp -compgeom -stl
These commands will generate the unintersected wireframe and write 'infile.tri' or 'infile.stl', respectively.
Once the intersected wireframe is complete, the next step is to prepare the file for analysis in Cart3D. If you are using a STL file, it will need to be converted to a Cart3D TRI file; that process is detailed in the STL to TRI Tutorial. Otherwise, continue to the Cart3D Setup Tutorial.
