An OpenVSP model may be subsequently reduced into geometrically simpler representations from thick surfaces to plates to sticks, and finally, to points all while maintaining metadata about the model. This process is called DegenGeom. Different model representations may be used for different purposes. For example, the plate representation is used to supply the VLM surfaces in VSPAERO, a stick representation may be used for a structural analysis, and the points representation may supply mass and inertia to a dynamics simulation. OpenVSP’s DegenGeom tool produces a file with each level of degeneracy and all relevant metadata for the model.
