Comp Geom Introduction and Use


The Comp Geom tool is a geometry intersection and analysis algorithm that will compute the theoretical and wetted areas and volumes of your OpenVSP model, producing an intersected triangulated mesh. Comp Geom is widely integrated into other analyses and functions within OpenVSP such as VSPAERO’s Panel mode and the Parasite Drag tool.

Component subsurfaces may be included in the analysis to separate regions of a body or wing. A semi-span or half-mesh model may be generated normal to the XZ plane, if desired.

Users may choose between the “Normal” set, which analyzes the geometry surfaces as thick bodies, or the “Degen” set, which degenerates the included components to their camber surface representation before analyzing as thin surfaces. This enables the generation of hybrid thick/thin meshes.
