 When CompGeom is executed, it can produce a wetted area/volume report file in a comma-delimited spreadsheet ready file as CompGeom.csv. ​ This file contains the same information as CompGeom.txt. ​ An example of this file for a simple model is included below. ​ The theoretical areas and volumes are the untrimmed values for each component. ​ The Wetted areas and volumes are the trimmed values for each component. When CompGeom is executed, it can produce a wetted area/volume report file in a comma-delimited spreadsheet ready file as CompGeom.csv. ​ This file contains the same information as CompGeom.txt. ​ An example of this file for a simple model is included below. ​ The theoretical areas and volumes are the untrimmed values for each component. ​ The Wetted areas and volumes are the trimmed values for each component.

 +When DegenGeom is executed, it can produce a coordinate definitions file of degenerate geometries like the surface, plate, stick and point models as detailed [[http://​www.openvsp.org/​wiki/​lib/​exe/​fetch.php?​media=degen_geom.pdf|here]]. Panel and wing camber surface coordinates,​ panel areas, and similar information are available. This ASCII file can be opened using Excel or editors like Notepad++ and may also be parsed for discretization of geometries in several different physical applications such as Euler-Bernoulli beam theory and vortex lattice solvers. This file contains the same information as DegenGeom.m.
