open source software
To support research in the 2006-2008 NFFP project DirSim, a surface modeling tool and mesh generator (sumo) and a visualization program (scope) were developed. In 2008, the EU project SimSAC sponsored further improvement of sumo. Both programs are open source software distributed under the terms of the GPL, v2.
modeling and mesh generation
The surface modeler sumo is a graphical tool aimed at rapid creation of aircraft geometries and automatic surface mesh generation. Sumo is not a CAD system, but rather a easy-to-use sketchpad, highly specialized towards aircraft configurations. Read more...
visualization for aeroelasticity
Scope is a visualization program to display results generated by the potential flow solver dwfs, such as surface data, flutter modeshapes and flight trajectories. Furthermore, it can read NASTRAN bulk data files as well as modal analysis results and animate eigenmode shapes. Read more...
