GASP is a structured, multi-block CFD flow solver which solves the Reynolds Averaged Navier-Stokes (RANS) equations. It is applicable to compressible flow fields approximately Mach 0.1 and greater, as well as incompressible flows. This would include flows with finite-rate or equilibrium chemistry, such as combustion problems or reentry type flows. GASP can perform both steady and time accurate simulations. The code has a 6 degree of freedom (6-dof) motion modeling capability and uses a Chimera overlapping grid system for moving body simulations. Overlapping grids may also be used for complex steady state simulations. GASP is our most stable, and validated product.

GUST , in a nutshell is an unstructured version of GASP. It too is a compressible CFD flow solver for anything from perfect gas calculations up to finite-rate chemistry, with non-equilibrium thermodynamics (like GASP). However, GUST operates on unstructured, or arbitrary control volumes. Currently the grid generators that interface with GUST generate tetrahedra, pyramids, prisms, and hexahedra (brick element). So, you can run on a GASP type structured grid, but also more grid types.

SENSE takes a user supplied structured multi-block cfd solution, and will predict the variation about that solution with respect to one or more design variables. For example, it will tell you how the entire solution at a point will vary as you change the angle of attack. SENSE is not meant to replace a CFD solver, but to augment it.
