GASP is AeroSoft's primary software package. GASP is a structured/unstructured, multi-block CFD flow solver which solves the Reynolds Averaged Navier-Stokes (RANS) equations as well as the heat conduction equation for solid bodies. For more information, see the GASP feature list.
GUST is an unstructured CFD flow solver with similar capabilities of GASP. It was first released in 1998 and came with its own grid generator. GUST shared much of the same code as GASP, and was eventually merged into GASP Version 5.0. Because of its merger with GASP, GUST is no longer available as a separate software package.
SENSE was designed as a post-processing tool to GASP with the purpose of determining discrete solutions to the linear sensitivity equations. With SENSE, users of high-order CFD codes can obtain the derivative of the entire flow field with respect to a generic design parameter. Since the sensitivity equations are linear, sensitivity solutions can be obtained in much less time than required by a typical flow solution. SENSE was first released in 1998 as a stand-alone package and was later incorporated into GASP Version v4.2. SENSE is no longer available as a separate software package.
