Basic Features

• Solves the three-dimensional continuous sensitivity equations for inviscid, laminar and/or chemically-reacting flows
• Accommodates any compressible-flow CFD solver (commercial, government, academic or personal) which can generate Plot3D grid and solution formats
• Source code from the flow solver is not required, making SENSE compatible with solvers from any commercial vendor
• In many cases, sensitivity solutions are obtained in less than 20% of the CPU time for a flow solution
• Provides flow sensitivities for both flow-related and geometric design variables
• Provides linear approximation to near-by flow fields for accurate and fast re-analysis
• Automatic generation of zonal boundaries, sequence levels, and solver input file given a Plot3D grid
• Supports one-to-one abutting zones
• Provides sensitivity derivatives for finite-rate or frozen chemical mixtures
