High Performance Software


GASP is a structured, multiblock CFD flow solver that solves the Reynolds Averaged Navier-Stokes (RANS) equations. It is applicable to compressible flow fields approximately Mach 0.1 and greater. 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 includes physical modeling to enable the simulation of chemical laser power generation as well as the external flow fields found in atmospheric flight. GASP is uniquely suited to efficiently and accurately model the internal flow fields of chemical lasers. GASP includes specialized physical models for the chemical reactions, mixing, and boundary conditions of COIL and HF lasers. GASP also includes power extraction for a stable resonator using geometric ray tracing.
