Computational Mechanics 

Southwest Research Institute® (SwRI®) develops and applies state-of-the-art computational tools using large-scale numerical simulations to solve a broad range of client problems. Tools include hydrocodes, engineering codes, and computational fluid dynamics (CFD) codes. The SwRI Computational Mechanics Section technical staff has expertise in structured and unstructured grid solvers using either finite volume or finite element methods. The Section maintains a large suite of codes for simulating compressible or incompressible flows, structural response and deformation, thermal and chemical reaction effects, and other complex physics such as turbulence modeling.
