NISA/3D-FLUID

NISA/3D-FLUID is used for analyzing 3D incompressible and 3D compressible fluid flow like steady/transient, laminar/turbulent, Newtonian/non-Newtonian, free surface, potential, subsonic/transonic/hypersonic, inviscid/viscous, combustion simulations, and chemically reacting flows with mixing. Fluid dynamics capabilities of NISA are used across analysis such as electromagnetic, fluid-structure interaction, heat, civil and PCB analysis. A direct interface between NISA/3D-FLUID and NISA II (structures) is available.
