NISA/3D Fluid

NISA/3D-FLUID is a general purpose finite element-based, fluid dynamics program for analyzing fluid flow and heat transfer problems for both compressible and incompressible flows. Fluid-Solid interaction involving flow and conjugate heat transfer is available. Pressure loading due to fluid flow can be applied for stress analysis in solids. A direct interface between NISA/3D-FLUID and NISA II (structures) is also available.
