COMSOL Multiphysics is a finite element analyzer, solver, and simulation software package for various physics and engineering applications, especially coupled phenomena and multiphysics.
Computers are used to perform the calculations required to simulate the free-stream flow of the fluid, and the interaction of the fluid (liquids and gases) with surfaces defined by boundary conditions. With high-speed supercomputers, better solutions can be achieved, and are often required to solve the largest and most complex problems.
LS-DYNA consists of a single executable file and is entirely command-line driven. Therefore, all that is required to run LS-DYNA (besides some licensing infrastructure) is a command shell, the appropriate executable for the computer's architecture, an input file, and enough free disk space to store the results.
Free-form deformation (FFD) extensions, including Bézier curves and improved usability. Reorganization of the incompressible solver for future expansion. Harmonic Balance flow analysis capability. Algebraic transition model implementation. More and better boundary conditions (accuracy and convergence improvements).
In computational fluid dynamics (CFD), the SIMPLE algorithm is a widely used numerical procedure to solve the Navier–Stokes equations. SIMPLE is an acronym for Semi-Implicit Method for Pressure Linked Equations.
Unlike earlier turbulence models, k-ε model focuses on the mechanisms that affect the turbulent kinetic energy. The mixing length model lacks this kind of generality. [2] The underlying assumption of this model is that the turbulent viscosity is isotropic, in other words, the ratio between Reynolds stress and mean rate of deformations is the same in all directions.
