ANSYS: US-based and -developed full CAE software package: Ansys Inc. 2022 R2: 2022-07-28: Proprietary commercial software: Free student version available, up to 32,000 nodes/elements [9] Windows, Linux: COMSOL Multiphysics: COMSOL Multiphysics Finite Element Analysis Software (formerly FEMLAB) COMSOL Inc. 6.1: 2022-11-01: Proprietary EULA
Ansys also added parallel processing support for PCs with multiple processors. [15] The educational product Ansys/ed was introduced in 1998. [3] Version 6.0 of the main Ansys product was released in December 2001. [3] Version 6.0 made large-scale modeling practical for the first time, but many users were frustrated by a new blue user interface. [3]
COMSOL Multiphysics is a finite element analyzer, solver, and simulation software package for various physics and engineering applications, especially coupled phenomena and multiphysics.
LS-DYNA originated from the 3D FEA program DYNA3D, developed by Dr. John O. Hallquist at Lawrence Livermore National Laboratory (LLNL) in 1976. [4] DYNA3D was created in order to simulate the impact of the Full Fuzing Option (FUFO) or "Dial-a-yield" nuclear bomb for low altitude release (impact velocity of ~ 40 m/s).
Ansys HFSS (high-frequency structure simulator) is a commercial finite element method solver for electromagnetic (EM) structures from Ansys. [ 1 ] Engineers use Ansys HFSS primarily to design and simulate high-speed, high-frequency electronics in radar systems, communication systems, satellites, ADAS, microchips, printed circuit boards, IoT ...
The following two problems demonstrate the finite element method. P1 is a one-dimensional problem : {″ = (,), = =, where is given, is an unknown function of , and ″ is the second derivative of with respect to .
FEATool Multiphysics is a fully integrated physics and PDE simulation environment where the modeling process is subdivided into six steps; preprocessing (CAD and geometry modeling), mesh and grid generation, physics and PDE specification, boundary condition specification, solution, and postprocessing and visualization.
Systems Tool Kit (formerly Satellite Tool Kit), often referred to by its initials STK, is a multi-physics software application from Analytical Graphics, Inc. (an Ansys company) that enables engineers and scientists to perform complex analyses of ground, sea, air, and space platforms, and to share results in one integrated environment. [1]
