LS-DYNA is an advanced general-purpose multiphysics simulation software package developed by the former Livermore Software Technology Corporation (LSTC), which was acquired by Ansys in 2019. While the package continues to contain more and more possibilities for the calculation of many complex, real world problems, its origins and core-competency lie in highly nonlinear transient dynamic finite element analysis (FEA) using explicit time integration. LS-DYNA is used by the automobile, aerospace, construction and civil engineering, military, manufacturing, and bioengineering industries.
NASTRAN is a finite element analysis (FEA) program that was originally developed for NASA in the late 1960s under United States government funding for the aerospace industry. The MacNeal-Schwendler Corporation (MSC) was one of the principal and original developers of the publicly available NASTRAN code. NASTRAN source code is integrated in a number of different software packages, which are distributed by a range of companies.

NEi Nastran was an engineering analysis and simulation software product of NEi Software Based on NASA's Structural Analysis program NASTRAN, the software is a finite element analysis (FEA) solver used to generate solutions for linear and nonlinear stress, dynamics, and heat transfer characteristics of structures and mechanical components. NEi Nastran software is used with all major industry pre and post processors including Femap, a product of Siemens PLM Software, in house brands NEi Nastran in-CAD, NEi Fusion, and NEi Works for SolidWorks. This software was acquired by Autodesk in May 2014.
The spatial twist continuum is a dual representation of an all hexahedral mesh that defines the global connectivity constraint.
Femap is an engineering analysis program sold by Siemens PLM Software that is used to build finite element models of complex engineering problems ("pre-processing") and view solution results ("post-processing"). It runs on Microsoft Windows and provides CAD import, modeling and meshing tools to create a finite element model, as well as postprocessing functionality that allows mechanical engineers to interpret analysis results. The finite element method allows engineers to virtually model components, assemblies, or systems to determine behavior under a given set of boundary conditions, and is typically used in the design process to reduce costly prototyping and testing, evaluate differing designs and materials, and for structural optimization to reduce weight.
Z88 is a software package for the finite element method (FEM) and topology optimization. A team led by Frank Rieg at the University of Bayreuth started development in 1985 and now the software is used by several universities, as well as small and medium-sized enterprises. Z88 is capable of calculating two and three dimensional element types with a linear approach. The software package contains several solvers and two post-processors and is available for Microsoft Windows, Mac OS X and Unix/Linux computers in 32-bit and 64-bit versions. Benchmark tests conducted in 2007 showed a performance on par with commercial software.
NEi Fusion is a finite element analysis program sold by NEi Software that is used by engineers to build and analyze 3D models of parts and assemblies of various products. NEi Fusion digital-simulation software virtually applies forces, pressures, vibration, acceleration loads, or thermal conditions to 3D models of parts, structures, and assemblies. It obtains results of various engineering parameters, such as deformation, stresses, strains, temperature distributions, and modal shapes the design would experience if implemented. The results, which range from tables of data to contour plots and animations, provide engineering insight. For example, result visualizations like color-coded, contour plots can help deepen understanding of physical phenomena in complex geometry. NEi Fusion consists of a 3D parametric CAD modeler powered by SolidWorks with NEi Nastran finite element analysis solvers. NEi Fusion runs on Microsoft Windows and provides CAD modeling, import and meshing tools.
