NEi Nastran is an engineering analysis and simulation software product of NEi Software (formerly known as Noran Engineering, Inc.) 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.
Computer-aided engineering (CAE) is the broad usage of computer software to aid in engineering analysis tasks.
 It includes finite element analysis (FEA) , computational fluid dynamics (CFD) , multibody dynamics (MBD) , and optimization.
Femap ("Finite Element Modeling And Postprocessing") 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.
Southpointe is a 589 acre suburban business park located in Cecil Township near Canonsburg, Pennsylvania, south of Pittsburgh and is a familiar landmark along Interstate 79.
 It is home to many corporations, including Fortune 500 members CONSOL Energy and Mylan as well as ANSYS, Inc..
In numerical analysis, the mixed finite element method, also known as the hybrid finite element method, is a type of finite element method in which extra independent variables are introduced as nodal variables during the discretization of a partial differential equation problem.
 The extra independent variables are constrained by using Lagrange multipliers.
 To be distinguished from the mixed finite element method, usual finite element methods that do not introduce such extra independent variables are also called irreducible finite element methods.
 The mixed finite element method is efficient for some problems that would be numerically ill-posed if discretized by using the irreducible finite element method; one example of such problems is to compute the stress and strain fields in an almost incompressible elastic body.
ANSYS, Inc. is an American Computer-aided engineering software developer headquartered south of Pittsburgh in Cecil Township, Pennsylvania, United States.
 Ansys publishes engineering analysis software across a range of disciplines including finite element analysis, structural analysis, computational fluid dynamics, explicit and implicit methods, and heat transfer.
Kimeme is an open platform for multi-objective optimization and multidisciplinary design optimization.
 It is intended to be coupled with external numerical software such as Computer Aided Design (CAD), Finite Element Analysis (FEM), Structural analysis and Computational Fluid Dynamics tools.
 It has been developed by Cyber Dyne Srl and provides both a design environment for problem definition and analysis and a software network infrastructure to distribute the computational load.
The Wood–Armer method is a structural analysis method based on finite element analysis used to design the reinforcement for concrete slabs.
 This method provides simple equations to design a concrete slab based on the output from a finite element analysis software.
VisualFEA is a finite element analysis program running on MS Windows and Mac OS X platforms.
 The program is being developed and distributed by Intuition Software, Inc. in South Korea, and is used chiefly for structural and geotechnical analysis.
 The strongest point of the program is its intuitive and user-friendly usage based on graphical pre- and postprocessing capabilities.
 VisualFEA has educational functions for teaching and learning structural mechanics and finite element analysis through graphical simulation.
 Thus, this program is widely used in college courses related to structural mechanics and finite element method.
The finite element method (FEM) is a numerical method for solving problems of engineering and mathematical physics.
 It is also referred to as finite element analysis (FEA).
 Typical problem areas of interest include structural analysis, heat transfer, fluid flow, mass transport, and electromagnetic potential.
 The analytical solution of these problems generally require the solution to boundary value problems for partial differential equations.
 The finite element method formulation of the problem results in a system of algebraic equations.
 The method yields approximate values of the unknowns at discrete number of points over the domain.
 To solve the problem, it subdivides a large problem into smaller, simpler parts that are called finite elements.
 The simple equations that model these finite elements are then assembled into a larger system of equations that models the entire problem.
 FEM then uses variational methods from the calculus of variations to approximate a solution by minimizing an associated error function.
