Computer-aided design (CAD) is the use of computers to aid in the creation, modification, analysis, or optimization of a design. This software is used to increase the productivity of the designer, improve the quality of design, improve communications through documentation, and to create a database for manufacturing. Designs made through CAD software help protect products and inventions when used in patent applications. CAD output is often in the form of electronic files for print, machining, or other manufacturing operations. The terms computer-aided drafting (CAD) and computer-aided design and drafting (CADD) are also used.
Creo Parametric, formerly known, together with Creo Elements/Pro, as Pro/Engineer and Wildfire, is a solid modeling or CAD, CAM, CAE, and associative 3D modeling application, running on Microsoft Windows.
Computer-aided engineering (CAE) is the general usage of technology to aid in tasks related to engineering analysis. Any use of technology to solve or assist engineering issues falls under this umbrella.
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.
SDRC is a leading company specializing in MCAE and PLM software.
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, and the in-house brands NEi Nastran in-CAD, NEi Fusion, and NEi Works for SolidWorks. This software was acquired by Autodesk in May 2014.
Solid Edge is a 3D CAD, parametric feature and synchronous technology solid modeling software. It runs on Microsoft Windows and provides solid modeling, assembly modelling and 2D orthographic view functionality for mechanical designers. Through third party applications it has links to many other Product Lifecycle Management (PLM) technologies.
NEi Software, founded as Noran Engineering, Inc. in 1991, is an engineering software company that develops, publishes and promotes FEA software programs including its flagship product NEi Nastran. The FEA algorithms allow engineers to analyze how a structure will behave under a variety of conditions. The types of analysis include linear and nonlinear stress, dynamic, and heat transfer analysis. MCT, PPFA, dynamic design analysis method, optimization, fatigue, CFD and event simulation are just some of the specialized types of analysis supported by the company.
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.
CD-adapco was a multinational computer software company that authored and distributed applications used for computer-aided engineering, best known for its computational fluid dynamics (CFD) products. In 2016 the company was acquired by Siemens Digital Industries Software.
ADINA is a commercial engineering simulation software program that is developed and distributed worldwide by ADINA R & D, Inc. The company was founded in 1986 by Dr. Klaus-Jürgen Bathe, and is headquartered in Watertown, Massachusetts, United States. On April 7, 2022, Bentley Systems acquired ADINA R&D, Inc.
I-DEAS, a computer-aided design software package. It was originally produced by SDRC in 1982. I-DEAS was used primarily in the automotive industry, most notably by Ford Motor Company and by General Motors. SDRC was bought in 2001 by its competitor, Electronic Data Systems, which had also acquired UGS Corp.. EDS merged these two products into NX. UGS was purchased by Siemens AG in May 2007, and was renamed Siemens PLM Software, now known as Siemens Digital Industries Software.
NX, formerly known as "Unigraphics", is an advanced high-end CAD/CAM/CAE, which has been owned since 2007 by Siemens Digital Industries Software. In 2000, Unigraphics purchased SDRC I-DEAS and began an effort to integrate aspects of both software packages into a single product which became Unigraphics NX or NX.
FEMtools is a multi-functional, cross-platform and solver-independent family of CAE software programs providing analysis and scripting solutions for many different types of engineering simulation applications. The program is developed, supported and licensed by Dynamic Design Solutions ("DDS") NV, located in Leuven, Belgium.
UGS was a computer software company headquartered in Plano, Texas, specializing in 3D & 2D Product Lifecycle Management (PLM) software. Its operations were amalgamated into the Siemens Digital Industries Software business unit of Siemens Industry Automation division, when Siemens completed the US$3.5 billion acquisition of UGS on May 7, 2007.
Siemens Digital Industries Software is an American computer software company specializing in 3D & 2D Product Lifecycle Management (PLM) software. The company is a business unit of Siemens, operates under the legal name of Siemens Industry Software Inc, and is headquartered in Plano, Texas.
