The Software Mechanical Engineers Use the Most

Here is a list of software generally used by mechanical engineers. This list may not be exhaustive, since there is a huge amount of software on the market and every company’s toolkit needs can be different.

Design

Every mechanical engineer is expected to have a solid grasp of design. It’s used heavily in most fields such as Automotive Engineering, Aerospace Engineering, and Tool Design. It’s also becoming more visible to the outside world with the advancement of Rapid Prototyping and 3D Printing.

AutoCAD

website: AutoCAD / AutoCAD has a user-friendly interface and includes many tools for designing complex parts in 2D and 3D. Files can be exported to CAM software for analysis.

AutoCAD has commands like create, edit, polylines, trim curve, and many more that you’ll use.

SolidWorks

website: SolidWorks / General-purpose CAD software with a user-friendly interface for creating 2D and 3D parts.

SolidWorks is a 3D mechanical Computer-Aided Design (CAD) program or application software that runs on Microsoft Windows.

Pro/Engineer Wildfire and Creo Parametric

Software with advanced features and tools for design, drafting, assembly, welding, drawings, etc.

CATIA

website: CATIA / CATIA is an acronym for “Computer Aided Three-dimensional Interactive Application.”

It’s a multi-platform commercial CAD/CAM/CAE software suite developed by the French company Dassault Systèmes. CATIA is often referred to as a 3D product lifecycle management software suite. Style and shape design, mechanical design, and equipment and systems engineering, management of digital mockups, machining, analysis, and simulation.

software preferred by mechanical engineers CATIA

CATIA enables the creation of 3D parts, from 3D sketches, sheet metal, composites, molded, forged, or tooled parts, all the way to the definition of mechanical assemblies.

Most aerospace companies used CATIA software to design their aircraft.

NX Unigraphics

website: SIEMENS NX. / Formerly known as NX Unigraphics, or often just UG, NX is an advanced high-end CAD/CAM/CAE software suite originally developed by Unigraphics, but developed by Siemens PLM Software since 2007.

which programs do mechanical engineers use Siemens NX

Among other tasks, it’s used for:

Design (parametric and direct solid/surface modeling)
Engineering analysis (static, dynamic, electromagnetic, thermal, using the Finite Element Method, and fluid using the finite volume method). Manufacturing of the finished design using the included machining modules.

Autodesk 3ds Max

Autodesk 3ds Max is primarily a 3D modeling software with additional features for animation. These features make it suitable for games and films. The software is especially useful for animating mechanical parts.

ANSYS Use Case

ANSYS is considered the industry standard for structural, thermal, and fluid simulations using finite element analysis (FEA).

SolidWorks Simulation

SolidWorks Simulation works integrated with the CAD model, allowing quick stress analyses to be run during the design phase.

Modeling with MATLAB

MATLAB is widely used software for control systems design and data analysis in mechanical engineering.

Structural Analysis Programs

ANSYS

A CAD analysis software suite for multiple tests, showing results in green, blue, and red. The software calculates stress values in various sections (allowing advanced optimization). The Finite Element Method (FEA) is one of the numerical methods mostly concerned with finding approximate numerical solutions to problems in science, such as structural, fluid, thermal, or fluid-structure interface (FSI) problems.

Ansys Discovery, a complete solution for real-time 3D simulation and analysis
Ansys SpaceClaim, 3D modeling software for creating, editing, and modifying CAD or STL files for design, reverse engineering, simulation, manufacturing, 3D printing, and sheet metal
Ansys Fluent, fluid simulation software known for its advanced physics modeling capabilities and unmatched accuracy
Ansys Motor-CAD, a dedicated electric machine design tool for rapid multiphysics simulation across the full torque-speed operating range
Ansys LS-DYNA, crash simulation software, an explicit dynamics solver that simulates the extreme material deformation response of structures under severe loading periods
Ansys Forte, a computational fluid dynamics (CFD) software tool for modeling internal combustion engines and positive displacement compressors
Ansys Additive Print, for printed-part distortion and stress prediction

MATLAB

MATLAB is primarily an advanced math software (with programming capabilities), but it has features designed specifically for engineering, such as tools for obtaining the stability of an automatic machine.

Programming

C++

C++ is a general-purpose programming language. In addition to low-level memory manipulation capabilities, it has object-oriented, generic, and functional features. It’s almost always implemented as a compiled language, and compilers for it are provided by many vendors, including the Free Software Foundation, LLVM, Microsoft, Intel, Oracle, and IBM, so it’s available on many platforms.

C++ was designed with an orientation toward systems programming and embedded, resource-constrained software and large systems, with performance, efficiency, and flexibility of use as prominent features of its design. C++’s core strengths lie in desktop applications, video games, servers, and performance-critical applications (such as space probes).

Python

Python is an interpreted, high-level, general-purpose programming language. Its language constructs and object-oriented approach aim to help programmers write clear, logical code for small- and large-scale projects.

Python supports multiple programming paradigms, including structured (particularly procedural), object-oriented, and functional programming.

Many operating systems include Python as a standard component. It ships with most Linux distributions, BSD, OpenBSD (as a package), and macOS, and can be used from the command line (terminal). Many Linux distributions use installers written in Python.

Python consistently ranks as one of the most popular programming languages. Python is widely used in AI and machine learning projects with the help of libraries such as TensorFlow, Keras, PyTorch, and Scikit-learn. As a scripting language with a modular architecture, simple syntax, and rich text-processing tools, Python is also often used for natural language processing.
