What is Digital Engineering?

Digital engineering is an engineering approach that uses digital models, data, software, simulation and computational tools to support the design, development, manufacture, operation and maintenance of engineered systems.

It brings together traditional engineering disciplines with information technology, data science, systems engineering, artificial intelligence and advanced manufacturing.

The Digital Engineering Concept

Requirements → Digital Models → Simulation → Manufacture → Operation → Data → Improved Design

The central idea is to create a connected digital representation of an engineering system so that information can flow between design, analysis, manufacturing and operation.

The site www.engineering.me.uk provides a general resource on Engineering.

Digital engineering attempts to maintain consistency and traceability of engineering information throughout the lifecycle rather than treating design, analysis, manufacturing and operation as isolated activities.

Computer-Aided Design

CAD provides the digital foundation for much modern engineering design. Engineers can create three-dimensional models, assemblies, drawings and detailed product definitions.

The LinkedIn Group CAD CAM CAE has been created to connect the people interested in the CAD CAM CAE field. You can also link to the LinkedIn profile CAD CAM CAE.

3D Modelling
