Computer-aided engineering (CAE) is the use of computer software to simulate performance in order to improve product designs or assist in the resolution of engineering problems for a wide range of industries. This includes simulation, validation, and optimization of products, processes, and manufacturing tools.
A typical CAE process comprises of pre-processing, solving, and post processing steps. In the pre-processing phase, engineers model the geometry (or a system representation) and the physical properties of the design, as well as the environment in the form of applied loads or constraints. Next, the model is solved using an appropriate mathematical formulation of the underlying physics. In the post-processing phase, the results are presented to the engineer for review.
Industrial-strength productivity where CAE results are “current and in the design loop”. Siemens CAE provides open support for industry standard CAD and CAE data exchange formats: Parasolid, IGES, STEP, STL, UNV, NBD, XML; standard 3rd party CAE software integrations including ANSYS, ABAQUS, LS-Dyna and MSC NASTRAN; and customizability for in-house solutions.

The benefits of CAE
- Design decisions can be made based on their impact on performance.
- Reduced product development cost and time, with improved product quality and durability.
- CAE can provide performance insights earlier in the development process, when design changes are less expensive to make.
- CAE helps engineering teams manage risk and understand the performance implications of their designs.
- Integrated CAE data and process management extends the ability to effectively leverage performance insights and improve designs to a broader community.
- Warranty exposure is reduced by identifying and eliminating potential problems. When properly integrated into product and manufacturing development, CAE can enable earlier problem resolution, which can dramatically reduce the costs associated with the product lifecycle.
