Simulation / CAE
Simulation covers the broad area of computer aided tools typically called CAE (computer aided engineering) which include stress analysis on components and assemblies (FEA), thermal and fluid flow analysis (CFD), motion simulation (kinematics), various process analyses such as mold flow or die press forming,optimizations of many kinds and many more highly specialized tools and methods to simulate a product's performance, behavior and reliability.
Simulation speeds time to market, lowers costs and reduces product failures. Although computer simulation was once the domain of aerospace and automotive manufacturers, virtually all product design companies today can benefit greatly from applying the right computer simulations during their product development process.
The CAE Process
A typical CAE process comprises of pre-processing, solving, and post-processing steps. In the pre-processing phase, engineers model the geometry 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.
CAE applications support a wide range of engineering disciplines or phenomena including:
- Stress and dynamics analysis on components and assemblies using finite element analysis (FEA)
- Thermal and fluid analysis using computational fluid dynamics (CFD)
- Kinematics and dynamic analysis of mechanisms (multibody dynamics)
- Mechanical event simulation (MES)
- Control systems analysis
- Simulation of manufacturing processes like casting, molding and die press forming
- Optimization of the product or process
Some engineering problems require the simulation of multiple phenomena in order to represent the underlying physics. CAE applications that address such problems are often called multi-physics solutions.
Benefits of CAE
- The benefits of CAE include reduced product development cost and time, with improved product quality and durability.
- Design decisions can be made based on their impact on performance.
- Designs can be evaluated and refined using computer simulations rather than physical prototype testing, saving money and time.
- 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.
