Multiphysics Simulation with Ansys Mechanical
Understanding and mastering strongly coupled physical phenomena
In this training, you will learn about the theory and practical application of coupled field simulation for the interaction of mechanics, temperature and electricity. This training is offered as a 2-day course.
Duration
2 days
Prerequisites
Basic knowledge of Ansys Mechanical
Software used
Ansys Mechanical
- Introduction to strong and weak coupling
- Field coupling in the blink of an eye with the Coupled-Field-Block
- Bidirectional and multidirectional coupling of electrics, thermals, mechanics, etc.
- Strengthening and damping interactions while considering nonlinearities
Description
Many simulations today are still carried out within a single physical subdomain. This is acceptable if a mutual influence with the other subdomains is negligible. However, questions concerning the consideration of these interactions can only be answered inadequately by analytical methods. Typical applications are connectors and micro-electro-mechanical systems (MEMS). Multiphysics FEM simulations can be used for the design of these applications. Ansys offers excellent tools for this purpose and calculates the resulting effects, taking nonlinear material dependencies into account.
An electric current produces losses and as a result causes heating, which leads to mechanical strain. This, in turn, can influence the course of the electric current. For connectors and MEMS, all these effects are relevant. Physical interactions are also relevant in many other applications. This training will illustrate the possibilities for simulative analysis of these systems.
This training is aimed at users and developers of connectors, MEMS and similar systems who want to understand and improve their process and shorten the development time for future processes.
