Multiphysics Simulation with Ansys Mechanical

Understanding and mastering strongly coupled physical phenomena


Training Expert

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.

2 days

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


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.

Do you have questions on the training?

When will I receive the final confirmation for my training booking?

Straight after you sign up, an automatic confirmation of receipt will be sent to the email addresses you provided. Once you have successfully verified the data you provided, you will receive your personalized sign-up confirmation, containing further information on course fees, the billing address, etc., by email within two to three working days.  

As soon as the minimum number of attendees has been reached, you will receive a final training confirmation containing further information. If you have booked an on-site training, we recommend that you wait until you have received this final confirmation before booking your travel and accommodation.

If the minimum number of attendees is not reached, we reserve the right to cancel the training seven days before it is due to start at the latest. We are happy to inform you on changing your booking to an alternative date. Please note that we accept no liability for hotel or travel bookings that attendees have already made.

When is the sign-up deadline for a training?

Training places will generally be allocated based on the order in which attendees sign up. For this reason, we always recommend booking for your desired date as early as possible.

As long as a coures still has free places, it can be booked.

At what time do the training courses begin and end?

Usually the training courses start at 9:00 am and end at 5:00 pm of the respective local time. The actual course times will be stated in the booking confirmation. Please note that, depending on the training host, there may be a possible time shift between your and the provider's local time. Therefore all local times are provided with the valid time shift to Greenwich Mean Time (GMT).
