Description
Contact calculations are a central part of simulation tasks in engineering. They enable the interaction of components within an assembly. A powerful tool for this task is Ansys Mechanical, which is often used to represent non-linearities in structural mechanics simulations. Contact modeling can appear complex due to the multitude of setting options and the goal of achieving a certain mechanical behavior in the contact zone. Factors such as numerical robustness, solution convergence, and result quality play a crucial role here.
The global stiffness behavior of the design is greatly influenced by the contact. Therefore, it is important to accurately determine the contact pressure and consider the role of penetration and contact stiffness. The choice of the right contact algorithm can be decisive. After this training in Ansys Mechanical, you will be able to calculate assemblies taking into account linear and non-linear contacts. You will also be able to critically evaluate the solution behavior and, if necessary, react appropriately by overriding the default settings. This will enable you to reliably manage contact calculations and achieve high-quality results. This knowledge is particularly valuable for design engineers, calculation engineers, and other simulation users.

What CADFEM customers are saying
Do you have questions on the training or the eLearning?
If you book through your university, you will receive a 50% discount on the stated fee on training courses and eLearning courses.
For more information on the validity and how booking with the code ACADEMIC50 works, please visit our page on training for academic users.
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.
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).
To get a clear impression of our online learning format, we offer you a trial allowing you access to the starting module of an eLearning course of your choice. No costs, no cancellation period or anything similar. Moreover, with this free test access you can check all the technical requirements for a smooth learning process. You can easily request the free module from any eLearning course.
Each online course day comprises four eLearning modules. You should ideally allow 90 to 120 minutes of uninterrupted learning time for each module. This will allow you to acquire the knowledge provided by a module and to consolidate it through quiz questions and Ansys exercises. By dividing each module into micro learning units, you can also make good use of smaller time windows, such as on your commute.
Prerequisite for the use of the eLearning courses is the use of a personalized access to the CADFEM learning platform. When purchasing an eLearning course, access to the learning platform is 365 days. As a subscription user, access to the learning platform starts and ends with the start and end of the flat rate. With the start of a further learning product (Learning Subscription, training, eLearning), access to your content is extended by 365 days.
