Training eLearning Advanced

Learn how to perform thermal analyses in Ansys Mechanical: best practice for heating and cooling tasks and determination of thermal stresses. This training is offered as a 3-day course or alternatively as a self-paced eLearning course.

3 days

Basic knowledge of Ansys Mechanical

Software used
Ansys Mechanical

  • Efficient mapping of heat conduction, convection and radiation
  • Simulate transient heating and cooling processes yourself
  • Coupling to flow, structural and electromagnetic simulations
  • Independent, targeted planning of thermal analyses


Temperature changes significantly influence product behavior and can reduce the life cycle. They alter material properties and cause thermal distortion of assemblies. Thermal simulations with Ansys Mechanical can answer many technical questions. With how much power can I operate my engine without it overheating? What additional stress is my structure subjected to at high or low operating temperatures? How should I dimension my heating or cooling system? Where do I need to use expensive high-temperature materials? How quickly will my apparatus heat up to operating temperature?

You will be able to solve heat transfer tasks using conduction, convection, and radiation. You will also learn how to model transient processes including phase transitions. Using examples, you will learn about coupling to other types of analysis, how convective boundary conditions can be taken from a flow analysis, how the temperature field can be transferred as a load into a deformation analysis, and how the effects of electrical-thermal interactions can be studied. This training is aimed at all development engineers, test engineers, and project managers who want to perform temperature tasks beyond testing, analytical estimations, or network abstractions using 3D field simulation with Ansys Mechanical. You will be able to make reliable predictions at an early stage of development.

Do you have questions on the training or the eLearning?

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). 

Can I test the eLearning offer without obligation?

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.

How much time should I allow for an 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.

For how long can I access the learning content?

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.
