CFD Simulations with Ansys Fluent


Training eLearning Basic

In this course, you will learn the relevant workflows for CFD simulation - from model selection, meshing and calculation to evaluation and quality control. This training is offered as a 3-day course or alternatively as a self-paced eLearning course.

3 days


Software used
Ansys CFD

  • Practical examples of internal and external fluid dynamics
  • Work steps from geometry modeling to setup
  • Systematic evaluation and quality assurance of results
  • Background knowledge and best practice tips for Ansys Fluent


In this introductory training, you will acquire the necessary skills for numerical flow calculations with Ansys Fluent. You will learn to simulate internal and external fluid dynamics with heat transfer and systematically evaluate the results. Quality assurance of the results is also an important part of the training.

The focus is on practical exercises using the Ansys Fluent software. A presentation of the necessary physical and numerical background knowledge accompanies these exercises. You will learn a best practice procedure for carrying out fluid dynamics calculations and apply this in the exercises. After this training, you will be able to carry out CFD simulations independently, from model selection and meshing to calculation, post-processing, and quality assurance.

Do you work in development, calculation, or research? We will show you how you can better understand the fluid dynamics in your productsand develop high-quality products in a time-saving and cost-effective manner. Incorporate the knowledge you have acquired directly into your development and research work and benefit from the many possibilities in Ansys Fluent.

What CADFEM customers are saying

 Sébastien Bernard Design and Project Engineer, Corinthe Ingenierie
Sébastien Bernard
Design and Project Engineer, Corinthe Ingenierie

CADFEM trained us in the use of SpaceClaim and Fluent. The theory-practice-alternation was well balanced, our learning curve was quick and intuitive. The technical mastery and pedagogy are remarkable. After the training, we put in place regular meetings to discuss about our challenges and success. We recommend the CADFEM team without reservation!

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.
