Ansys for Students: Flow Simulation with Ansys Fluent

Perform CFD calculations in a practical and professional manner


eLearning Basic

How do I set up a professional CFD workflow with model selection, meshing, calculation, and evaluation? This training is offered as a self-paced eLearning course, in which you should invest a total of 2 working day(s) with your own time allocation.

2 days


Software used
Ansys CFD

  • Quick introduction to the professional FE software Ansys Fluent
  • Benefit from practical examples for internal and external flows
  • Get to know all working steps, including systematic evaluation
  • Receive valuable background knowledge and best practice tips
  • All tasks can be carried out with the free Ansys Student license


In this course you will learn all the necessary skills to perform computational fluid dynamics (CFD) calculations with Ansys Fluent. Particularly valuable are the practical examples of internal and external flows with heat transfer. They form the focus of the course in conjunction with practical exercises. Project-experienced tutors show you the individual work steps of a professional CFD calculation. Starting with the geometry modeling up to the systematic evaluation and assessment of the results. In addition to the exercises, we provide the necessary background knowledge, as it is sometimes addressed in lectures.

Detailed agenda for this 2-day training

Do I receive a certificate of completion for the courses?

Have you successfully completed a course, i.e., all units, exercises and quizzes? Then the final test will be unlocked for you. Once you have successfully completed it, you will receive a certificate from us by e-mail. You can use this for your application, share it or include it in your network profiles - just as you please.


How can I access the learning videos and tutorials?

A one-time registration under myAccount is necessary. Then, select your first desired course, put it in the shopping cart and submit the booking. For your first order, you will be asked for a valid certificate of enrollment. For further bookings in the same semester, this will not be necessary anymore. You will receive the access data to the CADFEM learning platform on the same or the following workday.

How long can I use the eLearning courses?

Access to your eLearning course is for one year after booking the course and is directly linked to your university email address. 

How do I get the Ansys license for practice?

For practicing you can use the free Ansys Student software. For some of the exercises you will need a license that includes more nodes. Where do you get it? Almost all universities have Ansys licenses that are also available for students. It is best to ask at the computer center of your university.

The eLearning program for students provided me with the necessary basics for CFD simulation for my master's thesis. I particularly liked the combination of theoretical derivation and subsequent application in Ansys. This was the basis for building and evaluating a high-quality simulation model without any previous CFD knowledge.

I am absolutely thrilled! The mixture of background knowledge, practical demonstrations and explanations of application is done very well. Thank you very much for allowing me to use this course free of charge as a student!
