Elevate Your FEA Knowledge


  • The course is completely software independent.
  • All the FEA concepts are illustrated with simple examples.
  • FEA Academy will issue a certificate of completion to each registrant.
  • Ask your questions during the Q&A sessions which will take place during the live lectures. If you prefer, send you questions to your tutor after the live lectures and/or after watching at the replays.

Registration will Open in August 2022

Improve Your Versatility

FEA is so flexible that it can be used in various applications. An engineer with very good knowledge of FEA is much more versatile than one who does not know it well. Since the modeling techniques are universal, mastering FEA will permit you to navigate various types of industries and work on diverse projects.

Expand Your Career Opportunities

Learning FEA in detail permits you expanding your career oppotunities and gives you an edge over other engineers who don't know the good modeling practices.
