Ansys CFX Fluid Structure Interaction (FSI) with Ansys Mechanical

Course Overview

The Ansys CFX FSI course is an advanced course covering modeling approaches for fluid-structure interaction applications using Ansys CFX and Ansys Mechanical. The course will cover setup, solution and convergence of one-way and two-way FSI simulations. Students must have experience running Ansys CFX  and some prior experience using Ansys Mechanical for the training to be effective.



  • Completion of the Ansys CFX Getting Started course is required.
  • Experience with Ansys CFX is strongly recommended.
  • Experience with Ansys Mechanical is desirable.

Target Audience: 

Engineers and Designers

Teaching Method: 

Lectures and computer practical sessions to validate acquired knowledge.

Learning pathway


Learning Outcome
