Higher Fidelity Designs for the Aerospace Industry with Fluid-Thermal Structural Interaction (FTSI)

Course Overview

The current trends in the Aerospace and Defense industry are accelerating the existing focus on environmental sustainability, performance improvement, safety enhancements, and reduction in costs and time. All of these are complex initiatives that require competing design and business priorities to fit together seamlessly. Designing with close performance margins and balancing functional requirements with material and production costs requires uncompromised understanding of the physics involved. In other words, the closer the design comes to optimal design, the more important capturing all the physics with high fidelity becomes. Simulation complements the design process all the way from conceptual stage to assessing the performance in operation. The journey of pervasive simulation starts with a single physics but does not stop there. As complexity grows and the design envelope narrows, companies start the journey onto more complex simulation strategies – into Multiple physics and then into Multiphysics. Multiphysics modeling can have many flavors and many possible couplings of physics areas.

This course will focus on modeling techniques for high fidelity Fluid Thermal-Structure interactions (FTSI) with several use cases that are relevant to the A&D industry space.  Ansys CFD software will be used in this course to illustrate example models. The course content will focus on generalized physical principles that are applicable to all types of CFD and Structural solvers regardless of your software tool of choice.


  • This course is intended for engineers and physicists at all levels of expertise interested in modeling real-life FTSI problems.
  • A basic knowledge of the subject is required.
