Ansys FENSAP-ICE Aircraft Icing Getting Started

Course Overview

This course teaches the essential skills you will need to perform aircraft icing, anti-icing and de-icing simulations using Ansys FENSAP-ICE. Hands-on workshops cover every aspect of conducting these simulations, from creating project folders, that will allow you to organize and methodically study a wide variety of in-flight icing conditions, to analyzing the performance of a bleed-air system that prevents ice formation on the leading edge of an aircraft component. In this manner, Course Modules 01 through 05 are constructed to progressively acquire aircraft icing simulation skills using modules and workflows of Ansys FENSAP-ICE. Course Modules 06 to 08 complement the above by providing guidelines on mesh creation, how to use Ansys Fluent with Ansys FENSAP-ICE, and some fundamentals regarding the physics of in-flight icing. 


  • A technical education and background in fluid dynamics and heat transfer is recommended. 
  • An engineering degree is encouraged but not required.


Teaching Method

Lectures and workshops (computer practical sessions) to validate acquired knowledge. Workshops cover the most common in-flight icing environments and types of IPS (ice protection systems).

Learning Outcome

Following completion of this course, you will be able to:

  • Understand the quasi-steady approach of Ansys FENSAP-ICE to simulate ice accretion over aircraft components
  • Learn how to account for different in-flight icing environments, Appendix C, D and O, and particle (droplets & crystals) distributions using Ansys FENSAP-ICE.
  • Learn how to conduct conjugate heat transfer simulations with Ansys FENSAP-ICE to evaluate the performance of bleed-air and electro-thermal ice protection systems.
