Ansys Lumerical FEEM
Getting Started (Self-paced Learning Available)

Course Overview

This course introduces the Finite Element Eigenmode (FEEM) Solver available in the finite-element IDE. It is primarily intended for beginner to intermediate users, with a focus on providing practical examples to common tasks. The course covers frequently used functional areas, simulation setup, running simulations, and visualizing results.


  • Basic knowledge about electromagnetism and mode propagation theory
  • Familiarity with the finite element design environment and simulation workflow is recommended. This course does not cover object modeling and structure building tips. These skills can be obtained in a related course such as DGTD Getting Started. 

Teaching Method

Lectures and demos. A major emphasis is placed on balanced mix of basic theoretical knowledge and helpful practical examples that will allow new users to quickly become proficient and productive with FDE.

Learning Outcome

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

  • Describe the algorithm used by the FEEM solver.
  • Know various application areas and example devices where the FEEM solver can be used.
  • Know how the effective index and loss are obtained from the eigenvalue problem.
  • Familiarize yourself with the main FEEM Solver settings.
  • Understand the (n,k) Material Attribute and how to set it up.
