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

Course Overview

This introductory FDTD course is primarily intended for beginner to intermediate users, with the goal of giving users an understanding of the solver physics, simulation workflow and data analysis techniques. Upon completion of all course sections and exercises, you will have the ability to independently setup a simulation and select appropriate settings for common applications. Additionally, the courses provide references to useful Knowledge Base articles for each topic, making it easy for you to find advanced simulation methodologies and application examples that are beyond the scope of the course curriculum.

Prerequisites

  • Basic understanding of optics and Maxwell's equations.

Target Audience

All photonics engineers.

Teaching Method

Video 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 FDTD.

Learning Path

Currently, no Learning Path available.

Learning Outcome

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

  • Understand how FDTD algorithm works in time domain and how it obtains frequency domain results.
  • Define and fine tune material properties.
  • Add and set up FDTD solver region.
  • Select suitable optical source and set it up for various simulation goals.
  • Add one or more monitors and record data of your interest.
  • Analyze and plot simulation results.

 Available Dates

Currently, no training dates available.

Learning Options

Training materials for this course are available with an Ansys Learning Hub Subscription. If there is no active public schedule available, private training can be arranged. 

Self-paced Learning 

Complete a class on your own schedule at your own pace. Scope is equivalent to Instructor led classes. Includes video lecture, workshops and input files. All our Self-Paced video courses are only available with an Ansys Learning Hub subscription.

 Agenda

The time commitment required for this self-paced course is about 10 hours (~ 2 hrs for each session). In addition to the video lectures and demos, various types of tests are provided throughout the course to validate the acquired knowledge. The following schedule is suggested for guidance, but you can take the course at your own pace.
