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

Course Overview

This course introduces the Lumerical Discontinuous-Galerkin Time-Domain (DGTD) solver for optical simulations, one of the four solvers in the finite-element IDE. It is primarily intended for beginner to intermediate users, with a focus on providing practical examples to common tasks. You will learn the basic solver physics and how to use various simulation objects in a typical workflow - simulation setup, running simulations, and post-processing and visualizing results.

Prerequisites

  • Basic understanding of electromagnetics theory. 

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 FDE.

Learning Path

Currently, no Learning Path available.

Learning Outcome

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

  • Understand the basics of DGTD algorithm.
  • Recognize the main differences between FDTD and DGTD.
  • Familiarize yourself with how geometries are built in the finite-element IDE.
  • Understand the typical workflow - set up the simulation, run simulations, and analyze the results.
  • Run standard convergence tests and understand why it is necessary.

 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 2 hours. 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.
