Get Started

The "My First Simulation" course of the CHARGE Learning Track includes a steady-state simulation performed by the CHARGE solver. This course introduces basic examples of other simulation modes that the CHARGE solver is capable of, including the small-signal AC and transient (time-dependent) simulation modes. It also contains a hands-on demo of small-signal AC and transient simulations of a simple p-i-n diode.

In this course, we will demonstrate the application of the Ansys Lumerical CHARGE solver for steady-state analysis of a simple p-n junction diode. This is a basic example of how the CHARGE solver can be used for electrical analysis of a simple system. We will walk you through the workflow of the simulation including how to set up, run, and analyze the results of the simulation. You will also get familiar with the main parts of the Finite Element IDE user interface.

This course contains useful information about various material models used by the Ansys Lumerical CHARGE solver for electrical simulation. You will also get to know the material database which contains the electrical properties of commonly used materials.

In this course, various simulation objects available in the CHARGE solver such as doping profiles, sources, monitors, and boundary conditions are introduced and the different settings required to set up these objects are briefly reviewed. Also, a number of tips for efficient geometry setup in the Finite Element IDE design environment are provided.
