3D Coil Modeling

Course Overview

This course is an introduction to modeling electromagnetic coils in the 3D. Here, you will learn about some unique issues that you will need to address when working in the 3D space. An overview of the course materials and topics covered are listed below:

• Part 1: Introduction to Modeling Electromagnetic Coils in 3D
  • Building a 3D coil model from scratch, using both the Magnetic Fields and Magnetic and Electric Fields interfaces
• Part 2: Exciting 3D Electromagnetic Coil Structures
  • Special features for modeling of multiturn coils, thin pancake coils, and tightly-packed coils
  • Estimating coil capacitance
  • Correct interpretation of boundary conditions as current return paths, electric insulators, or symmetry conditions
• Part 3: Using Infinite Elements to Terminate Domains for 3D Coil Models
  • Using Infinite Elements for modeling domain truncation
  • Built-in coil modeling options
  • Using edges to excite coils or compute intercepted flux
• Part 4: Frequency-Domain Modeling of Electromagnetic Coils in 3D
  • Delineating the three modeling regimes, the low-, mid-, and high-frequency regimes, and how to address them via the Magnetic Fields and Magnetic and Electric Fields interfaces
  • Issues of meshing and solver convergence
• Part 5: Modeling Resonance and Coupling Between Electromagnetic Coils
  • Modeling resonant frequency of the coil
  • Computing the coupling between coils in 3D
  • Summary of the various modeling approaches

Upon completing this course, you will know the foundations of how to set up, build, and compute 3D models of electromganetic coils. You will also be knowledgeable in the key aspects of building such models.
