Field Precision releases free electronic course on 3D electric and magnetic field calculations

Field Precision has expanded its library of free educational materials with the electronic course "Electric and Magnetic Field Calculations with Finite-element Methods," a step-by-step tutorial for scientists and engineers.
 
ALBUQUERQUE, N.M. - Jan. 5, 2015 - PRLog -- The power of modern personal computers makes fully three-dimensional finite-element calculations of electric and magnetic fields a practical reality for any scientist or engineer. Rough estimates can be replaced with numerically-exact values for complex geometries and material responses. Hours of tedious benchmarking can be circumvented. Despite the benefits, many researchers hesitate to get involved because of the learning curve. Effective numerical simulations involve a degree of art usually not taught in the standard electromagnetism curriculum. The goal of Field Precision in developing the course "Electric and magnetic field calculations with finite-element methods" is to share simulation experience in field calculations with first-time users. The strategy is to build students' knowledge and experience in steps so they can apply finite-element programs confidently. The course emphasizes hands-on operation rather than theoretical details. Included is a 124-page textbook and an archive of input files for the examples discussed. The text was prepared by Dr. Stanley Humphries, Professor Emeritus of Electrical and Computer Engineering at the University of New Mexico and author of the texts Principles of Charged Particle Acceleration (Wiley, 1986), Charged Particle Beams (Wiley, 1990) and Field Solutions on Computer.

The course concentrates on static electric and magnetic fields, covering a wide of applications. Examples include high-voltage systems, power transmission, electrostatic separators, MRI magnets, motors, shielding and permanent-magnet assemblies. The target audience is researchers and graduate students with a basic knowledge of electromagnetism but with no required experience in numerical methods. Materials hare presented in a graduated sequence to build knowledge, from easy 2D calculations to advanced 3D simulations. All steps are illustrated with examples. The course includes the following sections:

Section 1. Introduction
Section 2. Installing 2D electric-field software
Section 3. First 2D electrostatic solution
Section 4. Electrostatic application: building the mesh
Section 5. Electrostatic application: calculating and analyzing fields
Section 6. Electrostatic application: meshing and accuracy
Section 7. Magnetostatic solution: simple coil with boundaries
Section 8. Magnetostatic solution: boundary effects and automatic operation
Section 9. Magnetostatic solution: the role of steel
Section 10. Magnetostatic solution: when steel gets complicated
Section 11. Magnetostatic solution: permanent magnets
Section 12. Adding 3D software
Section 13. 3D electrostatic example: STL input
Section 14. 3D electrostatic example: mesh generation and solution
Section 15. 3D electrostatic application: getting started
Section 16. 3D electrostatic application: extrusions
Section 17. 3D electrostatic application: mutual capacitance
Section 18. 3D magnetic fields: defining coil currents
Section 19. 3D magnetic fields: free-space calculations
Section 20. 3D magnetic fields: iron and permanent magnets
