Description
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 insights and a degree of art. The techniques are not typically covered in a standard E&M curriculum. My motivation in developing this course is to share my experience in field calculations with first-time users. The goal is to build readers' knowledge and experience in steps so they can apply finite-element programs confidently. I emphasize hands-on operation rather than theoretical details. At the end of the course, students will be able to solve real-world problems with the following programs:
- EStat (2D electrostatics)
- HiPhi (3D electrostatics)
- PerMag (2D magnetostatics)
- Magnum (3D magnetostatics)
