SUMMARY

The discussion centers on the use of the Finite Element Method Magnetics (FEMM) software for simulating a magnetostatic problem without explicitly providing the Laplace equation, represented as ##\dfrac{\partial^2 V}{\partial x^2} + \dfrac{\partial^2 V}{\partial y^2} = 0##. The tutorial indicates that specifying the physics is essential, but the absence of the Laplace equation does not hinder the simulation's accuracy. Users are encouraged to follow the tutorial closely, particularly the sections at 3:26 and 10:51, to understand the setup process.

PREREQUISITES
  • Familiarity with Finite Element Method Magnetics (FEMM) software
  • Understanding of partial differential equations (PDEs)
  • Basic knowledge of magnetostatic problems
  • Ability to follow video tutorials effectively
NEXT STEPS
  • Review the FEMM user manual for detailed instructions on setting up simulations
  • Study the tutorial video series, focusing on the sections that discuss specifying physics in FEMM
  • Learn about the implications of omitting boundary conditions in FEMM simulations
  • Explore additional resources on solving PDEs in magnetostatic contexts
USEFUL FOR

This discussion is beneficial for engineers, physicists, and students involved in computational electromagnetics, particularly those using FEMM for magnetostatic simulations.

I'm following this tutorial
I noticed that he provided the boundary values in FEMM but he didn't provide the Laplace equation ##\dfrac{\partial^2 V}{\partial x^2} + \dfrac{\partial^2 V}{\partial y^2} = 0## for the field but it is still corrected simulated?
or is it not necessary to provide it at all?

See at 10:51ff: "The next step is to specify the physics [ie. tell it what PDE to solve]. That actually was our first step, when we created the design, we created the magnetostatic problem [at 3:26 in the first video of the series]."
