Several analysis methods have been proposed for electromagnetic field analysis, and EMSolution uses the finite element method.
The question is, "Why the finite element method?" But this is too general a topic to discuss here. However, it is a very general question, so I will omit it. We believe that these are the reasons why the finite element method is often used.
-
- The finite element method is very versatile.
-
- Ease of formulation (derivatives are much easier than inte-grals)
-
- Handles sparse matrices and can withstand large-scale calculations with low computational speed and small capacity.
The following section describes specific methods.
