Solve problems that model electric and magnetic fields

Solve PDEs that model static electric and magnetic fields. A typical programmatic workflow for solving an electromagnetic problem includes the following steps:

  • Create a special electromagnetic model container for an electrostatic, magnetostatic, or harmonic analysis.

  • Define a geometry and mesh it.

  • 分配材料的电磁特性，例如相对介电常数，相对渗透率和电导率。

  • Specify charge or current density within the geometry.

  • 在边界上指定电压，磁电势，电气或磁场。

  • Specify absorbing boundary conditions.

  • Solve and plot results, such as the resulting electric or magnetic potentials, fields, and flux densities.
