MagNet uses the finite element technique for an accurate and quick solution of Maxwell's equations. Each module is tailored to simulate different types of electromagnetic fields and is available separately for both 2D & 3D designs.

Transient or Time-varying electromagnetic fields

• Non-linear analysis
• Second-order time stepping
• Resume Feature: pause at a particular time step for inspection
• Core losses, proximity effects and eddy currents
• Motion
  • Supports rotational, linear and general (multiple degrees of freedom) motion
  • Velocity & load driven motion problems
  • Computes induced currents due to motion
  • Supports multiple moving components

AC or Time Harmonic electromagnetic fields

• Analysis based on a single frequency in the complex domain
