Powerful features (2)
ACIS-Based Modeler, “Undo”, Macros Materials include lumped RLC elements and ferrites Perfectly-Matched Layer (PML) Periodic Boundaries or Linked Boundaries Optimetrics Module: Parametrics and Optimization 3D Eigenmode Solver

Limitations
- Frequency domain, not time domain
Exception: some post processing on S11 after wide frequency sweep

- Linear materials
Exception: ferrite applications with M3DFS involved

- Passive structures
Exception: special application of mas
