From Model to Results

Every simulation follows the same seven steps.

  1. Model Import a STEP, DXF, GDS or Python file. Planar files get a layer stack-up.
  2. Materials Create materials and assign one to every solid.
  3. Ports Add wave ports on faces, sketch lumped ports, or draw layout ports.
  4. Settings Set the refinement frequency and mesh options, then add frequency sweeps and far-field sweeps.
  5. Validate and run Check the setup, run it, and follow the solver progress in the console.
  6. Results Plot fields, S-parameters and patterns, and export what you need.
  7. Iterate Copy a variant, change the design and compare results on the same axes.

State-of-the-Art Accuracy

WaveFEM is validated against Ansys HFSS on ten examples: five filters, three antennas and two transmission lines. Each is solved in both tools with the same geometry, the same adaptive refinement target (maximum ΔS of 0.02) and the same frequency sweep. The report compares S-parameter magnitude and phase, far-field realized gain, adaptive mesh convergence and runtime.

Waveguide Components

Simulate bandpass filters, adapters and multiplexers with precise S-parameter calculations for satellite and radar systems.

Documentation

First page of the WaveFEM manual WaveFEM User Manual (PDF)

The user manual takes you from importing a model to exporting results. It covers:

  • Installation and a tour of the interface
  • How the solver works
  • Importing STEP, DXF, GDS and Python models
  • Materials, ports and simulation settings
  • Running simulations, plotting and exporting results
  • Design variants
  • Worked examples: a horn antenna, a microstrip filter and a scripted waveguide bend
