How to Use HarnessFlow
We have several wire harness examples ready to try:
- Click Examples to browse available harness configurations.
- Choose a harness. Option 4 (Shielded Twisted Pair) is a good starting point.
- Click Run to simulate – computes the capacitance and inductance matrices.
- Click Export to generate and download an S-parameter model compatible with HyperLynx, ADS, or the S-Param to PSpice tool.
What Does HarnessFlow Calculate?
- Capacitance and inductance matrices (Method of Moments)
- Dielectric conductance losses
- Radiation resistance and series wire resistance
- Skin effect and shield transfer impedance
- Full S-parameter model over a specified frequency range and harness length
Accuracy
Verification testing shows capacitance within 1% of analytical equations. Inductance is derived from the MTL capacitance matrix using a TEM-mode assumption. Other parameters use analytical approximations for fast, reliable results.
About HarnessFlow
HarnessFlow is free to use and built on the open-source PyCoupling project (started 2021). Questions or validation requests: russell@emisleuth.com
