| # This example demonstrates how to set up and solve a busbar Joule heating analysis using PyAEDT. | ||
| # The analysis captures frequency-dependent phenomena including skin effect, current redistribution, | ||
| # and AC losses in power electronics systems. |

Not only in electronic systems, but all bus bar applications.

Sure I will update it

How about adding a comment explaining that the faces' IDs can be retrieved from the UI and entered here as well?

Why not a skin depth mesh operation?
|
|
||
| # Loss density | ||
| loss_density = (total_loss / busbar_volume) if busbar_volume else 0.0 | ||
| print(f"Loss density: {loss_density:.8f} W/mm³") |

Is the volume returning mm3? or m3?

Why here?
Add the Skin depth calculation before the mesh operation.

This comparison may not be accurate. How about cases when the bar dimension is marginally bigger or smaller than 2 * skin_depth_mm?
You can also move it to the beginning and create a section for the skin depth analysis.
