KiCAD PCB Layout Simulation With OpenEMS (FDTD)
The holy grail of EM simulation would be an open source CAD and solver.
Firstly, don’t expect this to hold a candle existing, well developed, computational software in the marker. This is a hastily developed tool I made on my laptop. It currently only supports lumped ports and doesn’t allow full manipulation of the model and boundary conditions. I am also working on how to integrate thick metals, although for the current PCBs I am simulating this a non issue.
Simulated results are pending measured verification. Simulated verification may be problematic in the legal aspect.

- Model simplification, meshing, lumped ports and running the first simulations. Read more…
- Demonstrating improvements to the interface and also some well known trouble with transient methods. Read more…
