My geometry nodes PEEC inductance solver can now take into account air gaps in a magnetic cores. This animations shows how having an air gap in a toroid will lower its permeability such that its effective permeability becomes dictated by the size of the air gap. #b3d #geometrynodes #science #engineering

@apilosov Yes that’s correct, it’s good enough to quickly experiment with designs, certainly not a replacement for any professional tool
I can model magnetics and calculate inductance of toroids! this a realtime PEEC solver running entirely inside geometry nodes, you can see the impact of changing turns, their spread across the toroid, how tight they are and changing the wire radius. Coming soon to ElectroMag Nodes #b3d #geometrynodes #electronics #science
Here are some high res renders of my simulation for induced eddy currents in conductive planes. A coil carrying high frequency AC when placed above a metal sheet will cause eddy currents to be induced in the sheet that cancel the magnetic field and reduce the coil’s inductance. Eddy current shielding is used in certain applications such as wireless power transfer and induction heating to create an asymmetric magnetic field that is strong on one side and weak on the other. #b3d
Now can simulate eddy currents with ElectroMag Node! This animation shows the a high frequency coil above a conductive plane, eddy currents are induced in the plane that cancel the magnetic field and reduce the coil’s inductance. Running entirely inside Blender with geometry nodes #b3d #science #engineering #geometrynodes
Fast self inductance and mutual inductance calculation based on geometry nodes, this solves the Neumann integral in realtime, allowing for any arbitrary coil geometry and orientation, coming soon as a free update to ElectroMag Nodes #b3d #geometrynodes #electronics #engineering #science
@Jay966591328971 yes I'm using Coilcraft 2929SQ air core inductors to compare, inductance result is close enough within 10% the resistance calculation begins to diverge and become unstable at frequencies above 1MHz.
continuing with my PEEC solver in Blender for inductors. Now I have a basic Python/Numba code that can calculate skin and proximity. You can see as the frequency increases the current shifts towards to the outer surface and also gets affected by adjacent turns #b3d #geometrynodes #electronics #Technology #science
working on creating a PEEC (partial element equivalent circuit) solver, instant calculation of inductance. Geometry nodes are becoming more and more powerful. This will be included in Electromag Nodes. #b3d #geometrynodes #electronics #technology #Science
@seekage_ solving Neumanns Integrals, also compared result with FastHenry
@KritischerP it will be able to calculate coupling between arbitrary coils, will be a free update to Electromag Nodes superhivemarket.com/products/elect…
@Jay966591328971 for now air core, but will be including magnetic materials
@Marc_Compere Yes, will be a free update toElectromag Nodes, superhivemarket.com/products/elect…
@deeperflows @TheAmpHour @Blender @eevblog Thanks!
I finally made on it on the @TheAmpHour podcast! Many thanks to Chris Gammell for having me on podcast, please check it out if you want to learn about all things @Blender and how I use it for modelling and visualisations in engineering. @eevblog #b3d #blender3d #engineering #science #3dart #3danimations
Power engineer and 3D graphic artist @samerps's #blender visualizations have helped many people understand how RF and magnetics acts in a variety of circuits. He talks about how to get started in Blender and the variety of tools available once you do. theamphour.com/695-making-the…
