Hello everybody i am trying to simulate some high air gap transformer. While Magnetostatic solution works fine , transient seems not to.

Actually i connect the first winding to a 90KHz voltage source and then in series with a capacitor.

The second winding in series with a Capacitor and a Resistance.

So while i expect currents around 25 A i get only 2.5 ... maybe maxwell doesn't work in high frequencies ? or could be something else wrong ? Anyone ? Thank you.

Hello there,

Thank you for bringing up this issue. There could be a few reasons why your transient simulation is not working as expected. First, it is possible that Maxwell does not work well with high frequencies. This could be due to the finite element method used in the simulation, which may not be accurate at high frequencies.

Another possibility is that there could be errors in your setup. For example, are you using the correct units for your voltage source and capacitors? Are the resistances and inductances of your windings accurately defined? These small errors can greatly affect the results of your simulation.

Another factor to consider is the material properties of your transformer. Are you using the correct properties for the core and windings? Different materials have different responses to high frequencies, so it is important to use the correct properties for accurate results.

Lastly, it could be an issue with convergence. Transient simulations can be more sensitive to convergence than static simulations. Make sure that your mesh is fine enough and that your simulation settings are appropriate for your model.

I hope these suggestions help you troubleshoot your simulation. If you continue to have issues, I suggest reaching out to the technical support team for further assistance. Good luck with your simulation!
