dB/dt in flux 3D transient solver?

Hello Leon,

Thanks for writing.

It is possible to calculate the derivative of a curve within Flux, you can find more information here:

Hi Letizia,

Thanks for your reply.
I not only want to plot the 2D curve.

My goal is to calculate the time-domain ferrite core loss using the iGSE method. This requires integrating a function based on dB/dt, which is derived from the time-domain B(t) data.

Best regards,

Hello Leon,

Unfortunately is not possible within Flux: you should export the local quantities versus time and then use an external script to use the iGSE method and compute the derivative.

Alternatively, iron losses can be calculated using the "automatic" modified Bertotti method available in Flux.

Best regards,

Letizia
