Hi,
Do you have any simulation examples of how the core loss and winding loss for an inductor and a transformer could be obtained in simulation?
Depending on what you are looking for, this can be a very sophisticated question. The question should be: how to model core loss and winding loss for an inductor or transformer? There is a lot of research and application notes available on this topic.
Winding loss is generally the resistive loss in the wire used to wind the inductor/transformer. Core loss, on the other hand, is generally the magnetic loss in the core. Mathematically determining these two losses is very challenging, as both losses are frequency-dependent / nonlinear (skin effect in winding loss, hysteresis loss, or saturation loss in the core), and can depend on various parameters and physical constructions.
If you have no plans to delve into painful and complex mathematics and only want to add certain values to observe how they affect the waveform, the simple answer is:
- Winding Loss: Adding a series resistor to the inductor, e.g., 10mohms to a few hundred mohms.
- Core Loss: Adding a parallel resistor to the inductor, e.g., 1kohms to a few hundred kohms.
In practice, we can measure approximate values of these parameters with an impedance analyzer. However, you need a solid understanding of inductor/transformer modeling and how to properly use an LCR meter or impedance analyzer.
This forum may have other experts can help as they may deal with more practical situation in modeling loss.

I made a model of the JA core. A hysteresis loop is simulated.
Additionally, I added an increase in losses with increasing frequency. The loss power of magnetization reversal is considered to be the usual method - multiplying current by voltage. Similarly, the losses on the windings are considered. Here are some examples:
