Results

On the Results tab you read the results of the last run: tables of losses and component values, field views on the model, and graphs. Open in ParaView opens the full field results for your own analysis.

The shipped templates keep their tables and field views but not the full field files: run a template again before you open it in ParaView.

Results tab with the Summary of the Planar Winding template, with the losses at 100 kHz, the component values of the primary and secondary and the hotspot temperature
Summary (Planar Winding template): losses at 100 kHz, component values and the hotspot temperature.

In the picture: the list of views (1); the Losses (2), Component Values with its frequency box (3) and Temperature (4) boxes of the Summary.

Views

View (1) What it shows
Summary The losses, the component values, the hotspot temperature, the computation time, the log of the last successful run and the project size (details below).
Component Values Resistance, reactance, voltage and current of every winding, coil group and turn (Rdc, Rac Circuit, X, Urms, Irms, Ucomplex and more). The Value box picks the frequency.
Magnetic Flux, Coil Losses, Other Losses, Core Losses, Temperature The field on the model: flux density, loss densities and temperature, with a colour bar. The play button and the slider step through the frames the run produced, for example the time steps of a transient run.
Inductance Inductance runs only: see Inductance (frequency and excitation sweeps).
Graphs Any computed value (losses, field energies, currents) over frequency or time: tick Visible to add it to the plot.
Proximity Factors The Rac/Rdc factors of the Litz and stranded coil groups per frequency. In transient runs: with Dowell's Equation, the effective factor over a period, weighted by the harmonic amplitudes; with Rac/Rdc coefficient, the fixed Proximity Factor. Homogenized groups have no factor.
Capacitance Matrix With Capacitance on the Setup tab: the capacitance between all coil groups. The diagonal holds the capacitance of each group to the outer boundary.

Summary

Box What it holds
Losses (2) Primary, Secondary and Secondary2 Loss, Total Coil Loss, Core Loss, Other Loss and Total Loss [W]. Harmonic runs show one column per frequency and their Sum; transient runs show the losses averaged over full periods.
Component Values (3) R DC coil, R AC source, Urms, Irms, Complex Power, Iph and Uph of the primary and the secondary, for the frequency chosen in the box.
Temperature (4) Hotspot [°C]: the highest temperature in the model, with steady-state heat transfer.
Interwinding Capacitance With Capacitance: between primary and secondary, summed from the capacitance matrix.
Computation Time Mesh generation, simulation and postprocessing time, then the log file of the last successful run and the project size.
Temperature view of the Planar Winding template with the core and the windings coloured from 50 to 60.5 degrees Celsius
Temperature view of the same run: the windings inside the core are the hottest parts, up to 60.5 °C.

Inductance, Rac and Q

How the inductance, resistance and Q values on the Results tab are computed, per frequency. V and I are the complex voltage and current of the winding's source, ω = 2πf.

Quantity Definition What it includes
Circuit Inductance Im(V/I)/ω The inductance the circuit sees at the terminals.
Energy Inductance 2W/I², W the magnetic energy of the whole model The energy of all currents together: with several windings carrying current, it is not the inductance of one winding.
Rac Circuit; R AC source in the Summary Re(V/I) Every loss inside the field solution: winding loss, eddy-current loss in cores and other parts, and the core loss of a complex-permeability core. Not the core loss that the core-loss model (Steinmetz, GSE, iGSE) computes after the solve. With a loaded secondary, it also holds the power passed to it.
Rac Loss Winding loss / Irms² The winding only: DC, skin and proximity loss.
Q Factor X / Rac Circuit, X = Im(V/I) The losses in Rac Circuit.

Q from the losses, 2πf·L divided by (coil loss + core loss)/Irms², also counts the core loss computed after the solve and can differ a lot from Q Factor: in the Planar Inductor template it is 162 at 5 kHz, against a Q Factor of 223. Sweeps over frequency or excitation: Inductance (frequency and excitation sweeps).
