Selecting Solution Quantities to Plot
Each trace in a report includes a quantity that is plotted along an axis. The quantity being plotted can be a value that was calculated by Maxwell, such as L11, or a value from a calculated expression.
To select a parameter to plot:
- In the Report dialog box, select
one of the solution type dependent categories. Some of the available
categories and descriptions of their associated quantities are listed below. The actual list you see will depend upon
the solution type and solution setup for your design.
The selected category provides the default name for the plot, such as Force Plot n. You can edit the plot names in the project tree and the plot header in the report properties.
Variables
Intrinsic variables, such as frequency or theta, or user-defined project variables, such as the length of a quarter-wave transformer.
Output Variables
Derived quantities from the original field solution.
L, R, or Z
Inductance, Resistance, and Impedance matrix entries when the matrix parameter is defined.
Force or Torque
Force or Torque values when the parameter is defined.
Loss
Loss quantities for 2D and 3D transient solutions include: CoreLoss, EddyCurrentLoss, ExcessLoss, HysteresisLoss, SolidLoss, StrandedLoss, StrandedLossR, and StrandedLossAC. 1
The availability of solution data for CoreLoss, EddyCurrentLoss, ExcessLoss, and HysteresisLoss depends on the material definitions in the design:
- If the design is hysteresis model-based, the solver provides solution data to plot only for HysteresisLoss, EddyCurrentLoss, and TotalLoss.
- If the design contains a non- hysteresis based model, core loss model type: Electrical Steel, the solver provides solution data to plot for all four quantities (CoreLoss, EddyCurrentLoss, ExcessLoss, and HysteresisLoss ).
- For all other cases (for example: linear, power ferrite), the solver provides solution data to plot only for CoreLoss.
Note: For 2D transient solutions only, object-based quantities of CoreLoss, EddyCurrentLoss, ExcessLoss, and HysteresisLoss are also calculated, and can be selected for plotting, for objects whose Core Loss Setting has been checked in the Set Core Loss dialog box.- Loss quantities for 2D and 3D eddy current solutions include: CoreLoss, SolidLoss, StrandedLoss, StrandedLossAC, and StrandedLossR.
End Connection - If a 2D transient End Connection excitation has been assigned, quantities include: Current, InducedVoltage, RingCurrent (the current in the first segment of the ring), and SolidLoss.
- If a 2D eddy current End Connection excitation has been assigned, quantities include: Current and InducedVoltage.
Expression Cache The values of expressions listed in the Expression cache of the Solution setup can be plotted, for example, as a function of adaptive pass to monitor their convergence. Expression Converge
This can be used to plot convergence, as a function of adaptive pass, of expressions defined in the Expression cache of the Solution setup. When defining the report, for "Context", select Solution: SetupN:Adaptive Pass. 1NOTE: StrandedLoss includes DC losses only; while StrandedLossAC includes DC losses and additional AC losses due to skin effect and proximity effect.
- Select a quantity to plot from the Quantity list. The available quantities depend on the selected category and the setup of the design.
