Selecting a Dataset for Plots and Postprocessing
Almost every plot type’s Settings window includes a Data section where you select a Dataset from a list of available and applicable datasets. From parent (the default) means that the plot uses the same dataset as the plot group to which it belongs. Click the Go to Source button () to move to the dataset node to which the selection in the list next to the button refers.
Under Data, select a Dataset. Select:
•
From parent (the default) to use the same dataset as the plot group to which it belongs.
•
A Data/Solution or Data/Parametric Solution dataset to visualize a quantity from that solution.
•
Other applicable types of datasets for the plot. For a 1D plot, for example, you can use a Cut Line dataset to visualize a quantity along the cut line (a cross section) or a Parametric Curve dataset to visualize a quantity along the parametric curve.
•
None to not use any of the available datasets.
For plots where the selected dataset has the same nontrivial parameter structure as the dataset used in the parent plot group (typically, a solution that contains solution data for more than one time, eigenmode, or parameter), you can choose from where to take the solution parameters. From the Solution parameters list, choose Manual to choose a time, eigenmode, or parameter using the settings described below, or choose From parent to use those values from the corresponding settings in the parent plot group. Using the settings from the plot group can make it easier to work with plot groups where multiple datasets are used.
In addition, other lists can appear underneath the Dataset list for parametric, time-dependent, eigenmode, and adaptive mesh refinement solutions, as well as for evaluation of derived values:
•
For parametric solutions, choose a parameter from the Parameter value list or, if applicable, from the Parameter selection list or separate lists from a parameter switch (see Inputs for Parametric Solver and Parametric Sweep Studies below). For a material sweep or function sweep, use the Switch list to choose a material or function for which to plot the corresponding solution.
•
For time-dependent solutions, choose the time of the solution to use from the Time list for 2D and 3D plots. In addition you choose Interpolated for specifying an interpolated time in the text field that appears. You can also choose Last for the last solution in the list of times. It can be useful, for example, in models where the number of time steps depends on a parameter in a parametric sweep. For 1D plots and data evaluation, choose from the Time selection list: All to use all time steps, First, Last, From list to select from a list of all time steps, Manual to enter a range of times as indices directly, or Interpolated to enter Times.
•
For eigenmode solutions, choose the eigenmode or eigenvalue of the solution to use from the Eigenmode or Eigenvalue list. For 1D plots and data evaluation, choose from the Eigenmode selection or Eigenvalue selection list: All to use all eigenmodes, First, Last, From list to select from a list of all eigenmodes, or Manual to enter a range of eigenmodes as indices directly.
•
For solutions using adaptive mesh refinement (selecting a Solution dataset for the adaptive mesh refinement solutions), choose a refinement level from the Parameter selection (Refinement level) list. Level 0 is the base level (no mesh adaptation), and the highest level represents the final adaptive mesh refinement solution. For 1D plots and data evaluation, choose from the Parameter selection (Refinement level) list: All to use all refinement levels; First, Last, or From list to select from a list of all refinement levels; or Manual to enter a range of refinement levels as indices directly.
Datasets
In Parameter value and Time lists with more than 100 parameter values or time steps, the values are grouped in sets of 100 for a better overview. Expand the section for the value that you want to plot a solution for.
