About Datasets
Datasets refer to the source of data for creating Plots and Reports. It can be a Solution, a Mesh, or some transformation or cut plane applied to other datasets — that is, you can create new datasets from other datasets. You add datasets to the Datasets branch () under Results.
All plots refer to datasets; the solutions are always available as default datasets. Characteristics of a dataset include:
•
A visualization mesh
•
Mapping to a previous dataset (except for solutions and meshes)
•
Ability to refer the evaluation to the previous dataset
The base dataset maps to a solution and geometry or some other source of data. An example of a transformation dataset is Revolution 2D, which sweeps a 2D dataset into 3D.
Cut Point, Cut Line, Cut Plane, Edge 2D, Edge 3D, and Surface datasets are used in combination with plot groups and Line, Point, and Surface graphs to create cross-sectional plots and plots for data in points, along lines and edges, and on cut planes and surfaces.
Integration over solution datasets (or using the Integration coupling operator) uses the most accurate integration method (Gaussian quadrature) whereas most other datasets use less accurate integration methods (typically the trapezoid method) because they do not operate on original elements of the finite element mesh.
Datasets such as Mirror mirror vectors (used in, for example, arrow plots, streamline plots, and deformations) but not scalars.
Adding a Dataset to the Model Builder
In the Model Builder under Results (), right-click Datasets () and select an option from the context menu. Continue defining each dataset as described. See Table 21-7 for links to all the types of datasets.

Depending on the physics interface included in the model, not all dataset types in the following table may be available. To see all dataset types, select the All Dataset Types check box in the Show More Options dialog box.
Exporting Data from Datasets
For most datasets, you can right-click the dataset node and choose Add Data to Export. A Data node is then added under Results>Export, where you can define the content and format for the data output and export it to a file.
For datasets that also include a mesh, such as Solution and Mesh datasets, you can also right-click the dataset and choose Add Mesh to Export. A Mesh (Export) node is then added under Results>Export, where you can define the content and format for the mesh data output and export it to a file.
