Use a Partition dataset (
), select from the
More Datasets submenu, to partition a domain with respect to a set of isolevels and add elements corresponding to the isosurfaces or contours. It is also possible to use a Partition dataset as the source for a mesh import (see
Importing Meshes). It is then the result of the evaluation of the Partition dataset that is used. If needed, right-click to add a
Mesh Import Parameters subnode.
Right-click the Partition node or click the
Attributes menu in the
Results toolbar to choose
Create Mesh in New Component or
Create Mesh Part. In both cases, an
Import node is added to import the geometry that is the result of the partitioning as a mesh from the dataset, in a new model component or as a mesh part, respectively.
From the Entry method list, choose
Number of levels (the default) and then enter the total number of levels in the
Total levels field (default: 1) and clear or select the
Round the levels check box (selected by default) if desired. Alternatively, choose
Levels and then enter the desired isolevels in the
Levels field.
By default, the Geometry level list is set to
From dataset. If desired, choose
Volume,
Surface,
Line, or
Point instead. The
Propagate to lower dimensions check box is selected by default; clear it if you do not want the partitioning to propagate.
Select a data Smoothing method —
None,
Inside material domains (the default, for smoothing within domains shared by the same material but not across material boundaries),
Inside geometry domains (for smoothing within each geometry domain but not across interior boundaries),
Everywhere, or
Expression. If you choose
Expression, enter an expression in the
Expression field such that smoothing occurs where the expression is continuous. The default expression is
dom, the domain variable, which is equivalent to the
Internal smoothing. You can also — in a surface plot, for example — use
material.domain, which is an indicator variable for domains that share the same material (see
Material Group Indicator Variables) and is equivalent to the
Inside material domains setting. For all
Smoothing methods except
None, you can also choose smoothing threshold, if needed. From the
Smoothing threshold list, select
None (the default), or select
Manual to enter a relative smoothing threshold value (default: 0.1) in the
Threshold field. The
Use derivatives check box controls whether cubic (Hermite) interpolation is used when applying the filter and is selected by default. It can give a better-looking plot for most expressions.
Under Advanced, define the name of the
Part variable: By default, it is
part1part. It evaluates to 0, 1, and so on for the parts that the geometry is split into. For example, you can create a surface plot of
part1part to visualize that numbering.
