Partition
Partition a domain with respect to a set of isolevels and add elements corresponding to the isosurfaces or contours.
Syntax
model.result().dataset().create(<dtag>,"Partition");
 
model.result().dataset(<dtag>).set(property,<value>);
 
model.result().dataset(<dtag>).createMesh(<compTag>,<geomTag>,<meshTag>,<importTag>);
model.result().dataset(<dtag>).createMeshPart(<compTag>,<geomTag>,<meshTag>,<importTag>);
Description
model.result().dataset().create(<dtag>,"Partition") creates a partition dataset with the name <dtag>.
The partition dataset makes it possible to partition a domain with respect to a set of isolevels and add elements corresponding to the isosurfaces or contours, using a scalar expression for which to apply the partitioning. Using the createMesh and createMeshPart methods, you can create a mesh or mesh part that refers to the Partition dataset.
The following properties are available:

Property
Value
Default
Description
data
none | dataset name
First compatible dataset
The solution dataset this feature refers to.
descr
String
 
A description for the expression to use for the partitioning.
expr
String
 
The expression for which to apply the partitioning.
isolevel
double array
Empty
The isolevels, if levelmethod is levels.
level
fromdataset | volume | surface | line | point
fromdataset
The geometry level to evaluate on.
levelmethod
number | levels
numbers
The definition of levels: a number of levels or a list of levels.
number
integer
1
The number of levels, if levelmethod is number.
numberrounding
true | false
true
Round the levels, if levelmethod is number.
propagatetolower
true | false
true
Propagate the filter to lower geometry dimensions.
smooth
none | material | internal | everywhere | expression
material
Smoothing settings. With material, smoothing is done inside domains with the same material. With internal, smoothing is done inside geometry domains. With expression, the smoothing is based on the expression in smoothexpr.
smoothexpr
String
dom
The expression to use for smoothing when smooth is set to expression.
threshold
manual | none
none
Use a smoothing threshold.
thresholdvalue
double
0.1
Threshold value (0-1), if threshold is set to manual.
unit
String
Model dependent
The unit to use for the expression in expr. If the old unit is not valid when the expression changes, the unit property is reset to default.
useder
true | false
true
Use cubic (Hermite) interpolation when applying the filter.
