COMSOL 6.2 - CrossSection

CrossSection

Create a 2D geometry from a cross section of a 3D geometry.

Syntax

model.component(<ctag>).geom(<tag>).create(<ftag>,"CrossSection");

model.component(<ctag>).geom(<tag>).feature(<ftag>).selection("input");

model.component(<ctag>).geom(<tag>).feature(<ftag>).set(property,<value>);

model.component(<ctag>).geom(<tag>).feature(<ftag>).getType(property);

model.component(<ctag>).geom(<tag>).feature(<ftag>).setAttribute(attribute,<value>);

model.component(<ctag>).geom(<tag>).feature(<ftag>).getAttribute(attribute);

Description

In a 2D geometry, use model.component(<ctag>).geom(<tag>).create(<ftag>,"CrossSection") to create 2D geometry objects by intersecting 3D geometry objects with a work plane. Select the work plane using the workplane property, whose value is the 3D sequence’s tag followed by a slash and the work plane feature’s tag, for example geom1/wp1. By default, you get the last work plane in the last 3D geometry.

In a 2D sequence of a work plane feature, use model.component(<ctag>).geom(<tag>).feature(<wptag>).geom().create(<ftag>,"CrossSection") to create 2D geometry objects by intersecting 3D geometry objects with the work plane.

By default, you get the intersection for all 3D objects that were generated by the features preceding the work plane feature. To select a subset of these objects, set the intersect property to selected, and use the property input to select the 3D objects to intersect.

The following properties are available:

Table 3-56: Valid Property/Value Pairs.
Property	Value	Default	Description
absrepairtol	double	...geom(<tag>).absRepairTol()	Absolute repair tolerance.
color	none \| custom \| integer between 1 and the number of colors in the current theme	none	The color of the selection, either given as an integer indicating a color in the color theme, or as a custom color in the customcolor property. Coloring is only available when selresult in active.
contributeto	String	none	Tag of cumulative selection to contribute to.
customcolor	RGB-triplet	Next available theme color	The color to use. Active when color is set to custom.
input	Selection	empty	Selection of objects to intersect.
intersect	all \| selected	all	Intersect all objects or selected objects.
repairtol	double	...geom(<tag>). repairTol()	Relative repair tolerance, relative to size of each input object.
repairtoltype	auto \| relative \| absolute	...geom(<tag>). repairTolType()	Repair tolerance type: automatic, relative, or absolute.
selfrom3D	true \| false	false	Create selections from the 3D geometry.
selfrom3dshow	true \| false	false	Show created selections from 3D in, for example, material and physics settings. Not available for in work planes.
selresult	on \| off	off	Create selections of all resulting objects.
selresultshow	all \| obj \| dom \| bnd \| pnt \| off	dom	Show selections, if selresult is on, in physics, materials, and so on; in part instances; or in 3D from a plane geometry. obj is not available in a component’s geometry. dom, bnd, and edg are not available in all features.
workplane	String		Work plane to intersect with.

The following attributes are available:

Table 3-57: Valid attributes
Name	Value	Default	Description
construction	on \| off \| inherit	inherit	Designate the resulting objects as construction geometry. Use inherit to set the construction geometry attribute only if all input objects are construction geometry.
