COMSOL 6.2 - MergeEntities

MergeEntities

Merge geometric entities of the mesh. The operation can merge points, edges, and boundaries within a tolerance.

Syntax

model.component(<ctag>).mesh(<tag>).create(<ftag>,"MergeEntities");

model.component(<ctag>).mesh(<tag>).feature(<ftag>).selection();

model.component(<ctag>).mesh(<tag>).feature(<ftag>).selection(property);

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

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

Description

Use model.component(<ctag>).mesh(<tag>).create(<ftag>,"MergeEntities") to merge entities in 3D mesh. Supported input: boundaries, edges, or points. Specify the entities to keep and the entities to be removed by the merge.

The following properties are available:

Table 4-27: Available Properties.
Property	Value	Default	Description
deformation	[0, 1]	0	Specifies how the deformation propagates in the mesh adjacent to the removed entities. 1 specifies a translation of the remove side.
dimension	0 \| 1 \| 2	2	Specifies the dimension of what to merge. 2 specifies boundaries.
distancetype	auto \| relative \| absolute	auto	Specifies the type maximum distance to enter.
keep	Selection		Specification of the entities to keep after the merge when pairing is manual.
maxabsdistance	double		Maximum absolute distance between entities to merge. Used when distancetype is maxabsdistance.
maxreldistance	double	0.01	Maximum relative distance between entities to merge. Used when distancetype is maxreldistance.
method	imprint \| one-to-one	imprint	Specifies how to pair the entities. The option imprint creates an imprint of the entities to remove on the keep side.
pairing	auto \| manual	auto	Specify how to pair the entities in the merge, automatically or manual specification of entities to keep and remove.
placement	linear \| curved	curved	Specifies the placement of mesh vertices on the entities to keep.
precision	[0, 1]	0.5	Specifies the precision with which to make the imprints. A value close to 1 gives a more exact imprint. Used when method is imprint.
remove	Selection		Specification of the entities to remove. Used when pairing is manual.
