COMSOL 6.2 - CopyEdge

CopyEdge

Copy an edge mesh to copy meshes on edges.

Syntax

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

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>,"CopyEdge") to copy mesh between edges in a 2D or 3D geometry.

The following properties are available:

Table 4-20: Available Properties for CopyEdge.
Property	Value	Default	Description
copymethod	auto \| singlecopy \| arraycopy	auto	Type of copy operation.
direction	auto \| same \| opposite	auto	Direction of the copied mesh.
source	Selection	Empty	Source edges.
destination	Selection	Empty	Destination edges.
smoothcontrol	on \| off	on	Specifies if the operation smooths the mesh across removed control entities.
smoothmaxdepth	integer	4	Specifies the maximum element smoothing depth.
smoothmaxiter	integer	4	Specifies the number of smoothing iterations.

Use the properties source and destination to specify the source and destination edges. The copymethod property determines which type of copy is used: single copy (all-to-one), array copy (one-to-one), or automatic detection. The value auto lets the software choose between single copy (all-to-one), array copy (one-to-one), or a mixture of the two. The direction property controls the orientation of the copied mesh, and is relative the direction of the source edge with smallest number and the direction of the destination edge.

Copying a mesh is only possible if the destination edge is not adjacent to a meshed domain. The copy feature overwrites any existing mesh on the destination edge.

Example

Mesh Edge 1 and copy the mesh to Edges 2, 3, and 4.

Code for Use with Java

Model model = ModelUtil.create("Model");

model.component().create("comp1");

GeomSequence g = model.component("comp1").geom().create("geom1", 2);

MeshSequence m = model.component("comp1").mesh().create("mesh1", "geom1");

g.create("sq1", "Square");

g.run();

m.create("edg1", "Edge");

m.feature("edg1").selection().set(new int[]{1});
