COMSOL 6.2 - Copy

Copy

Copy a mesh between edges, boundaries, domains, or between different meshing sequences. In 2D and 3D, use the attributes EdgeMap, OnePointMap, TwoPointMap to control the orientation of the source mesh on the destination.

Syntax

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

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

model.component(<ctag>).mesh(<tag>).feature(<ftag>).create(<ftag1>,maptype);

Description

Use model.component(<ctag>).mesh(<tag>).create(<ftag>,"Copy") to copy a mesh between meshing sequences. Any meshing sequence can be used as the source of the operation, whereas the destination sequence cannot contain an imported mesh. The dimension of the source sequence must be less than or equal to the dimension of the destination sequence.

The following properties are available (for 1D meshes, only the mesh property is available):

Table 4-23: Available Properties for Copy.
Property	Value	Default	Description
mesh	String \| none	Native sequence (none in 1D)	Specifies the source mesh.
copymethod	auto \| singlecopy \| arraycopy	auto	Type of copy operation.
dimension	all, 1, 2, or 3 (in 3D)	2 in 2D, 3 in 3D	Specifies the dimension for the operation. all means that the entire mesh should be copied.
source	Selection	Empty	Specifies the selection of source entities.
buildsource	on \| off	off	Build source mesh automatically.
destination	Selection	Empty	Specifies the selection of destination entities.
smoothcontrol	on \| off	on	Specifies if the operation smooths the mesh across removed control entities.
smoothmaxiter	integer	4	Specifies the number of smoothing iterations.
smoothmaxdepth	integer	4	Specifies the maximum element smoothing depth.

Use the properties source and destination to specify the geometric entities of the source and destination (except when the dimension is set to copy the entire geometry). 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.

Example

The following example shows how to use the Copy feature with a modified geometry from an imported mesh:

Code for Use with Java

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

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

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

geom1.create("c1", "Circle");

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

mesh1.run();

model.component().create("comp2");

GeomSequence geom2 = model.component("comp2").geom().create("geom2", 2);

GeomFeature imp1 = geom2.create("imp1", "Import");
