Copy Domain

The operation creates identical meshes on domains. The (2D(

) or 3D(

)) operation will automatically select a suitable copy type, or manually select to either copy a set of meshed domains onto each destination domain separately, or to copy each meshed domain onto a single unmeshed domain (as shown in Figure 8-33).

Figure 8-33: Copy the source mesh (yellow) to the destination domains (magenta) with a Copy Domain operation. The image to the right shows the resulting mesh after building the operation.

Copying a mesh to a destination domain in 2D that is adjacent to a meshed domain is possible if the edges between these domains have the same number of elements as the corresponding source edges. The mesh on the destination edges is kept and the copied domain elements are modified to fit with this edge mesh.

Copying a mesh to a destination domain in 3D that is adjacent to a meshed domain is also possible if each face between these domains has a mesh isomorphic to a mesh of the corresponding source face. The mesh on the destination face is kept and the copied domain elements are modified to fit with this face mesh.

The edges around the source and destination domains in 2D are allowed to be partitioned differently but only in such a way that several edges of the source domain map to one edge of the destination edge. Not the other way around.

The faces around the source and destination domains in 3D are also allowed to be partitioned differently with exactly that same limitation as for edges in 2D (source to destination face mapping must be many-to-one).

If you copy between domains with a common boundary, the copy operation mirrors the mesh if the domains are symmetric (see the upper right image in Figure 8-37). If the domains are symmetric but separated from each other, you can enforce a mirrored mesh by adding an Edge Map or a Transform attribute that controls the orientation of the copied mesh.

To copy a mesh between domains, select one or several meshed source domains and unmeshed destination domains, then:

•

Right-click in the window, and select from the menu. For more information, see The Graphics Context Menu.

•

In The Mesh Toolbar, choose from the (

) menu.

•

Right-click the node and choose from the menu.

Then enter the properties for the copy operation using the following sections:

Source and Destination Domains

It is possible to copy a mesh from one or several source domains onto one or several destination domains. The source must be of exactly the same shape as the corresponding destination, up to a constant scaling factor. More precisely, the distance between any two geometry vertices on the destination is required to be the same, up to a constant scaling factor, as the distance between the corresponding geometry vertices on the source.

Click the button to toggle between turning ON

and OFF

selections. Select the domains to copy the mesh from in the window.


	The source domains must be connected when the Single copy (all-to-one) option is specified. In an assembly, an identity pair is not sufficient to connect boundaries across parts. Instead, use the Automatic option or consider forming a union of the parts or splitting the destination boundary (using imprints, for example) so that the mesh copy is a one-to-one copy operation using two or more Copy Domain nodes.

Swap Source and Destination

Click the button (

) to switch source and destination selections. Edge map is available to be switched, if provided.

Type of Copy

For settings information, see Type of Copy for the operation.

Control Entities

Select the check box to smooth the transition in element size across removed control entities. You can specify the number of smoothing iterations in the field. In the field you can specify the maximum element depth, from the removed control entity.


	To control the orientation of the source mesh on the destination when using the Copy Domain node, right-click and add an Edge Map, One-Point Map, or Transform node as a local attribute.
