Copy Face
Use Copy Face () to make a copy a boundary mesh using a rigid body transformation with a scale factor.
Figure 8-38: Copy the source mesh (yellow) to the destination faces (magenta) with Copy Face. Some boundaries are hidden for visibility.
This operation is supported in 3D models only.
To ensure identical meshes on periodic and symmetric boundaries, consider using the Identical Mesh attribute instead of a copy operation.
Copying a mesh to a face that is adjacent to a meshed face is possible if the edges between these faces have the same number of elements as the corresponding source edges. The mesh on the destination edges is kept and the copied face elements are modified to fit with this edge mesh.
The edges around the source and destination faces are allowed to be partitioned differently, but only in such a way that several edges of the source face map to one edge of the destination edge, not the other way around.
Copying a face mesh is only possible if the destination face is not adjacent to any meshed domain. The copy node overwrites any existing mesh on the destination face.
To add a Copy Faces node, select one or several meshed source boundaries and unmeshed destination boundaries, then choose one of the following:
•
In The Mesh Toolbar, choose Copy Faces from the Copy () menu.
•
Right-click the Mesh node and choose Copy Faces from the Copying Operations menu.
Then enter the properties for the copy operation using the following sections:
Source and Destination Boundaries
It is possible to copy a mesh from one or several source boundaries onto one or several destination boundaries. The source (or their combination, if Single copy (all-to-one) is used) must be a connected set 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 Active button to toggle between turning ON and OFF selections. Select the boundaries to copy the mesh from in the Graphics window.
The source boundaries must be connected when the Single copy (all-to-one) option is specified as the Type of Copy. 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 Face nodes.
Swap Source and Destination
Click the Swap Source and Destination 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 Copy operation.
Control Entities
Select the Smooth across removed control entities check box to smooth the transition in element size across removed control entities. You can specify the number of smoothing iterations in the Number of iterations field. In the Maximum element depth to process 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 Face node, right-click and add an Edge Map, One-Point Map, or Two-Point Map node as a local attribute.
