Copy Face
For 3D models, use a Copy Face node () to make a copy of a mesh that you can use to create an identical mesh on, for example, two boundaries in a model with periodic boundary conditions.
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 in 3D 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 copy a mesh between faces:
•
In the Graphics window, select both the boundaries to copy the mesh from and the boundaries to copy the mesh to. On The Mesh Toolbar click the Copy Face () button. This adds a node with the same name and copies the mesh and includes the source boundaries set to the selected boundaries with a mesh and the destination boundaries set to the selected boundaries without a mesh.
-
In the Mesh ribbon toolbar (Windows), from the Operations>Copy () menu choose Copy Face.
-
In the Mesh contextual toolbar (macOS and Linux), from the Copy menu () choose Copy Face.
•
Right-click a Mesh node choose More Operations>Copy Face.
Then enter the properties for the copy meshing 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 many-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 destination (many-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, 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.

The Copy Edge feature has an orientation section. 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.
