Copy
For meshing sequences that are based upon a geometry, use a Copy node () to copy meshes within the same meshing sequence or between different meshing sequences (belonging to the same or different components). The dimension of the source meshing sequence must be less than or equal to the dimension of the destination meshing sequence. You can also copy a mesh from a mesh part.
The Copy feature can be useful if you start off with an imported mesh and then want to modify it by adding a boundary layer mesh or running a solver that modifies it, such as the adaptive solver. It also makes it possible to add geometry, such as for defining a surrounding domain, to an imported mesh while still keeping the imported mesh on the “original geometry”. Use the following steps to copy an imported mesh into another component’s geometry:
1
Import a mesh to an empty component or create a mesh part.
2
Add a new component in which you import the mesh as a geometry.
3
Add more geometry if desired.
4
In the new component’s meshing sequence, add a Copy feature that makes it possible to copy the imported mesh into this mesh.
5
Generate mesh on the additional geometry added in Step 3 or modify the mesh inserted in Step 4.
Enter the properties for the mesh copying operation using the following sections:
Source Mesh
From the Mesh list, select the meshing sequence or mesh part to copy from (or None, which is the default in 1D); then (for meshing sequences only) click Copy to copy the updated source mesh. By default, the meshing sequence in which the Copy node resides is selected. When this sequence is selected, the Copy button is unavailable. If you have parameterized the geometry or mesh and plan to run a parametric sweep, select the Build source mesh automatically check box to ensure that the source mesh and geometry are updated before copying. Otherwise, you have to manually rebuild the source mesh and click the Copy button if you want to use an updated source mesh. Click the Go to Source button () to move to the main Mesh node of the source mesh.
The sections below are available for 2D and 3D meshes only.
Dimension
Select the geometric entity level of the copy from the Geometric entity level list. The possible choices are Entire geometry, Domain (the default), Boundary, or Edge (3D only). For Entire geometry, the sections below are not available.
Source Entities
Use this section to select the entities to copy mesh from in the specified source mesh. From the Selection list, choose All domains (for example) or choose Manual to pick the entities from the Graphics window. Click the Active button to toggle between turning ON and OFF selections. Select the entities to copy the mesh from in the Graphics window. If you activate this selection, the Graphics window shows the mesh of the source sequence such that you can select entities in this mesh.
Click the Swap Source and Destination button () to swap the entities in the source list above and the entities in the destination list in the Destination Entities section below.
Destination Entities
This section is similar to the Source Entities section above, but you use it to define the geometric entities in the destination to which you want to copy the mesh.
Type of Copy
