Creating Geometry from Mesh
A mesh imported into COMSOL Multiphysics can be used to construct a geometry.
Figure 8-26: A geometry is created from the imported STL mesh of a vertebra. The geometry of the vertebra is combined with the geometry of a block. Some boundaries are hidden for visibility.

In the Mesh toolbar, click Create Geometry () or right-click and select it from the The Graphics Context Menu.
The COMSOL Multiphysics software creates a new model Component of the same dimension as the current mesh. The geometry sequence in the new component has an Import node that imports the original mesh as geometry.
Reusing the Original Mesh
It is sometimes possible to use the original, imported mesh, or parts of it, in the new Component.

Add a Copy () operation to the meshing sequence.

Click the Copy button to copy the mesh. If you have added more geometry, you can use the usual mesh operations to add mesh to these entities. You can also add boundary layers to the copied mesh.
