Creating Geometry from Mesh

A mesh imported into COMSOL Multiphysics can be used to construct a geometry. A situation in which this is useful is when you need to add more geometry (for example, a bounding box to mesh the surrounding of the imported mesh object), or if you want to modify the imported mesh (for example, by adding boundary layers).

1	Select the mesh part or meshing sequence with the imported mesh.

2	On the Mesh toolbar, click Create Geometry from Mesh () or right-click and select it from the context menu.

The COMSOL 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 possible to use the original, imported mesh, or parts of it, in the new Component.

1	Add a Copy feature to the meshing sequence.

2	Select the original import sequence as Source Mesh.

3	Select source and destination entities.

4	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.
