Creating Geometry from Mesh
A mesh imported into COMSOL Multiphysics can be used to construct a geometry. It is recommended to use such an object only as an aid Create a geometry object of the mesh, marking it as Construction Geometry, to use it as an aid when positioning the geometry, as shown in the suggested tutorial below.
Figure 8-26: Importing the mesh of the vertebrae and disc into the geometry sequence as a construction object to help with the positioning of the geometry.
If the goal is to improve the quality of the imported mesh, it is recommended to remesh the faces in the meshing sequence, without creating a geometry. See Remeshing Imported Meshes for more information.
Boolean operations when one or more of the parts originate from mesh are much more stable to build in the meshing sequence. Import any geometry to the meshing sequence and use a mesh Union operation to unite them in the meshing sequence. See Importing Geometry to Mesh.
To create a geometry from a mesh, choose one of the following:
•
Add an Import node to the geometry sequence and browse to import any supported mesh file.
•
Select an existing mesh part or meshing sequence. In the Mesh toolbar, click Create Geometry () or right-click and select it from 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.
