Combining Geometry and Mesh
Combining mesh, for example imported from an STL file, and geometry, either drawn in the software or imported CAD, can be done in two ways. Either by Importing Geometry to Mesh and combine them using mesh operations, or by Creating Geometry from Mesh and combine them using geometry operations. Regardless of which method you choose to follow, COMSOL Multiphysics supports a variety of operations, for example:
•
Moving, scaling, and rotating the imported mesh
•
Combining the imported mesh with parameterized geometry to run parametric sweeps
•
Intersecting imported meshes with each other
•
Modifying and remeshing the imported mesh
•
Generating a tetrahedral mesh in unmeshed domains
•
Generating a swept mesh in unmeshed domains
•
Creating a boundary layer mesh
•
Using curved mesh to represent curved boundaries
Working with the mesh directly can be more robust in case you need to intersect several imported meshes (or intersect the imported mesh with geometric objects of more complex shapes). This can be important to consider when choosing whether to create a geometry or not.
