![]() ![]() COMSOL Multiphysics automatically adds a Mesh Part node (under the Global Definitions node) that imports the mesh file and creates a geometry from the imported mesh. Simply add an Import subnode under the Geometry node, browse to the mesh file to import, and click on the Import button. The process of importing an externally defined mesh (e.g., a surface mesh defined by an STL file) as a geometry is now easier and more robust. This means that the operation can partition output geometries before or after performing Form Union/Assembly, Assembly Geometries, and Virtual Geometries operations. Furthermore, it can increase the level of (shared-memory) parallelization during meshing.Ī Partition Domains node can be placed at any position in a list of subnodes under the Geometry node. Partitioning can also be an important tool when building tetrahedral meshes by subdividing a complex-shaped (highly nonconvex) domain into domains that are easier to mesh. It can be useful in cases where it would be better to mesh a certain part of the geometry with a structured mesh instead of an unstructured mesh, but the domains are not suitable for mapped or swept meshing. This function serves multiple purposes when modeling. This extends a face into the adjacent face of a domain in order to partition that domain. For example, you can partition the domain of a 3D geometry by the extensions of selected faces of the geometry. ![]() A new geometry operation, Partition Domains, enables you to partition selected domains in various ways in 2D and 3D by specifying curves and surfaces, respectively. ![]()
