The Mesh module provides a set of tools that allow you to refine a mesh.
You can use the Partition toolset to divide geometric regions into smaller regions. The resulting partitions introduce new edges that you can seed; therefore, you can combine partitioning and seeding to gain additional control over the mesh generation process. You can also use partitioning to create regions to which you can assign different element types. For example, you might want to assign reduced-integration elements to some portions of your model and fully integrated elements to others. For more information, see Chapter 70, “The Partition toolset.”
In some cases the geometry contains details such as very small faces and edges. The Virtual Topology toolset allows you to remove these small details by combining a small face with an adjacent face or by combining a small edge with an adjacent edge. Introducing virtual topology is a convenient method for creating a clean, well-formed mesh. For more information, see Chapter 75, “The Virtual Topology toolset.”
You can use the Edit Mesh toolset to make minor adjustments to your mesh. For more information, see “What can I do with the Edit Mesh toolset?,” Section 64.1.
