SpaceClaim Course, Session 22: Spaceclaim Meshing

SpaceClaim Meshing is one of the most important environments in this software, because it allows you to generate high‑quality meshes without needing to switch between separate meshing tools such as Ansys Meshing or Fluent Meshing. In this session, you will learn how to create accurate and clean meshes using the SpaceClaim mesh controls. We will begin with simple geometries and basic operations, and then proceed to generate an O grid mesh for a cylindrical pipe flow case. By the end, you will be able to build structured, CFD‑ready meshes directly inside SpaceClaim.

2. Mesh Quality

To generate a more accurate and reliable mesh, different techniques should be used to improve mesh quality. One practical approach is to locally edit the mesh size in critical regions to correct poor quality cells. In addition, in many cases the quality can be enhanced by splitting geometry faces, which helps SpaceClaim build cleaner blocks and therefore produces a better quality mesh.

3. O-grid Mesh

Generating O-grid meshes is also available in SpaceClaim Meshing and one of its advantages is that you do not need to manually create the central block inside the circle. Instead, the software automatically generates this block simply by selecting the relevant curves of the geometry.

4. Summary

This session introduced how to use SpaceClaim Meshing to create high‑quality structured and O‑grid meshes for internal pipe‑flow problems. The workflow covered basic geometry preparation, edge sizing, biasing, and layer generation around cylindrical walls. It also emphasized mesh‑quality improvement through local sizing edits and face splitting to obtain cleaner blocks. Finally, the process of checking mesh quality and exporting the mesh for CFD solvers was outlined as the last step.
