SpaceClaim Course, Session 25: SpaceClaim share topology

Description

1. Introduction

SpaceClaim share topology is a very practical option in SpaceClaim that directly affects your mesh generation. Overall, share topology is a geometric operation that makes touching bodies share the same faces and edges at their interfaces. When this is done, the mesh on both sides of the interface becomes conformal.

2. Objectives

To clearly show how SpaceClaim share topology works, we will create a simple geometry and mesh it in two different ways. In one case we will generate the mesh after applying the share topology operation, and in the other case we will mesh the same geometry without using this command. In the case without share topology, the inner and outer regions do not share nodes, so the interface is non‑conformal and the two meshes are independent. In the case with share topology, the interface faces are shared, so nodes line up on both sides and you get a single continuous, fully conformal mesh across the geometry.

3. Summary

Creating a conformal mesh is crucial for many CFD simulations because it guarantees continuity of the solution across shared interfaces. SpaceClaim share topology is therefore very important, as it provides the core mechanism for generating this type of mesh. In this session, the goal was to practically demonstrate different ways of sharing geometry and to show how applying or not applying this command changes the final mesh result.
