# Surface Mesh

The surface mesh represents the discretized object boundary.

This section covers the fundamental aspects of surface mesh handling and its components.

A surface mesh in Flow360 consists of surface elements in three-dimensional space that discretize the objects surface. The mesh structure is defined by:

  • Boundaries: Surfaces that define the edges of computational domains and interfaces between zones

# Mesh Requirements

Flynn360 volume mesher supports surface meshes with triangular surface elements.
