Mesh

Simcenter STAR-CCM+ provides a complete set of capabilities for both surface and volume meshing operations.

Mesh Topologies
  • Surface: triangles, quadrilaterals, polygons
  • Volume: tetrahedra, hexahedra, prisms, arbitrary polyhedra
Mesh Framework
The Simcenter STAR-CCM+ mesh framework provides a flexible environment and repeatable processes. The general features of the framework are:
  • Sequencing and re-ordering of mesh operations
  • Serial, concurrent per part, and parallel mesh generation
  • Local mesh modification of wrapped and remeshed surfaces
  • Conformal polyhedral and tetrahedral meshes across multi-part assemblies
Surface Meshing
The surface meshing tools in Simcenter STAR-CCM+ are designed to provide high quality triangulations on arbitrarily complex and dirty geometries. Available surface meshing tools include:
  • Surface preparation: to manually repair and prepare surfaces ready for meshing (quads and triangles)
  • Surface wrapper: to provide a closed, manifold, non-intersecting surface when starting from poor quality CAD data
  • Surface remesher: to provide a high quality starting surface for all volume mesh types
  • 2D mesher: to create triangular and polygonal meshes on 2D geometries
Volume Meshing
Simcenter STAR-CCM+ provides automatic volume mesh generation with optimized cell quality for arbitrarily complex geometries. Volume meshers include core general meshers as well as meshers designed for particular geometries such as long pipes or thin regions.
