User-Controlled Mesh Clustering (Sources)

CENTAUR allows the user to specify mesh clustering in regions of interest.

Capabilities:

  • Local control of mesh sizes
  • Local use of anisotropic (stretched) elements

A smooth size transition is ensured for multiple length scales.

Geometric Source Shape Examples:

Some typical source types are shown below:



  • Sphere

  • Hexahedron (Box)

  • Cylinder

Example: Surface Clustering Source

No Sources Two Cylindrical Sources
9640 faces 13830 faces

Example: Anisotropic Surface Source

Isotropic Elements Anisotropic Elements
No Sources
9640 faces		 1 Anisotropy Source
3280 faces (66% fewer)

Example: Prismatic Curve Source

A prismatic curve source has been added to the leading edge to locally reduce the prism thickness.
