Local Control (Sources) – CENTAUR Software

User-Controlled Mesh Clustering (Sources)

CENTAUR allows the user to specify mesh clustering in regions of interest. A smooth size transition is ensured for multiple length scales.

 

CAPABILITIES:

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

Some typical geometric source shapes are shown below:

Example: Prismatic Curve Source

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

Example: Aircraft with Cylinder-shaped Source Behind the Engine Nacelle

The mesh in the wake tetrahedra region is clustered using a cylindrical source with varying radius in the axial direction.
