Refinement - Coarsening

Local refinement - coarsening can be applied for all element types; hexahedra, prisms, tetrahedra and pyramids. It is automatic and based on field sensors. A wide range of sensors is available. The user can also specify his/her own. The quality of the resulting mesh is monitored and enhanced.

 

Surface Fidelity

The adapter ensures that the fidelity of the CAD surface is maintained throughout the refinement process.

CAPABILITIES:

New surface nodes match CAD surfaces exactly
 
Mesh validity is ensured

Original Mesh Refined Mesh

 

Adaptive Local Mesh Division Example

This example shows the mesh before and after solution-based refinement. Extra clustering is added along the leading and trailing edge of the wing as well as around the engine inlet via the adaptive local mesh division process.

Original Mesh

Refined Mesh

 

Transonic Flow on a Wing

The original mesh is refined automatically in the location of a standing lambda shock on this transonic wing. The yellow mesh shows the extra refinement on the surface.


Refinement Example

The white lines show the original mesh and the green lines show the refined (and redistributed) mesh. Note that the prism stacks have been directionally refined maintaining the layer structure.


Leading Edge Surface Matching

This example shows refinement at the leading edge of a blade demonstrating that new points are placed onto the original surface. The white lines show the original mesh and the green lines show the refined mesh. Note the substantial motion in the lower portion of the leading edge.
