High Order (Curved) Grids
CENTAUR can create quadratic (curved edge) hybrid meshes for increased solution accuracy with reduced number of elements. The curved mesh edges conform to the geometry. The quadratic meshes are well suited for a large number of curved parts, such as pipes and holes.
The high order meshes can be exported via various formats including CGNS. A direct interface to SU2 solver is also available.
ROBUSTNESS AND QUALITY FOR COMPLEX GEOMETRIES:
- Quadratic elements especially for boundary layer regions
- On-the-fly quality control
Examples
Quadratic elements are primarily used for curved boundaries. The linear and quadratic grids for a sector of an annular tube with a pipe and the leading edge of a wing are depicted below:
