Anisotropic meshing is available in both 2D and 3D to support:
- Boundary layers, and
- Multiple elements across thin sections.
- Input is a triangular mesh in 2D or a tetrahedral mesh in 3D.
- Boundary layers are formed using a special point insertion method
- Resulting anisotropic mesh is optimized and smoothed, keeping
boundary layer elements intact.
- Methodology is similar to that of boundary layers.
- Input is a triangular mesh in 2D or a tetrahedral mesh in 3D,
as coarse as possible.
- Points are inserted along mesh edge paths in the thin sections.
- Standard insertion is then applied to conform to given mesh density.
- Optimization and smoothing maintain the multiple layer elements intact.
