Internal:Metric Adaptive CDT3D
Delta Wing (Scitech 2018)
Cube (polar-2 metric) (Scitech 2018)
This approach offers no boundary adaptation.
General Notes
- smoothing : Tetrahedral Mesh Improvement Using Swapping and Smoothing, Lori A. Freitag and Carl Ollivier-Gooch PDF
- An Efficient Method to Solve the Minmax Problem Directly, C. Charalambous and A. R. Conn PDF
- Comparison for quality criteria for ACDT3D
Stability for 500k case
Comparison of Quality Metric using different amount of cores and surface adaptation
Comparison of Quality Metric using different amount of cores and mesh reconstruction
Comparison Surface Adaptation vs Mesh Reconstruction (reproducibility)
TODO needs update
Surface adaptation offers better edge lengths but mesh reconstruction slightly better mean ratio quality
Need update
50k Complexity
Starting from a coarse surface mesh
TODO needs update

Notes 1
- Speed 22.5K test/sec and 3.9 ps/sec
- according to Mike's email mesh should be around 100k vertices
- Metric Input Data available at https://github.com/UGAWG/parallel-adapt-results
- Input surface is the coase mesh available at https://github.com/UGAWG/solution-adapt-cases
- The experiments performed on a DELL workstation with Linux Red Hat Enterprise, 24 hardware cores Intel® Xeon® CPU E5-2697v2@2.70 GHz, and 757 GB RAM
- Memory is measured at the end of Mesh refinement and thus it may reach a slightly higher value before the point of measurement
