An Angular Method with Position Control for Block Mesh Squareness Improvement
- Lawrence Livermore National Lab. (LLNL), Livermore, CA (United States)
We optimize a target function de ned by angular properties with a position control term for a basic stencil with a block-structured mesh, to improve element squareness in 2D and 3D. Comparison with the condition number method shows that besides a similar mesh quality regarding orthogonality can be achieved as the former does, the new method converges faster and provides a more uniform global mesh spacing in our numerical tests.
