Improving Smoothed Aggregation AMG Robustness on Stretched Mesh Applications
Chris Siefert, Raymond Tuminaro, Daniel Sunderland
Strength-of-connection algorithms play a key role in algebraic multigrid (AMG). Specifically, they determine which matrix nonzeros are classified as weak and so ignored when coarse…
