Updated shell standard-problem and flat-punch calculations are still being checked. Their results are not included in this comparison set.
What the comparisons establish
Analytical solutions, published benchmarks and solver-to-solver checks answer different questions. Results apply to the configurations shown, not every feature or workload. Runtime comparisons have their own performance conditions.
