Ansys Mechanical Benchmarks

Ansys Mechanical Benchmarks

This benchmark suite provides Ansys Mechanical hardware performance data measured using sets of benchmark problems selected to represent typical usage. The Ansys Mechanical benchmark cases range in size from 650,000 degrees of freedom to over 14 million degrees of freedom. The suite contains both PCG and Sparse equation solver benchmark cases as well as covering a wide variety of analysis types including static, transient, modal, cyclic symmetry modal and harmonic. Additionally, both thermal and structural physics are covered. These cases are used by hardware vendors to benchmark their hardware systems and the resulting performance data is then included in these pages. For further descriptions of benchmark problems, please go to the benchmark page related to the case you are interested in.
