The tests are a partial subset of the full set of tests run by Ansys developers to ensure a high degree of quality for the LS-DYNA product. The verification of the LS-DYNA product is conducted in accordance with the written procedures that form a part of an overall Quality Assurance program at Ansys.
Ansys has verified the solutions for the LS-DYNA test cases. Although some differences may exist in comparison to the reference solutions, the differences have been examined and are considered acceptable. The analyses seek a balance between accuracy and solution time. The general goal is an error of three percent or less. In some cases, you can improve the results (at the cost of longer solution times) by using a more refined finite element mesh.
Test Platform
The Ansys verification team ran these tests using Microsoft Windows 11, 64-bit and reported the results in the test documentation. You may see slight differences in the results if you run the tests on different processors or operating systems. You can use these tests to verify that your hardware is operating correctly. You can clear the results in the databases and run the tests multiple times. For each test, you should check the test results against the verified results in the documentation.
There are two types of tests included in this Verification Manual: Workbench-based and solver-based test cases:
Workbench-based LS-DYNA tests: The LS-DYNA Workbench test cases and the LS-DYNA Benchmark test cases use the Workbench version of LS-DYNA. These tests create the model, apply loads, solve, and evaluate results within Ansys Mechanical.
Solver-based LS-DYNA tests: The remaining test sets were solved using LS-DYNA file .k inputs that were run directly by the LS-DYNA solver. These sets include the LS-DYNA Solver test cases, the LS-DYNA EMAG test cases, and the LS-DYNA Fluids test cases.
