110% Ansys LS-DYNA – Perform Explicit Analyses Efficiently
Includes current features and best practice tips
In this training, you will deepen your knowledge and learn procedures & tricks for solving various simulation tasks with LS-DYNA in the Workbench. This training is offered as a 2-day course.
Duration
2 days
Prerequisites
Knowledge of Workbench LS-DYNA
Software used
Ansys LS-Dyna
- Benefit from our experience in support, training & consulting
- Learn about the new features of Workbench LS-DYNA and how to use them
- Understand and optimize LS-DYNA specific workflows
- Practical tips for detailed post-processing
Description
This training focuses on the application of LS-DYNA within the Ansys Mechanical environment and the specific LS-DYNA tools provided. The topics deal with the handling of prestressed components, the efficient implementation of multiple load cases, specific meshing methods and procedures for post-processing of selected quantities. Using application-related examples, the various possibilities for using the LS-DYNA solver to solve transient processes are demonstrated. Moreover, possibilities for implicit calculations or modal analyses are described. In addition to the development and understanding of workflows for explicit analyses, you will receive numerous tips for their optimal use in everyday simulation.
This training is aimed at computational engineers who are familiar with Ansys Workbench, who have already gained initial experience with LS-DYNA and who want to learn about the extensive possibilities of using Workbench LS-DYNA to solve a wide range of structural dynamics tasks.
