Ansys Workbench LS-DYNA

This course covers the use of Ansys LS-DYNA® nonlinear dynamics structural simulation software inside Ansys Mechanical™ structural finite element analysis software. Ansys LS-DYNA software is useful for the analysis of problems involving contact, large deformation, nonlinear materials, transient response, and/or problems requiring explicit solutions. Common applications for which Ansys LS-DYNA software excels include safety and stability, crash test and drop test simulation, as well as forming applications.

Learning Outcomes:

Following completion of this course, you will be able to:

• Understand how the explicit solution method differs from other methods used to performed dynamic analysis in Ansys and to choose when it is most appropriate.
• Choose the proper solution parameters unique to Ansys LS-DYNA software that will ensure an accurate and efficient solution.
• Take advantage of common modeling abstraction techniques (rigid bodies, point and distributed masses) to produce efficient and realistic simulations.
• Understand and apply various Contact conditions unique to Ansys LS-DYNA software according to best practice guidelines.
• Leverage the robust nonlinear analysis capabilities afforded by Ansys LS-DYNA software in the solution of quasi-static problems.
• Assign mesh controls required to produce accurate and efficient explicit solutions.
• Choose from several Ansys LS-DYNA software element formulations while understanding the trade-offs between accuracy and efficiency. Use SPH to solve problems involving granular or fluid-like materials.
• Access advanced functionality of Ansys LS-DYNA software using keyword snippets.

Prerequisites:

• Ansys Mechanical: Beyond the Basics
• If you have not done analysis using Ansys LS-DYNA software, then we recommend you taking Ansys Workbench LS-DYNA Getting Started first.
