Introduction to ANSYS Workbench/ LS- DYNA

Prerequisites

B.S. in engineering or engineering experience.

Description

The ANSYS Workbench environment is an intuitive up-front finite element analysis tool that is used in conjunction with CAD systems. LS-Dyna is an explicit finite element code that is used for solving short duration transient and highly nonlinear quasi-static analyses. ANSYS Workbench/LS-Dyna combines the preprocessing power of Workbench with the LS-Dyna solver.

This class includes training on how to use Workbench tools to attach and modify geometry for finite element modeling, meshing methods for explicit dynamics analysis, applying loads and constraints, generating and assigning material models, editing LS-Dyna files, solving with LS-Dyna, and reviewing results. Basic finite element simulation concepts, explicit method theory, and results interpretation will be discussed.

Learning Objectives

The goal of this class is to provide students with the ability to perform the following tasks:

  • Navigate the Workbench project page to configure structural static and explicit dynamics analyses.
  • Use the Engineering Data page to enter linear and nonlinear material properties.
  • Use DesignModeler to import, create, and modify geometry for use in subsequent finite element analysis.
  • Use DesignModeler to simplify or defeature CAD geometry.
  • Use the Workbench/Mechanical interface to mesh the geometry, apply loads and boundary conditions, assign contact interfaces, and set up solution controls.
  • Learn how to create meshes that provide a balance of accuracy and speed for LS-Dyna analyses.
  • Learn the basics of finite element theory, implicit and explicit time integration methods, and gain insight into how to create and analyze models that produce accurate results.
  • Use the explicit dynamics (LS-Dyna) features in Workbench to set up models for short-duration transient analyses.
  • Edit LS-Dyna input files to add specific commands to your models.
  • Use the LS-PrePost post-processor to plot and evaluate LS-Dyna results.
