Upcoming Courses

Introduction to explicit structural mechanics with LS-DYNA

This seminar provides the theoretical foundation and the practical application of LS-DYNA for nonlinear dynamic and quasi-static analyzes (such as crash, impact, drop test, limit load and metal forming). The attendees learn the model setup with ANSYS Workbench LS-DYNA. In addition, model editing and postprocessing with LS-PREPOST is shown.

  • Introduction to LS-DYNA and its workflow
    • Typical application areas for LS-DYNA
    • Overview of essential components of the program
    • Integration of LS-DYNA into ANSYS Workbench: ANSYS Workbench LS-DYNA
    • Basics of LS-DYNA: explicit vs. implicit time integration and consequences
    • Stability of time integration method and control of time step size, mass scaling
  • Aspects of FE-Modelling
    • Basics of the FEM-Discretisation for LS-DYNA and fundamental meshing rules
    • Available finite element formulations (element integration, hourglass forms)
    • Modelling in Workbench LS-DYNA
    • LS-DYNA Keyword format
    • Model editing in LS-PREPOST
  • Execution of simulation
    • Necessary and important control options of calculation; recommendations
    • Influences on simulation speed and accuracy
    • Control of output data; available result files
  • Evaluation of simulation results
    • Graphical representation as contour plots and animation
    • Create and manipulate time history diagrams
    • Important and necessary result controls
  • Modification and completion of exercises
    • Workbench LS-DYNA examples for dynamic and quasistatic analysis

This seminar provides an introduction into the explicit transient simulation with Workbench LS-DYNA. It is designed for simulation engineers, who would like to use LS-DYNA for the analysis of non-linear, dynamic problems. Tasks, which are typically simulated using LS-DYNA are for example crash, impact, drop test, limit load analysis and metal forming, or other highly nonlinear problems. Besides teaching the workflow around Workbench LS-DYNA and the presentation of basic knowledge, the acquired knowledge is strengthened by individual training and completion of practical examples.
