LS-DYNA Compact: Implicit Analysis using LS-DYNA (2 Parts)

In recent years, the simulation possibilities in LS-DYNA using
implicit time integration have been enhanced extensively. The main
areas of application for implicit analyses include linear and
non-linear static computations, natural frequency analyses, springback,
lengthy transient simulations, systems with preload, etc. The aim of the
webinar is to give participants an overview of the possibilities and limits
of implicit simulations using LS-DYNA. In particular, attention will be
drawn on the required input cards for such simulations.

The seminar is recommended for engineers intending to use LS-DYNA to
carry out implicit simulations. In addition, experienced “explicit users”
learn about what to bear in mind when converting explicit into implicit input
decks. Examples will be given during the seminar to illustrate the
functionality of the implicit options.

Note that this webinar is a condensed version of our attendance class "Implicit Analysis using LS-DYNA".

- Input syntax for implicit control cards
- Linear static analysis: options, linear elements, boundary constraints, direct/iterative solvers, accuracy
- Dynamic analysis: Newmark method, input parameters, lumped/consistent mass matrix
- Nonlinear analysis: solution methods (Newton, BFGS, arclength), convergence, tolerances, output, automatic step size strategy
- Eigenvalue analysis: options, modeling aspects, intermittent output
- Element types for implicit: linear and nonlinear elements
