LS-Dyna

GiD LS-Dyna Interface is an application acting as a bridge between the Pre/post processing program GiD (Custom GiD) and the commercial nonlinear dynamic solver LS-Dyna.

LS-Dyna is a general purpose finite element code used to analyze the large deformation response of structures (including structures coupled to fluids). Specialized capabilities for airbags, sensors and seatbelts have tailored LS-Dyna for applications in the automotive industry.

GiD LS-Dyna Interface, which is compatible with GiD 9 and LS-DYNA v. 971, provides a completely graphical environment for several types of structural simulations. However, the product is focused on crash test problems and necessary tools for seatbelt and airbag definitions have been implemented.

GiD LS-Dyna Interface is powered by a new Toolkit for problem types creation (developed by Compass). Thanks to this new system, problem data is always displayed on the left of the screen during Pre and Post-Processing and the Interface is based on groups’ concept. A group is a list of geometrical or meshing entities that are referenced by one or several conditions, and the Toolkit provides the user all the tools to manage and edit them.

On one hand, Experienced users will find a revolutionary way to define structural problems with LS-Dyna, taking profit of GiD user-friendly behaviour. Problem edition will be easier than ever and all GiD Pre and Post-Processing tools are also available.

On the other hand, Beginners will find an application with a very intuitive way to completely analyse a structural problem.

Interface capabilities:

• Handles discrete, beam, shell, solid, seatbelt and airbag elements.

• Several material types vailable (elastic, rigid, isotropic, anisotropic, fabric, plastic, viscoelastic, springs, dampers, etc.).

• Single and Master & Slave contacts definition.

• Dynamic loads and constraints.

• Several Joint types available (spherical, revolute, translational).

• Fully GiD postprocessing functionality.
