IIHS 2.0 Model

GNS IIHS 2.0 Crash Barrier

In 2021 CDH AG acquired marketing, sales and support rights from GNS mbH to distribute the GNS FEA barrier models in America, Europe and Asia. GNS mbH is a specialist in the development of high-quality FE software solutions (e.g. GNS Animator4) and FE models for vehicle safety analysis. Since more than 20 years, GNS mbH develops highly accurate FE Crash Barrier models in close cooperation with the German and other world-wide automobile industry partners. GNS Crash Barrier FE models are used in the virtual development process for passive vehicle safety engineering calculations.

Initial setup of IIHS barrier model according to the IIHS specification

  • Adjusted block stiffnesses with prescribed performance corriido

  • Two versions are available, considering enabled or disabled gravity in your simulation.
  • Model mass, velocity and boundary condition is adjustable by LS-Dyna *PARAMETER

IIHS 2.0

Easy Adjustable

By setting *PARAMETER GNS_MASS, GNS_XVELO, GNS_FIX the barrier model integrates perfectly in your simulation.

Basic features


The barrier models was calibrated using several hardware tests with vehicle like lateral structures as impact bodies in different positions.

Basic features


Adhesive beams, gluing honeycomb to cladding sheets are able to fail according load.

Basic features


Two versions of the IIHS model are available, considering enabled or disabled gravity in your simulation.

Basic features

Pressure Air Wheels

Trolley wheels with tires of pressure air, getting model motion closer to reality.
