Simulation Code LS-DYNA R9.0.0
Analysis Type FEA
Description This is a modified version of the car2car benchmark supplied by Dr. Tsay, LSTC. It has been shortened to have an end time of 0.01s. This model uses a NCAC minivan model created by Dr Makino and analyses a head-on collision between 2 vehicles with initial velocities 15.64m/s and -15.64m/s respectively.
Suggested Hardware Onyx / 18 cores
Command
ls-dyna -i Caravan-V03c-2400k-main-shell16-10ms.k -p single
Estimated Run Time 60 minutes

Simulation Code LS-DYNA R9.0.0
Analysis Type FEA
Description This is a 3 car collision simulation, where a compact car is hit from the rear by a van and collides into a midsize car. This is a modified version of the simulation which was shortened to have an end time of 0.020s. NCAC is responsible for the vehicle models and this simulation was put together by Mike Berger, consultant to LSTC.
Suggested Hardware Onyx / 8 cores
Command
ls-dyna -i 3cars_shell2_20ms.k -p single
Estimated Run Time 22 minutes
