Side Crash Simulation of Chrysler Neon BIW
Objective: In this project, I will run a side crash simulation of a Chrysler Neon BIW model. A cylindrical rigid wall with a diameter of 150 mm is placed next to the left B-Pillar of the BIW and the initial velocity of the BIW is set to be 35 mph = 15.56 m/s. In this simulation, the pre-processing is carried out by HyperMesh…
