Offset Deformable Barrier Crash Tesh + Occupant + Airbag

I have tried to create a car crash simulation, complete with occupant and airbag. So far far it is running just fine. However, this simulation does not simulate the actual crash test since the step time is increased beyond acceptable level (mass scaling).

Optimization of Airbag

The video uploaded show you one of the simulated iterations. It is optimized using Ls-Opt.

BIW Reinvent

Restarting the development of new concept car. Currently trying to reinvent the whole BIW from scratch. Attached figures are the original BIW for reference (still incomplete).
