Implicit Roof Crush

This problem demonstrates the ability to solve a complex, highly dynamic and nonlinear problem using the implicit solver of LS-DYNA. The model runs robustly and can be used as a learning aid for setting up implicit problems. The original car model of the Toyota Camry was taken from the NCAC FE model database. Please use a recent developer version of LS-DYNA (i.e. ls-dyna_mpp_d_dev_109569 or later) to compute this example.
