This example shows the static loading of the TOYOTA Yaris suspension system. The car model is based on the CCSA (former NCAC) TOYOTA Yaris. The author’s aim is to do as less modifications as needed to make the model ‘implicit ready’. This model was computed successfully with the LS-DYNA R9.0.1 MPP implicit static solver. Last but not least we want to acknowledge the CCSA for the baseline model.
