PDF tutorial with Explicit Dynamics FEA of the impact between a bowling ball and its pins; 53 pages in which we learn: - to edit the 3D model to obtain shell elements - to mesh in a simplified manner, for faster solving time - to define proper Analysis Settings correlated with the nodes and elements number - to define proper output for deformation, stress, velocity etc. - to properly observe the solver's response - to parameterize the input data for automatic solving of multiple FEA scenarios in the same file
