COMSOL Multiphysics along with its LiveLink™ for MATLAB® is used to investigate the needed number of elements and the required order of Lagrangean p element for a number of different simulation models. For this task, convergence study, speed up testing and interactive meshing is performed on a large assembly model which is also imported using the LiveLink™ for SolidWorks®. As a test bench, the famous Flyer Model is selected and the Speed ups for different solvers are provided for the evaluation of the parallel computation performance. Finally, for large assemblies, we noticed the parallel computing performance is strongly dependent on the solver settings, the meshing technique, the element type used and slightly on the imported CAD product format.
