Using MSC Nastran 103 to calculate BIW (car's sheet metal platform only)resonance frequency by FE method, do we need to apply any constrains?
I think, a free modal analysis means no constrains, however, final outcome (Hz)will depends on where forces are applied to the model ? Cross car torsional stiffness frequency will be diferent from front to back. Please, advise.
