Methods and systems for applying mass scaling in finite element analysis is described. Elements with a critical time step smaller than a user desired time step are identified. Out of these elements, elements located in a particular region requiring realistic simulated dynamic responses are processed with selective mass scaling and the rest are processed with regular mass scaling. Selective mass scaling requires more computation but can better preserve dynamic structural characteristics. The aforementioned method is referred to as a mixed mode mass scaling. Mixed mode mass scaling allows engineering simulation to be conducted within a reasonable turnaround time, because only a portion of the FEA model is subjected to more computation intensive selective mass scaling. Selective mass scaling technique includes reducing effects caused in three translational and three rotational rigid body modes of shell element.
