Therefore, it would be prudent to decompose the domain into parallel strips that run perpendicularly to the crash front so that each processor has a similar number of elements in the crash front. For example, in a car crash analysis, inelastic deformation is expected to occur at the crash front region. A decomposition that partitions the region of the expected inelastic behavior among the available processors, if possible, can benefit the performance of the analysis. This is especially true when material inelasticity occurs since the modeling of the inelastic behavior is in general more computationally demanding (i.e., involves a higher number of operations) than the elastic behavior. A good domain decomposition can improve the efficiency of an MPP analysis.
