When FLACS is applied to conduct the numerical simulations of large gaps with sizes approaching one or two times of the module size, a large error in the overpressures in the acceptor module is observed. In this chapter, a data-dump technique is developed to address this issue. The overall results indicate that the data-dump technique is very effective for the evaluation of gas explosion overpressures in areas with large separation gaps.
