A series of calculations of the MIXED COMPANY event was performed using the Weidlinger Associates LAYER code. The calculations incorporated preshot and postshot models obtained jointly by Weidlinger Associates and the Waterways Experiment Station. The results of the postshot computations are presented and compared to the measured field response and to the preshot calculations. Although the postshot results are in slightly better agreement with the field data than were the preshot results, there remains considerable disagreement between all the computations and the data, especially as far as outrunning and crater induced motions are concerned. Possible explanations for the discrepancy and recommendation studies to correct them are presented.
