Uncertainty in simulations of a shaped charge jet device is quantified using an approach established in a prior study of a long rod penetrator. The focus of this study is on computational factors, such as domain structure, coordinate system placement, and object orientation. Depth of penetration of the jet into a solid steel block is the primary quantity of interest, with computational time being a secondary metric. Current versions of two different simulation codes, CTH and ALEGRA, are examined.
