For computational fluid mechanics simulations of a three-dimensional photoelectric semiconducting detector, a modified upwind finite difference fractional step scheme was proposed. The optimal error estimated by using techniques including calculus of variations, energy method,induction hypothesis, and a prior estimates were obtained. The proposed scheme has been applied to simulate the photoelectric semiconducting detector.
