This research aims to develop a fictitious domain method based on finite volume discretization. The main idea is to add a source term in the momentum equation, which can apply rigid body constraint on domains covered by particles. The source term includes both particle and fluid information inside. It shows that by refreshing fluid information after each iteration, rigidity of solid can be preserved. This finite volume method is then verified by simulations of several cases and comparing results with literatures, which proves accuracy of the method.
