Abstract (in Japanese) (See Japanese page) 
(in English) Simulations of behaviors of water as liquid are quite important in the fields of video pictures and disaster analysis and prediction．These simulations require much calculation time due to complicated evaluation governing equations．In this paper， we propose a method to accelerate two-dimensional water simulation by FPGAs．We use the PROGRAPE (Programmable GRAPE proposed by RIKEN) as a calculation platform．We adopt SPH (Smoothed Particle Hydrodynamics) method to simulation of fluid behaviors because this method can simulate dynamic fluid flows with large deformations．In the simulation by software，evaluation of the motion equation is complex and needs much more time．Therefore we design the circuit of the motion equations． Moreover， we evaluate the minimum calculation accuracy for circuit．By these evaluations，we confirmed that the liquid simulation on the PROGRAPE system is faster than that on software．
