In this talk, we focused on the self-gravitational force
calculation of initesimally thin and bounded distribution of surface density in 3-D space. The method we proposed is to expand the surface density function based on B-spline function, and calculated the B-spline function and kernel integration by integral formula directly. The numerical simulations demonstrate the proposed method is high order accuracy and fast calculation.
