Direct Calculation of Self-Gravitational Force for Infinitesimally Thin Gaseous Disks Using Adaptive Mesh Refinement
Yao-Huan Tseng, Hsien Shang, Chien-Chang Yen
Yen et al. (2012) advanced a direct approach for the calculation of self-gravitational force to second order accuracy based on uniform grid discretization. This method improves the…

Self-gravitational Force Calculation of Second Order Accuracy Using Multigrid Method on Nested Grids
Hsiang-Hsu Wang, Chien-Chang Yen
We present a simple and effective multigrid-based Poisson solver of second-order accuracy in both gravitational potential and forces in terms of the one, two and infinity norms. Th…
