| Abstract: | Finite-difference methods with high-order accuracy have been utilized to improve the precision of numerical solution for partial differential equations.However, the computation cost generally increases linearly with increased order of accuracy.Upon examination of the finite-difference formulas for the first-order and second-order derivatives, and the staggered finite-difference formulas for the first-order derivative, we examine the variation of finite-difference coefficients with accuracy order and note th... |
| Keywords: | finite difference high-order accuracy truncation efficiency numerical modeling |
