摘要: 对解三维热传导方程利用待定参数方法构造出一种精度O(Δt2+Δx4+Δy4+Δz4)的高精度易于计算的显式差分格式,并给出了其稳定性,通过数值例子可见其精度较其它方法提高2~3位有效数字。Abstract: In this paper,an explicit three-level symmetrical differencing scheme with parameters for solving parbolic partial differential equation of three-dimension will be considered.The stability condition and local truncation error for the scheme are r<1/2 and O(Δt2+Δx4+Δy4+Δz4),respectively.
