摘要: In this paper, a new three-level explicit difference scheme with high-orderaccuracy is proposed for solving three-dimensional parabolic equations. The stabilitycondition is r=△t/△x2 =△t/△y2=△t/△z2≤1/4, and the trumcation error is O(△t2+△x4).

关键词: high-order accuracy, explicit difference scheme, threedimensional parabolic equation
