Abstract

Abstract: In this paper, a class of explicit difference schemes with parameters for solving five-dimensional heat-conduction equation are constructed and studied. the truncation error reaches O(τ²+h⁴), and the stability condition is given. Finally, the numerical examples and numerical results are presented to show the advantage of the schemes and the correctness of theoretical analysis.

Key words: heat-conduction equation, explicit difference scheme, truncation error, conditional stability
