以混凝土热传导方程为基础,通过数学推导,建立其内部与边界的一维差分格式,并对具体情况进行了差分求解,通过与理论解对比分析,结果表明,其精度可满足工程需要,且可将温度场分布适时进行可视化输出。与传统理论算法和有限元算法相比,该算法计算效率较高,可为同类问题提供参考。

Based on the concrete heat conduction equation and through the mathematical deduction,the one dimensional difference algorithm of interior and boundary is established and finite difference solution is used for the specific condition. Through the comparative analysis with the theoretical solution,the results show that its accuracy can meet engineering needs and the temperature field distribution can be timely visual output. Compared with theory method and finite element method,the high calculation efficiency of this algorithm can presents some references to similar projects.
