摘要
为了解决电磁感应加热仿真中因目标体积太大或者太小、时间长而难以仿真的问题,介绍了一种对空间和时间进行多尺度变换的快速计算方法。通过有限元方法仿真计算和对比验证,尺度变换后所得结果与变换之前吻合良好,能够减少大物体建模仿真的运算数据量。当时间尺度分别缩小10倍和100倍时,计算所需的时间分别减少了81.7%和91.8%。
This paper presents a multi-scale transform based fast algorithm to realize the electromagnetic induction heating simulation for time consuming model with very large or small dimension Several numerical examples are computed using the proposed algorithm by Finite Element Method(FEM), and good agreements are obtained between the results with and without transform. The data amount required in computing are reduced in big models. The CPU time can be reduced by 81.7% and 91.8% respectively when time scales are 1/10 and 1/100 of that of original model.
