将基于快拍法的模型降阶方法应用于三维瞬态涡流问题的有限元分析。众所周知，简化模型的精度高度依赖于快照的数量。在本文中，我们介绍了一种新的方法，确定适当的快照自动的数量。结果表明，采用基于本方法的模型降阶，可以减少计算时间。
The model reduction based on the method of snapshots is applied to the finite element analysis of three-dimensional transient eddy current problems. It is known that accuracy of the reduced model highly depends on the number of snapshots. In this paper, we introduce a novel method which determines the adequate number of snapshots automatically. It is shown that the computational time can be reduced when using the model reduction based on the present method.
