涡流检测仿真中的多物体问题研究

Research of the Multi-Object in Eddy Current Testing Simulation

传统涡流仿真模型仅包含单一求解区域,将所有物体囊括在内。随着近代工业科技的飞速发展,被检物体日趋复杂,从而使得传统涡流仿真模型的计算效率降低。将单一求解区域划分为数个子区域,可以有效克服网格模型复杂的问题。简要介绍分解区域在电磁及涡流检测中的应用。

Tradition eddy current testing models have only one solution domain, including all objects. With the high speed develop of Industrial Sciences and Technology, the detected objects become complex, so the convention models are inefficiency. Decomposing the whole domain into some sub-domain is a way to overcome the problem of complex meshes. In this article, author will introduce the domain decomposition method using in electromagnetic problems and application in eddy current testing.
