摘要: 用现行的一次有限元解轴对称磁场时,在单元中心得到的磁感应强度会随径向格点作非物理的激烈振荡。我们分析了产生这种振荡的原因及其特性,并与网络的不均匀性引起的振荡作了比较。

Abstract: The oscillating solutions of the magnetic fields may arise on an axisymmetric model by using first order finite elements.In addtion,they may also occur for nonuniform grids.The paper analyses the cause of forming oscillating solutions and the behaviour of oscillating solutions.The methods of cancelling the oscillation are suggested.

Key words: First order finite element, Axisymmetric model, Magnetic field
