摘要
通过矩形域上的B样条插值函数逼近定义于该域内任意子域上的待求函数,并用广义变分原理处理第一类边界条件,本文建立了适合于一般二维区域的B样条有限元法。实例计算表明了该方法的优点和实用价值。
A B-spline finite etement method for solving general 2-D electromagnetic field problems is established. The B-spline bases for a general field region are constructed using the Bspline interpolation functions defined on a rectangle which contains the region. The Dirichlet boundary condition is dealt with by means of the generalized variational principle. Two numerical examples are given that show the characteristics and practical value of the method.
