We prove convergence of the Maxwell eigenvalue problem using quadratic or higher Lagrange finite elements on Worsey–Farin splits in three dimensions. To do this, we construct two Fortin-like operators to prove uniform convergence of the corresponding source problem. We present numerical experiments to illustrate the theoretical results.

3D 麦克斯韦特征值问题的拉格朗日有限元方法的收敛性

我们使用二维或更高的拉格朗日有限元在三维 Worsey-Farin 分裂上证明了麦克斯韦特征值问题的收敛性。为此,我们构造了两个类 Fortin 算子来证明相应源问题的一致收敛。我们提出数值实验来说明理论结果。
