研究了广义IMBq方程的非协调有限元方法,在不需要传统的Ritz投影的情况下,给出了其收敛性分析,得到了与协调元情形相同的最优误差估计.
A kind of nonconforming finite element approximation to Generalized IMBq Equation is discussed with semidiscrete scheme. The convergence analysis is presented, and the same optimal error estimates are derived as conforming element methods without Ritz projection.
