摘要：

An L2 Galerkin approximation is obtained by the use of specially chosen spaces of trial and test functions. The method combines the features of the orthogonal collocation and Galerkin finite element methods. This new algorithm can be more efficient by orders of magnitude than conventional discontinuous Galerkin finite element procedures in solving non‐linear problems which require frequent reformulation of the coefficient matrices and right‐hand‐side vectors.
