The Galerkin (=0) solution with either consistent (=1)or lumped mass(=0)approximation is well-resolved as predicted from then ite element dispersion results,i.e. e p 1.

Galerkin Method

Galerkin Method  Engineering problems: differential equations with boundary conditions. Generally denoted as: D(U)=0; B(U)=0  Our task: to find the function U which satisfies the given differential equations and boundary conditions.  Reality: difficult, even impossible to solve the ...
