We consider the Galerkin finite element method for partial differential equations in two dimensions, where the finite-dimensional space used consists of piecewise (isoparametric) polynomials enriched with bubble functions. Writing L for the differential operator, we show that for elliptic convection
Errors associated with the finite element solution to the transient heat equation are examined. These errors arise from the spatial and temporal discretizations chosen and are influenced by the shape of the thermal profile and the properties of the conducting medium. Since these errors alter the rat
