## Abstract A higher‐order discontinuous enrichment method (DEM) with Lagrange multipliers is proposed for the efficient finite element solution on unstructured meshes of the advection–diffusion equation in the high Péclet number regime. Following the basic DEM methodology, the usual Galerkin polyn
