The superconvergent patch recovery (SPR) with bilinear interpolation functions usually gives good values of recovered stresses in an element patch. However, when 4-node quadrilateral elements meeting at a node are rigidly rotated with the essential and natural boundary conditions unchanged, the reco

✦ Synopsis
In this work, we investigate numerically the possibility of joining the superconvergent patch recovery technique and discontinuous ÿnite element formulations so that adaptive methods involving independent local mesh reÿnement processes and possibly di erent polynomial degrees in neighbouring elements can be constructed.

A new point of view based on a "nite element formulation for solving Maxwell's equations in the time domain is presented to deal with grid re"nements in FDTD. The formulation allows the coupling of non-conforming structured or unstructured meshes. As a special case, it can advantageously derive stab
The performance of three different stress recovery procedures, namely, the superconvergent patch recovery technique (SPR), the recovery by equilibrium in patches (REP) and a combined method known as the LP procedure is reviewed. Different order of polynomials and various patch formation strategies h
