In linear thermoelasticity models, the temperature T and the displacement components u 1 , u 2 exhibit large qualitative differences: While T typically is very smooth everywhere in the domain, the displacements u 1 , u 2 have singular gradients (stresses) at re-entrant corners and edges. The mesh must be extremely fine in these areas so that stress(More)

We present a novel compression algorithm for 2D scientific data and images based on exponentially-convergent adaptive higher-order finite element methods (FEM). So far, FEM has been used mainly for the solution of partial differential equations (PDE), but we show that it can be applied to data and image compression easily. The adaptive compression algorithm(More)
