A Variant of the C0 Interior Penalty Method for the Biharmonic Equation
Dienstag, 21.1.14, 14:15-15:15, Raum 226, Hermann-Herder-Str. 10
We consider a symmetric interior penalty method for the Biharmonic Problem which weakly over-penalizes the jumps of the normal derivatives across element boundaries and which can handle meshes with hanging nodes. The notion of meshes generated by independent refinements will be introduced and a general analysis of piecewise H2-functions associated with those meshes will be presented. We derive a priori error estimates in the energy norm and the L2-norm for a class of meshes generated by independent refinements and demonstrate the performance by numerical results.
