L^2-Error estimates for H(div)-conforming schemes applied to a linearised model of inviscid incompressible flow
share
In this note an error estimate in the $L^2$-norm of order $O(h^{k+\frac12})$ is proven for a finite element method for a linearised model of inviscid incompressible flow. We also prove error estimates of the same order for the pressure error in the $L^2$-norm.
