Error estimates for Q1 isoparametric elements satisfying a weak angle condition
We prove optimal order error estimates in the H1 norm for the Q1 isoparametric interpolation on convex quadrilateral elements under rather weak hypotheses, improving previously known results. Choose one diagonal and divide the element into two triangles. We show that, if the chosen diagonal is the l...
