Crouzeix--Raviart--Marini realisation of computable a priori $L^{2}$ -error bounds on anisotropic meshes

Hiroki Ishizaka

We consider conforming $\Pone$ and lowest-order Crouzeix--Raviart (CR) approximations of the Dirichlet Poisson problem in two and three dimensions. We obtain computable a priori $L…

Exact characterisation of maximum-angle conditions for spherical finite element meshes

Hiroki Ishizaka

Maximum-angle conditions are standard finite-element mesh hypotheses that permit anisotropic triangles excluded by minimum-angle or shape-regularity assumptions. For exact spherica…
