Abstract
I will present some recent finite element methods that have attractive mimetic properties for incompressible flows. A particular feature is "pressure robustness" for mixed methods for incompressible flows, where a priori error estimates for the velocity are independent of the pressure approximation. With a view to extreme scale computing, the generalisation of the methods to high-order geometries and various cell types will be discussed, and provably optimal preconditioning strategies for the methods presented.
