ABSTRACT
This paper presents two global convergence strategies for a spectral-element, space-time discretisation of the Navier–Stokes equations. The first employs a hierarchical temporal mesh subdivision and polynomial order reduction to approximate the high-order solution. The second generalises Pseudo-Transient Continuation for steady problems to a space-time system.
