Abstract

We describe a spectral element solution strategy for simulation of weakly turbulent vascular flows. Novel approaches for treatment of outflow boundary conditions and flow division are presented. We demonstrate that several million gridpoints are required to obtain converged rms statistics when uniform refinement is used and discuss possible approaches to cost reduction.
