Describes a new finite element scheme for the large-scale analysis of compressible and incompressible viscous flows. The scheme is based on a combined compressible- incompressible Galerkin least-squares (GLS) space-time variational formulation. Three- dimensional unstructured meshes are employed, with piecewise-constant temporal interpolation, local time-stepping for steady flows, and linear continuous spatial interpolation in all the variables. The scheme incorporates automatic adaptive mesh refinement, with a choice of various error indicators. It is implemented on a distributed-memory parallel computer, and includes an automatic load-balancing procedure. Demonstrates the ability to solve both compressible and incompressible viscous flow problems using the parallel adaptive framework via numerical examples. These include Mach 3 flow over a flat plate, and a divergence-free buoyancy-driven flow in a cavity. The latter is a model for the steady melt flow in a Czochralski crystal growth process.
