Locating critical solutions in numerical relativity using automatic differentiation
David Bambague, Miguel Bezares, Katy Clough +1
Numerical relativity is a term used to describe the solution of the full non-linear Einstein Equations as an initial value problem using numerical methods. Individual simulations a…
Generalised Quasilinear Approximation of the Interaction of Convection and Mean Flows in a Thermal Annulus
S. M. Tobias, J. Oishi, J. B. Marston
In this paper we examine the interaction of convection, rotation and mean flows in a thermal annulus. In this system mean flows are driven by correlations induced by rotation leadi…
Dimensional Reduction of Direct Statistical Simulation
Altan Allawala, S. M. Tobias, J. B. Marston
Direct Statistical Simulation (DSS) solves the equations of motion for the statistics of turbulent flows in place of the traditional route of accumulating statistics by Direct Nume…
Three-Dimensional Rotating Couette Flow Via The Generalised Quasilinear Approximation
Steven Tobias, Brad Marston
We examine the effectiveness of the Generalised Quasilinear (GQL) Approximation introduced by Marston et al (2016). This approximation splits the variables into large and small sca…
Direct Statistical Simulation of a Jet
J. B. Marston, Wanming Qi, S. M. Tobias
We review progress that has been made in utilizing one form of Direct Statistical Simulation (DSS) to describe geophysical and astrophysical flows that are anisotropic and inhomoge…
Direct Statistical Simulation of Out-of-Equilibrium Jets
Steven Tobias, Brad Marston
We present a Direct Statistical Simulation (DSS) of jet formation on a β-plane, solving for the statistics of a fluid flow via an expansion in cumulants. Here we compare an expansi…
Astrophysical Fluid Dynamics via Direct Statistical Simulation
S. M. Tobias, K. Dagon, J. B. Marston
In this paper we introduce the concept of Direct Statistical Simulation (DSS) for astrophysical flows. This technique may be appropriate for problems in astrophysical fluids where…
