The arbitrary order mimetic finite difference method for a diffusion equation with a non-symmetric diffusion tensor
10.1016/j.jcp.2017.07.019 2017-07-18 We present the arbitrary order mimetic finite difference (MFD) discretization for the diffusion equation with non-symmetric tensorial diffusion coefficient in a mixed formulation on general polygonal meshes. The diffusion tensor is assumed to be positive defi... |

Effects of High-Frequency Damping on Iterative Convergence of Implicit Viscous Solver
10.1016/j.jcp.2017.07.021 2017-07-18 This paper discusses effects of high-frequency damping on iterative convergence of an implicit defect-correction solver for viscous problems. The study targets a finite-volume discretization with a one parameter family of damped viscous schemes. The parameter... |

Modified GMDH-NN algorithm and its application for global sensitivity analysis ☆
10.1016/j.jcp.2017.07.027 2017-07-18 Global sensitivity analysis (GSA) is a very useful tool to evaluate the influence of input variables in the whole distribution range. Sobol' method is the most commonly used among variance-based methods, which are efficient and popular GSA techniques. High di... |

Stellar surface as low-rank modification in iterative methods for binary neutron stars
10.1016/j.jcp.2017.07.026 2017-07-18 We present a new multidomain spectral method for the treatment of non-spherical stellar surfaces in iterative methods for binary neutron stars. A stellar surface changes throughout the course of an iterative solution, potentially stalling the convergence. Our... |

A continuum mechanics-based musculo-mechanical model for esophageal transport
10.1016/j.jcp.2017.07.025 2017-07-18 In this work, we extend our previous esophageal transport model using an immersed boundary (IB) method with discrete fiber-based structural model, to one using a continuum mechanics-based model that is approximated based on finite elements (IB-FE). To deal wi... |

A new multi-domain method based on an analytical control surface for linear and second-order mean drift wave loads on floating bodies
10.1016/j.jcp.2017.07.014 2017-07-18 A novel multi-domain method based on an analytical control surface is proposed by combining the use of free-surface Green function and Rankine source function. A cylindrical control surface is introduced to subdivide the fluid domain into external and interna... |

High order ADER schemes for a unified first order hyperbolic formulation of Newtonian continuum mechanics coupled with electro-dynamics
10.1016/j.jcp.2017.07.020 2017-07-17 In this paper, we propose a new unified first order hyperbolic model of Newtonian continuum mechanics coupled with electro-dynamics. The model is able to describe the behavior of moving elasto-plastic dielectric solids as well as viscous and inviscid fluids i... |

SPH with dynamical smoothing length adjustment based on the local flow kinematics
10.1016/j.jcp.2017.07.023 2017-07-17 Due to the Lagrangian nature of Smoothed Particle Hydrodynamics (SPH), the adaptive resolution remains a challenging task. In this work we first analyse the influence of the simulation parameters and the smoothing length on the solution accuracy, in particula... |
