Since SPHERIC was born in 2005, the annual International Workshop has been the central event of our community, with exciting scientific talks and fruitful discussions. This is the place for all SPH researchers, students and practitioners to share knowledge and present their improvements, in a stimulating and friendly atmosphere. The present workshop in Paris will be of particular interest with the recent creation of the Grand Challenge Working Group, while SPHERIC is approaching its tenth anniversary. This workshop received 83 abstracts of good quality, and 60 of them were selected to appear in the present proceedings. This demonstrates the success of SPHERIC in fields ranging from sediment transport, solid mechanics and astrophysics to heterogeneous High Performance Computing and GPU programming. The present proceedings will allow the participants to enjoy a comprehensive description of the work exhibited by the speakers. For the 9 th SPHERIC International Workshop, it is with great pleasure that we welcome you all to the City of Paris. Thank you for your participation.

  • Conservative High Order Semi-Lagrangian Finite Difference WENO Methods for Advection in Incompressible Flow Jing-Mei Qiu1 and Ch
    Conservative high order semi-Lagrangian finite difference WENO methods for advection in incompressible flow Jing-Mei Qiu1 and Chi-Wang Shu 2 Abstract In this paper, we propose a semi-Lagrangian finite difference formulation for approximat- ing conservative form of advection equations with general variable coefficients. Compared with the traditional semi-Lagrangian finite difference schemes [4, 21], which approximate the advective form of the equation via direct characteristics tracing, the scheme proposed in this paper approximates the conservative form of the equation. This essential difference makes the proposed scheme naturally conservative for equations with general variable coef- ficients. The proposed conservative semi-Lagrangian finite difference framework is coupled with high order essentially non-oscillatory (ENO) or weighted ENO (WENO) reconstructions to achieve high order accuracy in smooth parts of the solution and to capture sharp inter- faces without introducing spurious oscillations. The scheme is extended to high dimensional problems by Strang splitting. The performance of the proposed schemes is demonstrated by linear advection, rigid body rotation and swirling deformation. As the information is propa- gating along characteristics, the proposed scheme does not have CFL time step restriction of the Eulerian method, allowing for a more efficient numerical realization for many application problems. Keywords: advection in incompressible flow; conservative scheme; semi-Lagrangian meth- ods; WENO reconstruction. 1Department of Mathematical and Computer Science, Colorado School of Mines, Golden, 80401.

  • High Order ADER Schemes and GLM Curl Cleaning for a First Order Hyperbolic Formulation of Compressible Flow with Surface Tension
    High order ADER schemes and GLM curl cleaning for a first order hyperbolic formulation of compressible flow with surface tension Simone Chiocchetti∗a, Ilya Peshkova, Sergey Gavrilyukb, Michael Dumbsera aLaboratory of Applied Mathematics, Department of Civil, Environmental and Mechanical Engineering, University of Trento, Via Mesiano 77, 38123 Trento, Italy bIUSTI UMR 7343-CNRS, D´epartement de M´ecanique, Aix-Marseille Universit´e,5 rue Enrico Fermi, 13453 Marseille, France Abstract In this work, we introduce two novel reformulations of the weakly hyperbolic model for two-phase flow with surface tension, recently forwarded by Schmidmayer et al. In the model, the tracking of phase boundaries is achieved by using a vector interface field, rather than a scalar tracer, so that the surface-force stress tensor can be expressed directly as an algebraic function of the state variables, without requiring the computation of gradients of the scalar tracer. An interesting and important feature of the model is that this interface field obeys a curl involution constraint, that is, the vector field is required to be curl-free at all times. The proposed modifications are intended to restore the strong hyperbolicity of the model, and are closely related to divergence-preserving numerical approaches developed in the field of numerical magnetohydrody- namics (MHD). The first strategy is based on the theory of Symmetric Hyperbolic and Thermodynamically Compatible (SHTC) systems forwarded by Godunov in the 60s and 70s and yields a modified system of governing equations which includes some symmetrisation terms, in analogy to the approach adopted later by Powell et al in the 90s for the ideal MHD equations.

  • Implementation and Validation of Semi-Implicit WENO Schemes Using Openfoam®
    computation Article Implementation and Validation of Semi-Implicit WENO Schemes Using OpenFOAM® Tobias Martin 1,* and Ivan Shevchuk 2 1 Department of Civil and Environmental Engineering, Norwegian University of Science and Technology, 7491 Trondheim, Norway 2 Chair of Modeling and Simulation, University of Rostock, 18059 Rostock, Germany; [email protected] * Correspondence: [email protected] Received: 3 December 2017; Accepted: 23 January 2018; Published: 24 January 2018 Abstract: In this article, the development of high-order semi-implicit interpolation schemes for convection terms on unstructured grids is presented. It is based on weighted essentially non-oscillatory (WENO) reconstructions which can be applied to the evaluation of any field in finite volumes using its known cell-averaged values. Here, the algorithm handles convex cells in arbitrary three-dimensional meshes. The implementation is parallelized using the Message Passing Interface. All schemes are embedded in the code structure of OpenFOAM® resulting in the access to a huge open-source community and the applicability to high-level programming. Several verification cases and applications of the scalar advection equation and the incompressible Navier-Stokes equations show the improved accuracy of the WENO approach due to a mapping of the stencil to a reference space without scaling effects. An efficiency analysis indicates an increased computational effort of high-order schemes in comparison to available high-resolution methods. However, the reconstruction time can be efficiently decreased when more processors are used. Keywords: CFD; high-order methods; WENO reconstruction; semi-implicit; unstructured grids 1. Introduction In recent years, open source Computational Fluid Dynamics (CFD) codes experienced an increased influence not only on ongoing science but also on the industry.

  • Essentially Non-Oscillatory and Weighted Essentially Non-Oscillatory Schemes
    Acta Numerica (2020), pp. 1–63 c Cambridge University Press, 2020 doi:10.1017/S09624929XXXXXX Printed in the United Kingdom Essentially non-oscillatory and weighted essentially non-oscillatory schemes Chi-Wang Shu Division of Applied Mathematics Brown University Providence, RI 02912, USA chi-wang [email protected] Essentially non-oscillatory (ENO) and weighted ENO (WENO) schemes were designed for solving hyperbolic and convection-diffusion equations with pos- sibly discontinuous solutions or solutions with sharp gradient regions. The main idea of ENO and WENO schemes is actually an approximation proce- dure, aimed at achieving arbitrarily high order accuracy in smooth regions and resolving shocks or other discontinuities sharply and in an essentially non-oscillatory fashion. Both finite volume and finite difference schemes have been designed using the ENO or WENO procedure, and these schemes are very popular in applications, most noticeably in computational fluid dynam- ics, but also in other areas of computational physics and engineering. Since the main idea of the ENO and WENO schemes is an approximation proce- dure not directly related to partial differential equations (PDEs), ENO and WENO schemes also have non-PDE applications. In this paper we will sur- vey the basic ideas behind ENO and WENO schemes, discuss their properties, and present examples of their applications to different types of PDEs as well as to non-PDE problems. 2 Chi-Wang Shu CONTENTS 1 Introduction 2 2 The ENO interpolation and reconstruction proce- dures 4 3 The WENO interpolation and reconstruction pro- cedures 14 4 ENO and WENO schemes for conservation laws 23 5 ENO and WENO schemes for Hamilton-Jacobi equations 31 6 ENO and WENO schemes for convection-diffusion equations 32 7 Time discretizations 33 8 Boundary conditions 34 9 Bound-preserving WENO schemes 34 10 Applications 35 11 Concluding remarks 45 References 45 1.
