Semi-implicit numerical modeling of nonhydrostatic free-surface flows for environmental problems
Vincenzo Casulli,Paola Zanolli +1 more
TL;DR: A semi-implicit numerical model for the 3D Navier-Stokes equations on unstructured grids is derived and discussed in this article, where the governing differential equations are discretized by means of a finite difference-finite volume algorithm which is robust, very efficient, and applies to barotropic and baroclinic, hydrostatic and nonhydrostatic, and one-, two-, and three-dimensional flow problems.
Journal ArticleDOI
High resolution methods for multidimensional advection diffusion problems in free-surface hydrodynamics
Vincenzo Casulli,Paola Zanolli +1 more
TL;DR: In this paper, the numerical solution of advection-diffusion problems in free-surface hydrodynamic is analyzed and a new finite volume scheme for unstructured grid is derived.
Journal ArticleDOI
A Nested Newton-Type Algorithm for Finite Volume Methods Solving Richards' Equation in Mixed Form
Vincenzo Casulli,Paola Zanolli +1 more
TL;DR: In this article, a nested, Newton-type algorithm for discretizing the mixed form of the Richards' equation is proposed and analyzed, with a judicious choice of the initial guess, the quadratic convergence rate is obtained for any time step size.
Journal ArticleDOI
Iterative solutions of mildly nonlinear systems
Vincenzo Casulli,Paola Zanolli +1 more
TL;DR: In this paper two nested iterative methods for solving a mildly nonlinear system of the form V(@h)[email protected]=b are proposed and analysed and it is shown that the inner and the outer iterates are monotone, and converge to the exact solution for a wide class of mildly non linear systems of applied interest.
Journal ArticleDOI
Comparing analytical and numerical solution of nonlinear two and three‐dimensional hydrostatic flows
Vincenzo Casulli,Paola Zanolli +1 more
TL;DR: In this article, a semi-implicit finite difference-finite volume algorithm on unstructured grid is compared with the corresponding analytical solutions in both two and three space dimension.
