Block-structured, equal-workload, multi-grid-nesting interface for the Boussinesq wave model FUNWAVE-TVD (Total Variation Diminishing) [PDF]

open access: yesGeoscientific Model Development, 2022
We describe the development of a block-structured, equal-CPU-load (central processing unit), multi-grid-nesting interface for the Boussinesq wave model FUNWAVE-TVD (Fully Nonlinear Boussinesq Wave Model with Total Variation Diminishing Solver).

A total variation diminishing interpolation operator and applications [PDF]

open access: yesMathematics of Computation, 2015
We construct an interpolation operator that does not increase the total variation and is defined on continuous first degree finite elements over Cartesian meshes for any dimension d d

Total variation diminishing Runge-Kutta schemes [PDF]

open access: yesMathematics of Computation, 1998
In this paper we further explore a class of high order TVD (total variation diminishing) Runge-Kutta time discretization initialized in a paper by Shu and Osher, suitable for solving hyperbolic conservation laws with stable spatial discretizations. We illustrate with numerical examples that non-TVD but linearly stable Runge-Kutta time discretization ...

Study of total variation diminishing (TVD) slope limiters in dam-break flow simulation

open access: yesWater Science and Engineering, 2018
A two-dimensional (2D) dam-break flow numerical model was developed based on the finite-volume total variation diminishing (TVD) and monotone upstream-centered scheme for conservation laws (MUSCL)-Hancock scheme, which has second-order accuracy in both ...

Change in medical practice over time? A register based study of regional trends in hysterectomy in Finland in 2001–2018

open access: yesBMC Women's Health, 2021
Background A persistent research finding in Finland and elsewhere has been variation in medical practices both between and within countries. Variation seems to exist especially if medical decision making involves discretion and the best treatment cannot ...

A total variation diminishing scheme for two-dimensional shallow water equations on mixed unstructured grids

open access: yesShui kexue jinzhan, 2013
Unstructured grids are usually adopted in the solution of complex boundary flows.In this study,a depth-averaged two-dimensional(2-D) flow model is developed for mixed unstructured grids.The model uses both triangular cells and quadrilaterals,which ...

Adaptive symmetric flux limiters with long computation times for hyperbolic conservation laws

open access: yesResults in Applied Mathematics, 2023
The construction of the limiter is a critical factor in the traditional Total Variation Diminishing (TVD) scheme. Among the classical limiters, superbee has the lowest numerical dissipation, but it can lead to over-compression in smooth regions and ...
