Inf-sup stabilized Scott-Vogelius pairs on general simplicial grids for Navier-Stokes equations
Naveed Ahmed, Volker John, Xu Li +1
This paper considers the discretization of the time-dependent Navier-Stokes equations with the family of inf-sup stabilized Scott-Vogelius pairs recently introduced in [John/Li/Mer…
An Assessment of Solvers for Algebraically Stabilized Discretizations of Convection-Diffusion-Reaction Equations
Abhinav Jha, Ondřej Pártl, Naveed Ahmed +1
We consider flux-corrected finite element discretizations of 3D convection-dominated transport problems and assess the computational efficiency of algorithms based on such approxim…
Analysis of Flux Corrected Transport Schemes for Evolutionary Convection-Diffusion-Reaction Equations
Abhinav Jha, Naveed Ahmed
We report in this paper the analysis for the linear and nonlinear version of the flux corrected transport (FEM-FCT) scheme in combination with the backward Euler time-stepping sche…
A pressure-robust discretization of Oseen's equation using stabilization in the vorticity equation
Naveed Ahmed, Gabriel R. Barrenechea, Erik Burman +3
Discretization of Navier-Stokes' equations using pressure-robust finite element methods is considered for the high Reynolds number regime. To counter oscillations due to dominating…
Higher-order discontinuous Galerkin time discretizations the evolutionary Navier--Stokes equations
Naveed Ahmed, Gunar Matthies
Discontinuous Galerkin methods of higher order are applied as temporal discretizations for the transient Navier--Stokes equations. The spatial discretization based on inf-sup stabl…
Numerical comparisons of finite element stabilized methods for high Reynolds numbers vortex dynamics simulations
Naveed Ahmed, Samuele Rubino
In this paper, we consider up-to-date and classical Finite Element (FE) stabilized methods for time-dependent incompressible flows. All studied methods belong to the Variational Mu…
ParMooN - a modernized program package based on mapped finite elements
Ulrich Wilbrandt, Clemens Bartsch, Naveed Ahmed +11
{\sc ParMooN} is a program package for the numerical solution of elliptic and parabolic partial differential equations. It inherits the distinct features of its predecessor {\sc Mo…
