Dynamic subscales and unconditional semi-discrete stability for non-residual VMS approximations of generalised Newtonian flows
G. R. Barrenechea, E. Castillo, R. Codina +2
We analyse a non-residual variational multiscale finite element formulation with dynamic subscales for incompressible generalised Newtonian Navier--Stokes flows. The apparent visco…
A numerical study to analyze the interplay of Weissenberg number and viscosity ratio in a log-strain tensorial model for viscoelastic fluids
Nehal Dash, Ramon Codina, Giulio G. Giusteri
We present a computational study aimed at exploring the different and independent roles of the Weissenberg number and of the ratio between the polymeric and solvent viscosity contr…
Finite element formulations for Maxwell's eigenvalue problem using continuous Lagrangian interpolations
Daniele Boffi, Ramon Codina, Önder Türk
We consider nodal-based Lagrangian interpolations for the finite element approximation of the Maxwell eigenvalue problem. The first approach introduced is a standard Galerkin metho…
Three-Field Fluid-Structure Interaction by Means of the Variational Multiscale Method
Alexis Tello, Ramon Codina
Three-field Fluid-Structure Interaction (FSI) formulations for fluid and solid are applied and compared to the standard two field-one field formulation for fluid and solid, respect…
A stabilized finite element method for the two-field and three-field Stokes eigenvalue problems
Önder Türk, Daniele Boffi, Ramon Codina
In this paper, the stabilized finite element approximation of the Stokes eigenvalue problems is considered for both the two-field (displacement-pressure) and the three-field (stres…
