A posteriori error estimator for elliptic interface problems in the fictitious formulation
Najwa Alshehri, Daniele Boffi, Lucia Gastaldi
A posteriori error estimator is derived for an elliptic interface problem in the fictitious domain formulation with distributed Lagrange multiplier considering a discontinuous Lagr…
Quadrature error estimates on non-matching grids in a fictitious domain framework for fluid-structure interaction problems
Daniele Boffi, Fabio Credali, Lucia Gastaldi
We consider a fictitious domain formulation for fluid-structure interaction problems based on a distributed Lagrange multiplier to couple the fluid and solid behaviors. How to deal…
A nodal ghost method based on variational formulation and regular square grid for elliptic problems on arbitrary domains in two space dimensions
Clarissa Astuto, Daniele Boffi, Giovanni Russo +1
This paper focuses on the numerical solution of elliptic partial differential equations (PDEs) with Dirichlet and mixed boundary conditions, specifically addressing the challenges…
On the stabilization of a virtual element method for an acoustic vibration problem
Linda Alzaben, Daniele Boffi, Andreas Dedner +1
In this paper we introduce an abstract setting for the convergence analysis of the virtual element approximation of an acoustic vibration problem. We discuss the effect of the stab…
Adaptive Mixed FEM for the Stokes eigenvalue problem
Daniele Boffi, Arbaz Khan
In this paper we discuss the optimal convergence of a standard adaptive scheme based on mixed finite element approximation to the solution of the eigenvalue problem associated with…
