Adaptive Solution of a Singularly-Perturbed Convection-Diffusion Problem Using a Stabilized Mixed Finite Element Method
Gonzalez, M.; Strugaru, M.
(2019-01-05)
We explore the applicability of a new adaptive stabilized dual-mixedfinite element method to a singularly-perturbed convection-diffusion equation withmixed boundary conditions. We establish the rate of convergence when the ...

Necking in 2D incompressible polyconvex materials: theoretical framework and numerical simulations
Mora-Corral, C.; Strugaru, M. (2017-06-15)
We show examples of 2D incompressible isotropic homogeneous hyperelastic materials with a poly-convex stored-energy function that present necking. The construction of the stored-energy function of amaterial satisfying all ...

A Simulation Method for the Computation of the E
Omella, A. J.; Alvarez-Aramberri, J.; Strugaru, M.; Darrigrand, V.; Pardo, D.; Gonzalez, H.; Santos, C. (2021-03)
We propose a set of numerical methods for the computation of the frequency-dependent eff ective primary wave velocity of heterogeneous rocks. We assume the rocks' internal microstructure is given by micro-computed tomography ...

Stabilization and a posteriori error analysis of a mixed FEM for convection–diffusion problems with mixed boundary conditions
Gonzalez, M.; Strugaru, M. (2020-06-02)
We introduce a new augmented dual-mixed finite element method for the linear convection-diffusion equation with mixed boundary conditions. The approach is based on adding suitable residual type terms to a dual-mixed ...
