In this paper, we present an enhanced framework for the synthetic asphalt concrete (AC) microstructure generation for the numerical analysis purposes. It is based on the Voronoi tessellation concept with some necessary extensions that allow for the r

Application of a Discontinuous Petrov-Galerkin (DPG) method for simulation of compressible viscous flows in three dimensions is presented. The approach enables construction of stable schemes for problems with a small perturbation parameter. The main

We present the application of the Discontinuous Petrov–Galerkin (DPG) methodology for the mixed Multiscale Finite Element Method (MsFEM). The MsFEM upscaling technique relies on incorporating fine-scale features through special, in a sense optimize

The Discontinuous Petrov-Galerkin (DPG) method allows one to construct stable finite element schemes for some classes of singularily perturbed problems like, for instance, convection-dominated diffusion. The central ingredient of the method is a spec

The mixed finite element method uses an approximation of at least two fields (e.g. displacements and stresses). Even though it is difficult to construct stable approximation for such formulations, the mixed methods provide much better convergence of
