An optimization approach for flow simulations in poro-fractured media with complex geometries
Stefano Berrone, Alessandro D'Auria, Stefano Scialo'
A new discretization approach is presented for the simulation of flow in complex poro-fractured media described by means of the Discrete Fracture and Matrix Model. The method is ba…
Anisotropic a posteriori error estimate for the Virtual Element Method
Paola Francesca Antonietti, Stefano Berrone, Andrea Borio +3
We derive an anisotropic a posteriori error estimate for the adaptive conforming Virtual Element approximation of a paradigmatic two-dimensional elliptic problem. In particular, we…
A Three-Field based optimization formulation for flow simulations in networks of fractures on non conforming meshes
Stefano Berrone, Denise Grappein, Sandra Pieraccini +1
A new numerical scheme is proposed for flow computation in complex discrete fracture networks. The method is based on a three-field formulation of the Darcy law for the description…
Refinement strategies for polygonal meshes applied to adaptive VEM discretization
Stefano Berrone, Andrea Borio, Alessandro D'Auria
In the discretization of differential problems on complex geometrical domains, discretization methods based on polygonal and polyhedral elements are powerful tools. Adaptive mesh r…
