چکیده

We introduce and analyze a discontinuous Galerkin method for the numerical modeling of equations Multiple-Network Poroelastic Theory (MPET) in dynamic formulation. The MPET model can comprehensively describe functional changes brain considering multiple scales fluids. Concerning spatial discretization, we employ high-order on polygonal polyhedral grids derive stability priori error estimates. temporal discretization is based coupling between Newmark [Formula: see text]-method momentum equation pressure equations. After presentation some verification tests, perform convergence analysis using an agglomerated mesh geometry slice. Finally, present simulation three-dimensional patient-specific reconstructed from magnetic resonance images. presented this paper be regarded as preliminary attempt to perfusion brain.

High-Order Discontinuous Galerkin Methods for CFD

In recent years it has become clear that the current computational methods for scientific and engineering phenomena are inadequate for many challenging problems. Examples of these problems are wave propagation, turbulent fluid flow, as well as problems involving nonlinear interactions and multiple scales. This has resulted in a significant interest in so-called high-order accurate methods, whic...

High-Order Discontinuous Galerkin Methods by GPU Metaprogramming

Discontinuous Galerkin (DG) methods for the numerical solution of partial differential equations have enjoyed considerable success because they are both flexible and robust: They allow arbitrary unstructured geometries and easy control of accuracy without compromising simulation stability. In a recent publication, we have shown that DG methods also adapt readily to execution on modern, massivel...

High-Order Discontinuous Galerkin Methods for Turbulent High-lift Flows

In this work a robust discontinuous Galerkin (DG) solver for turbulent high-lift aerodynamic flows using the turbulence model of Spalart and Allmaras (SA) is developed. The application of DG discretizations to turbulent RANS flows is one of the most pressing issues facing high-order methods on unstructured grids. The issue is the result of non-smooth behavior of the turbulence model equation, w...

Bridging the Hybrid High-Order and Hybridizable Discontinuous Galerkin Methods

We build a bridge between the hybrid high-order (HHO) and the hybridizable discontinuous Galerkin (HDG) methods in the setting of a model diffusion problem. First, we briefly recall the construction of HHO methods and derive some new variants. Then, by casting the HHO method in mixed form, we identify the numerical flux so that the HHO method can be compared to HDG methods. In turn, the incorpo...

High-order Discontinuous Galerkin Methods: Simulation of Coil Flows

We have developed spectral methods in the discontinous Galerkin framework appropriate for simulations of high-speed flows in complex-geometry domains. In this paper we present details of the stability of the method and demonstrate the importance of over-integration for strongly nonlinear problems. We then present results from the application of the method to stability studies of supersonic and ...
