Output-Based Space-Time Mesh Adaptation for Unsteady Aerodynamics
An adjoint-based output error estimation algorithm is presented for unsteady problems discretized on static meshes with a space-time discontinuous Galerkin finite element method. An approximate factorization technique is used to solve both the forward and the discrete adjoint problems. A space-time anisotropy measure based on projection of the adjoint solution is used to attribute the error to ...
متن کاملAdjoint Based Anisotropic Mesh Adaptation for the CPR Method
Adjoint-based adaptive methods have the capability of dynamically distributing computing power to areas which are important for predicting an engineering output such as lift or drag. In this paper, we apply an anisotropic h-adaptation method for simplex meshes using the correction procedure via reconstruction(CPR) method with the target of minimizing the output error. An adjoint-based error est...
متن کاملOutput-based mesh adaptation for high order Navier-Stokes simulations on deformable domains
We present an output-based mesh adaptation strategy for Navier-Stokes simulations on deforming domains. The equations are solved with an arbitrary Lagrangian-Eulerian (ALE) approach, using a discontinuous Galerkin finiteelement discretization in both space and time. Discrete unsteady adjoint solutions, derived for both the state and the geometric conservation law, provide output error estimates...
متن کاملA 3D Goal-Oriented Anisotropic Mesh Adaptation Applied to Inviscid Flows in Aeronautics
This paper studies the coupling between anisotropic mesh adaptation and goal-oriented error estimate. The former is very well suited to the control of the interpolation error. It is generally interpreted as a local geometric error estimate. On the contrary, the latter is preferred when studying approximation errors for PDEs. It generally involves non local error contributions. Consequently, a f...
متن کاملPhD Position at Inria Saclay-Ile de France Title: Anisotropic Mesh Adaptation for RANS Simulations with Moving Geometries in Aeronautics
Subject: The aim of mesh adaptation is to generate automatically the best mesh to perform a specific numerical simulation [1]. It results in a powerful methodology that reduces significantly the size of the mesh required to reach the desired accuracy. Thus, it impacts favorably the simulation CPU time and memory requirement. Moreover, as the generated adapted mesh is in agreement with the physi...
