Computations of Unsteady Viscous Compressible Flows Using Adaptive Mesh Refinement in Curvilinear Body-Fitted Grid Systems

A methodology for accurate ana efficient simulation of unsteady, compressible flows is presented. The cornerstones of the methodology are a. special discretization of the N avier-Stokes equa.tions on structured bodyfitted grid systems and an efficient solution-adaptive mesh refinement technique for structured grids. The discretization employs an explicit multidimensional upwind scheme for the i...

AGRIF: Adaptive grid refinement in Fortran

Adaptive grid refinement in Fortran (AGRIF) is a Fortran90 package for the integration of adaptive mesh refinement (AMR) features within existing finite difference codes. The package first provides model-independent Fortran90 procedures containing the different operations in an AMR process: time integration of grid hierarchy, clustering, interpolations, updates, etc. The package then creates th...

Automatic Adaptive Grid Refinement for the Euler Equations

We present a method of adaptive grid refinement for the solution of the steady Euler equations for transonic flow. Our algorithm automatically decides where the coarse grid accuracy Is insufficient, and creates locally uniform refined grids in these regions. This typically occurs at the leading and trailing edges. The solution is then integrated to steady state using the same integrator (FLO52)...

Parallel Computing for Reacting Flows Using Adaptive Grid Refinement

The paper reports on the parallelisation of the computational code for modelling turbulent combustion in large industrial 3D glass melting furnaces. Domain decomposition is used to perform the parallelisation. Performance optimisation is examined, to both speed up the code as well as to improve convergence. Local grid refinement is discussed using several different refinement criteria. The nume...
