An incompressible flow simulation environment for parallel and distributed computers
An incompressible flow simulation environment for parallel and distributed computers
In recent years novel computer architectures have been developed which utilise large numbers of processors to deliver substantial performance gains over single processor systems. Despite these hardware advances, software for system support and application programming remains an unresolved issue. Computational fluid dynamics were one of the first numerical disciplines to embrace these new architectures. However, early applications exposed the user to the underlying architecture.
This thesis considers the implementation of an integrated environment for 2-D Incompressible flows. The environment consists of an Incompressible Navier Stokes solver and several tools whose aims are to assist the user in the definition of problem geometry, execution and visualisation of computed flows. The Navier Stokes equations are discretised in space and time using the Spectral Element Methods and a first order fractional time splitting scheme respectively. To enable the concentration of grid points in areas of interest we have also implemented the Mortar Element Method. Using a modular design the developed solver can handle with ease new boundary conditions and complex geometries. In addition it has been ported to a range of parallel computers including T800 Transputer arrays, Intel iPSC/860, Meiko CS2,IBM SP2, SG Power Challenge and a cluster of SG Indy workstations.

Abstract
In recent years novel computer architectures have been developed which utilise large numbers of processors to deliver substantial performance gains over single processor systems. Despite these hardware advances, software for system support and application programming remains an unresolved issue. Computational fluid dynamics were one of the first numerical disciplines to embrace these new architectures. However, early applications exposed the user to the underlying architecture.
This thesis considers the implementation of an integrated environment for 2-D Incompressible flows. The environment consists of an Incompressible Navier Stokes solver and several tools whose aims are to assist the user in the definition of problem geometry, execution and visualisation of computed flows. The Navier Stokes equations are discretised in space and time using the Spectral Element Methods and a first order fractional time splitting scheme respectively. To enable the concentration of grid points in areas of interest we have also implemented the Mortar Element Method. Using a modular design the developed solver can handle with ease new boundary conditions and complex geometries. In addition it has been ported to a range of parallel computers including T800 Transputer arrays, Intel iPSC/860, Meiko CS2,IBM SP2, SG Power Challenge and a cluster of SG Indy workstations.
