Parallel Simulation Algorithms for Grid-Based Analog Signal Processors

Parallel Simulation Algorithms for Grid - Based Analog Signal

In this paper, specialized algorithms for circuit-level simulation of grid-based analog signal processing arrays on a massively parallel processor are described and implementation results presented. In our approach, the trapezoidal rule is used to discretize the diierential equations that describe the analog array behavior, Newton's method is used to solve the nonlinear equations generated at e...

Mixed Large-Eddy Simulation Model for Turbulent Flows across Tube Bundles Using Parallel Coupled Multiblock NS Solver

In this study, turbulent flow around a tube bundle in non-orthogonal grid is simulated using the Large Eddy Simulation (LES) technique and parallelization of fully coupled Navier – Stokes (NS) equations. To model the small eddies, the Smagorinsky and a mixed model was used. This model represents the effect of dissipation and the grid-scale and subgrid-scale interactions. The fully coupled NS eq...
