Computational Fluid Dynamics Co-processing for Unsteady Visualization

Abstract

With the ever growing computational power available on the largest parallel machines, the ability to generate CFD simulation data is outpacing the ability to analyze and visualize it. This is due to the large disparity between the computational facilities (up to hundreds of thousands of cores) and the typical personal computer or visualization cluster. This project's goal was to begin the analysis and visualization of these large data sets on the parallel computers they are being run on. This reduces the file size and further computation required to fully analyze the results. In this report we detail the steps that were taken in order to enable ParaView and VTK to perform this coprocessing of simulation data and visualization and analysis information. The main highlights are GUI tools to easily specify what is to be outputted during the simulation run and a coprocessing library that gets connected to the simulation code that does the actual processing of the desired results. In addition, we demonstrate good parallel performance for the coprocessing library on an IBM
