Resource Abstract

Standard finite volume based Computational Fluid Dynamics techniques have practical limitations resulting from time consuming pre-processing tasks. Typically, highly complex CAD models take several days of effort to clean the surface and up-to several days to generate a finite-volume based computational grid. This is especially true for highly complex applications such as water wading or full complexity gearboxes. Particle based techniques overcome this obstacle by skipping the meshing altogether. Furthermore, the computational tool used in this research, Smoothed Particle Hydrodynamics (SPH) based PreonLab, is not sensitive to the quality of the imported CAD data. Solver performance and post processing functionality contribute greatly to the engineering value of the simulation results, especially where full complexity needs to be considered for long physical times.
