Automated Preparation of Geometry for Computational Applications Final Report

Abstract

One of the major hurdles facing CFD practitioners is simplifying highly detailed models that were constructed for manufacturing. Features that are below the length scale of interest to a simulation, such as CFD, must be removed prior to meshing. Importing neutral files such as IGES can be particularly time consuming because sometimes you get many disconnected sheets. The overall objective of this effort is to reduce the time required to prepare models for CFD from in some cases weeks to under a day. The reduction in model preparation time comes from the new ability to automatically remove features from a model and assist the analyst in resolving geometry import problems.
