OVERVIEW ATA Engineering, Inc., (ATA) in support of Huntington Ingalls Industries (HII), was funded by the National Shipbuilding Research Program to automate the creation of finite element models in Femap. Based on requirements defined by HII, ATA created a Femap toolbox to reduce the amount of time necessary to create analysis models from CAD geometry. The tools aimed to automate manual tasks within Femap and provide shortcuts for tedious procedures. As the most time-consuming part of creating an analysis model is often the creation of meshable geometry, a process that can include simplification of geometry and creation of mid-surfaces, the toolbox contained several programs for creating or editing mid-surface models—allowing up to a 60% decrease in model creation time—as well as
