The Cleanup Headache

摘要

CAD and CAE have existed in parallel for decades. Even if there were wrinkles in their data exchange before, by now the combined will of the software developers and users has solved the most severe issues, right? Wrong, according to H. Clark Briggs, Ph.D., from ATA Engineering Inc. ATA supplies design analysis and testing services to major manufacturers. Briggs, vice president of aerospace and defense business development, estimates his staff spends between 30% and 50% of the project time repairing their clients' geometry. Indrakanti Chakravarthy, Siemens PLM Software's director of simulation marketing for the Americas, has a higher estimate: "Up to 70% of an analyst's time is spent searching for data and preparing a model for analysis."
