The reason to use MSC Apex is the raw time savings you will achieve over your current preprocessor. MSC Apex gives you powerful tools that are both easy to use and highly intuitive. The result is arriving at a nearly analysis-ready model in far less time. The time saved can be applied towards getting a head-start on the next project. In one example, TLG Aerospace, a services group specialising in certifying aircraft, reduced the time to create the midsurface geometry and mesh of an airframe from 25.2 hours to six hours.
