This presentation discusses best practices for expediting the midsurface geometry process. Specifically, a new semi-automatic or incremental method for creating midsurface geometry will be presented. The concepts mentioned in the presentation will be demonstrated on an injection molded plastic component. The same component required 10 hours to complete with existing pre/post processors, but once the incremental midsurface method is adopted, the process required 1 hour. The MSC Apex incremental midsurface method will be used throughout the live demonstration.
Constructing midsurface geometry and meshes for Finite Element Analysis (FEA) is a process often requiring hours to days to complete. Existing midsurface extraction methods in pre/post processors, while automated, often produce very incomplete midsurface geometry. As a consequence, significantly more time is required before midsurface geometry is completed and meshed.
