Sigma Engineering GmbH in Aachen, Germany, presented its new Sigmasoft Version 5.0, the latest release of its process simulation software, at the DKT German rubber conference in Nuremberg, Germany, in July.
Features include a completely reengineered solver technology and a new meshing concept, which has dramatically cut calculation times on the three-dimensional simulation.
“With Sigmasoft Version 5.0, we have achieved a major breakthrough in injection molding simulation,” said Marco Thornagel, executive manager. “Some years ago, users had to wait sometimes days to get the results of a simulation. It was not viable to use simulation to support everyday production activities, or to quickly optimize products. Now, however, simulation can be part of the daily production tools used in the mold shop or in the production floor, to deliver reliable and profitable answers both to design new products and to optimize existing molds.”
The new meshing technique uses “unstructured meshes,” which can automatically mesh finer regions of the mold, such as part boundaries, thin walls or complex runner systems. It also can save mesh elements in areas where fewer interactions take place, such as mold boundaries.
Through a process called parallelization, the new solver makes it possible to exploit the full potential of multi-core technology in computers. That reduces computational time and allows users to simulate more-complex injection molding processes.
The company's U.S. operation, Sigma Plastic Services Inc., is in Schaumburg, Ill.
