GT-POWER Advanced Training: Use of GEM-3D – Germany

GEM 3D is a CAD-based tool that is designed to assist users in the modeling of engine exhaust and intake systems in GT-POWER. This feature is new to GT-SUITE starting in version 6.2 and it will supersede GT-Muffler. In this class, users will learn how to use GEM 3D to model various exhaust and intake systems, including mufflers, resonators and airboxes. In addition, time will be left at the end of the day for open discussion and questions regarding acoustic analysis and any other topics relating to GT-POWER and GT-SUITE.

I. GEM 3D has been developed as a pre-processor to GT-POWER. It is a tool in which a model of a complete exhaust or intake system can be built, including multiple mufflers, resonators, airboxes and the pipes that connect them. This tool enables the user to build detailed and sophisticated models in a 3-D CAD-based tool. Shell shapes can be built by importing STL files. Internal parts (e.g. pipes, baffles, sleeves, perforates and wool) can be added to the mufflers and resonators. Once the system is complete, the entire system can be discretized into a system of components (e.g., pipes and flowsplits) that can be used in GT-SUITE. This includes the capability to build mufflers with pipes that bend at angles other than 90 and 180 degrees and pipes that can lie at any angle relative to the origin. The following topics will be covered:
   • Capabilities of the tool
   • Creating and importing shells
   • Addition of pipes, baffles, sleeves, perforates and absorbing wool
   • Visualization techniques (rotation, zooming, panning, viewing windows)
   • Importing final model into GT-ISE
   • Future advancements

II. Open forum for discussion of all GT-POWER and GT-SUITE related topics.
