With increasing the speed of manufacturing design cycles and maintaining product integrity, PLM software became the center of product lifecycle management. At the same time, to improve engineering productivity, front-loading simulation is more and more desired. These two trends make simulation tool need to have high affinity with PLM software, so that simulation is “connected” with other organizational functions, designing, machining, assembling, quality, … deeper, stronger, and organically.
PLM software was developed around the 3D-CAD environment because 3D-CAD made it possible to share the same product data in the entire organization, BUT, there is a disconnection between “product data” and “simulation”. This is caused by historical aspects. The simulation tool was developed as an analysis tool, not as a design tool, and it treats 3D-CAD as a geometry preparation tool for analyses. Most often, the simulation tool requires “fixes” of 3D-CAD geometries so that the simulation tool can mesh the geometries, then perform its analysis. And it ended up “modifying” product data just because for the analysis. This disconnection between 3D-CAD product data and simulation date makes simulation tool to have a very low affinity with PLM software, such as Teamcenter.
There are three main simulation tools, Finite Element Analysis (FEA) tool, Multi-Body Dynamics (MBD) tool, and Computational Fluid Dynamics (CFD) tool. And as for CFD tool, we have CFD tool which has high affinity with Teamcenter, called FloEFD (CAD-embedded CFD tool). This presentation shows the differences in meshing technology between FloEFD and traditional CFD tool, which causes the differences in affinity with PLM software and other benefits of FloEFD meshing technology over the traditional CFD meshing technology, such as meshing robustness and shorter CPU time for analysis.
