The biggest constraint that engineers face in exploring more of the design space in less time, with respect to CAE, is the CAD to mesh process. There are multiple ways of approaching this, here are a few of them:
Using a direct CAD to STAR-CCM+ connection instead of importing geometry allows users to avoid spending time on swapping geometry, checking surface diagnostics to ensure the geometry is clean, and/or wrapping the geometry. Instead, users can change the CAD (enter a different number for an exposed design parameter – or move a sketch point, move a body, change a radius, length, etc within CAD), click mesh, wait for the meshing to complete, and click run. Multiple design iterations can be manually run much faster this way.
To further speed up this process, you can automate this design exploration process. One approach would be to develop a java macro to automatically run specific simulations (in addition to other functions like saving pictures, sim files, etc). While this does require additional licensing, it does require your time to develop this.
To avoid this, our optimization add-ons/software can enable you to automate simulation runs and data collection while also intelligently searching the design space using a searching algorithm. This, in short, allows engineers to find better designs, faster. It also expands the searched design space from a handful of designs, to potentially hundreds or thousands of simulations. See our optimization sections for more information.
