2D simulation is a great way to test out designs and boundary conditions, personally I use it all the time when I am setting up a complex case for the first time or just playing with a new feature. Historically in STAR-CCM+ there wasn’t a pipelined way to build and run 2D meshes, but now with version 9.06 there are two new features that will put that problem to rest.
Being able to plot solution quality metrics while your simulation is running, that is, live-processing as opposed to post-processing, is one of the most distinctive functional aspects of STAR-CCM+. This lets you critically interrogate your results and make changes on-the-fly, thereby increasing your productivity. There are many very capable 3rd party plotting tools available. However working with them requires exporting and importing data, adding several steps to your workflow and making it difficult to automate. Still, there’s an argument to be made that plotted results need to be legible and, to a degree, customizable. With this release, we have targeted visual plot quality as an area for improvement.
When we initially consider the analysis of unsteady phenomena in turbomachinery, aeroelasticity and aeroacoustics, we’re quickly confronted by the simulation cost – transient analyses by their very nature will simply take longer to run compared to steady ones. And for these types of problems, where the simulation objectives (understanding of flutter and limit cycle oscillations for example) demand a time-dependent treatment, the time steps need to be small and the physical time required can be long. Not that this isn’t challenging enough, usually, the entire machine needs to be modeled at a high level of spatial fidelity, thereby driving up the size and cost of the analysis even further. But, all is not lost– enter the Harmonic Balance method, first introduced with STAR-CCM+ 4.04 in 2009, capable of delivering at least a 10-fold reduction in your time to a solution. And, that’s not the only benefit to be had with this approach – it’s possible to mesh just a single blade passage through all the blade rows in your machine and obtain a solution which varies from blade-to-blade, capturing critical blade row interactions.
STAR-CCM+® v9.06 breaks new ground in biomedical devices, aeroacoustics, chemical processes and many other sophisticated modeling applications. New York and London. October 29, 2014 CD-adapco™, the largest privately held CFD focused provider of Computer Aided Engineering software, today announced the release of STAR-CCM+ v9.06. The new release allows engineers to get simulations closer to the final product by accounting for factors that are likely to significantly influence the performance of a design in operation. Throughput improvements make this level of accuracy a practical reality. “We...
