Engineering Simulation Software offers overset meshing capability.
Press Release Summary:
March 21, 2012 - With overset meshing capability, STAR-CCM+ v7.02 allows user to generate individual mesh around each moving object, which then can be moved at will over background mesh. Indirect mapped interface allows use of non-conformal meshes between solid and fluid domains, minimizing time required to set up conjugate heat transfer simulation. Providing complete history of simulation, Solution History feature lets engineers record, store, compare, and visualize results from any analysis type.
Original Press Release
Engineering Simulation Software, STAR-CCM+ v7 Changes the Game. Again!
Press release date: March 8, 2012
For the past 30 years, the ability of engineers to perform Computational Fluid Dynamics simulations of the interaction between multiple moving objects has been severely curtailed by the need to generate an interconnected mesh between the objects. Not only did this requirement make the creation of "moving mesh" simulations an intensive manual process, it also often rendered it impossible in the case of objects with extreme ranges of motion or with very close interaction. The release of STAR-CCM+ v7.02 changes this forever with the introduction of a new Overset Meshing capability. Overset Meshing (sometimes called "overlapping" or "chimera" meshing), allows the user to generate an individual mesh around each moving object which then can be moved at will over a background mesh. The Overset Meshing capability is fully compatible with the full range of unstructured meshing options in STAR-CCM+. With no need to worry about interconnecting meshes or cell distortion, Overset Meshing brings genuine moving object simulation within the grasp of all engineers. Overset Meshing can also be used for parametric studies, steady or unsteady simulations, providing an easy way to reposition or replace objects in order to study multiple design configurations. "The term 'paradigm shift' may be overused, but the introduction of Overset Meshing in STAR-CCM+ v7.02 truly offers a new way of approaching CAE. Overset Meshing revolutionizes the entire analysis workflow while opening a whole new range of application areas to simulation," said Ercolanelli. Indirect Mapped Interfaces
STAR-CCM+ v7.02 also revolutionize the simulation workflow for conjugate heat transfer (CHT) simulation (those in which temperatures are solved for both fluid and solid regions). The new Indirect Mapped Interface allows to using non-conformal meshes between solid and fluid domains. Not only does this reduce the time required to set up a CHT simulation, but it also has the potential to greatly increase the accuracy of the simulation results by allowing the user to specify the most appropriate mesh for each region without worrying about making them conformal at the interface. Solution History
The Solution History is an entirely new feature of STAR-CCM+ v7.02, allowing engineers to review and explore the analysis results space by providing a complete history of a simulation, both in terms of changing results and changing design configuration. For the first time, engineers can record, store, compare, and visualize results from any analysis type. Results from multiple simulations may be recorded in a single simulation history file and easily replayed. Since the user can choose exactly which data is stored for each configuration or time-step, all this can be achieved without a large storage overhead. The Solution History feature also provides a way of comparing multiple design configurations in a single STAR-CCM+ session. See STAR-CCM+ v7 at the STAR Global Conference The STAR Global Conference (March 19-21, 2012, the Netherlands) is the official launch event of STAR-CCM+ v7.02, and will include demonstrations of all the new features and a dedicated training course designed to orient users with the new software.
