Overset Grids Technology in STAR-CCM+: Current State & Future Developments

Printer-friendly versionPDF version

In this presentation the overset grids methodology implemented in STAR-CCM+ will be first described, including its distinct features compared to similar approaches known from literature (like applicability to arbitrary polyhedral grids and implicit coupling of all grids).

Next the access to this feature through the user interface will be explained. The advantages of overset grids compared to alternative approaches when performing parametric studies or simulating motion of bodies relative to each other will also be discussed.

Several examples of the use of overset grids for both steady-state and transient flows around static or moving bodies will be presented to illustrate the various features of overset grids, including marine, automotive and aerospace applications.

Finally, future developments of this technology and new application areas will be highlighted.
