• Realizing the Benefits of Overset Mesh in Aerospace and Defense
    Overset Mesh technology (or Chimera Mesh, if you prefer) has been around for decades but has primarily stayed in a small, niche aerodynamics community. Although powerful in their own right, overset mesh tools to date have been purpose-built for specific applications and, let’s face it, a bit tricky to use. A live demonstration shows the entire Overset Mesh CFD analysis process – including geometry preparation, meshing, solving and post-processing. We...
  • Simulating Motion with Ease Using Overset Mesh
    Many real engineering applications which have not traditionally benefited from simulation in the past involve complex relative, interlocking motions that cannot be modeled by the simple rotational or translational models that are common in simulation software. This presents a headache to remeshing and morphing techniques. Overset mesh represents a paradigm shift in motion modeling that allows motion, however complex, to be easily simulated, be that a full...
  • Overset Mesh is one of the coolest technologies in STAR-CCM+ as it allows objects to move around your computational domain freely without tying your mesh in knots, be that an overtaking car, an excavator arm, or the complex multiple motions involved in a production line. The motion does not even have to be prescribed, the Dynamic Fluid Body Interaction (DFBI) model allows you to solve for motion, in six degrees of freedom or less, based on the forces and...
  • Overset Grids Technology in STAR-CCM+: Current State & Future Developments
    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...
  • Stage separation of a Delta Launch Vehicle using Overset Mesh. Animation shows the pressure gradients along a center plane section as the stages separate.
  • Tip Vortices from the rotors of an Osprey with pressure contours on the body

The revolutionary Overset Mesh capability in STAR-CCM+ is the first known implementation of this technology in a commercial code, bringing improved accuracy, reduced simulation time, improved designs and ability to accurately model complex motions to the hands of designers everywhere. With applications across multiple industries, Overset Mesh allows you to simulate complex motions or parametric studies, allowing you to discover better designs, faster.
