Reduce geometry preparation and meshing time from months to hours
STAR-CCM+ quickly, easily and efficiently prepares and generates meshes on the most complex geometries. With both manual and automatic surface preparation tools as well as state-of-the-art parallel polyhedral and trimmed cell meshing, STAR-CCM+ offers the ultimate balance between user control and automation.
  • The Advancing Layer Mesher uses a pseudo-structured mesh approach to generate layered, primarily structured grids from wall boundaries beyond the boundary layer. This meshing approach is suitable for computations involving bow shocks as depicted in this simulation of the re-entry of the Crew Exploration Vehicle.
  • STAR-CCM+ offers a range of state-of-the-art technologies for volume mesh generation including the pioneering polyhedral mesh type as shown here on a Bell 407 helicopter. Polyhedral meshes are fast to converge, easy to generate and more efficient than tetrahedral meshes.
  • STAR-CCM+ provides advanced automated meshing capabilities which ensure that the fidelity of a complex geometry is retained in the simulations and no simplifications are involved. Shown here is a volume mesh with conformal meshing between the components of a motherboard.
  • When handling complex structures, STAR-CCM+'s surface wrapping capability enables the user to automatically, and quickly, create a solution domain for the flow around the imported solid body. Here, the surface wrapper was applied to an intricate oil rig geometry.

The STAR-CCM+ meshing pipeline

STAR-CCM+ employs a pipeline methodology to ensure that the path from initial geometry to mesh can be easily and robustly automated. Each step in the meshing process may be executed in sequence, or independently, with a common set of user parameters. The automated meshing process may be carried out interactively, in batch or remotely.

A complete set of tools for surface preparation and volume extraction

STAR-CCM+ gives you choice and flexibility when preparing surfaces for volume meshing. An extensive set of operations are available for surface preparation including: error diagnostics, fine grained manipulation of surface primitives, topological identification, defeaturing, boolean and imprinting operations on triangulated surfaces.  STAR-CCM+’s revolutionary and unmatched surface wrapping technology enables you and your team to reduce you surface preparation times by several orders of magnitude. Fully automatic and with the ability to reliably handle the most complex geometries and large assemblies, it has justifiably earned a reputation as the best in the business.

 

Leverage the Power of Parallel Computing

In STAR-CCM+, both the polyhedral and trimmed cell meshes allow you to push the boundaries of your simulation capabilities by automatically distributing the meshing process across all of your CPU’s.  You can build the same meshes faster or build meshes that are not limited by the RAM in just one machine.  Not only has STAR-CCM+ broken the parallel barrier for singe mesh operations, but also has introduced Concurrent Per-Part Meshing, for cases with large numbers of parts.  Concurrent Per-Part Meshing will look at all of the components you have selected and will hand each part to its own processor, almost like a card dealer, when one part is meshed STAR-CCM+ hands it another until all the parts are done.  So no matter if you want a 100,000,000 cell mesh or to mesh 10,000 parts STAR-CCM+ has an efficient way to handle it.

A flexible choice of volume mesh

STAR-CCM+ offers a range of technologies for volume mesh generation including the pioneering polyhedral and trimmed hexahedral mesh types. For multi-domain studies such as conjugate heat transfer and FSI, fully conformal meshes can automatically be created. Prism layers are robustly generated to ensure accurate capture of boundary layers. A number of specialized meshers are also available including generation of prismatic elements for thin objects, generalized cylindrical geometries and boundary extrusion
