CFD software handles large models with ease

Written "from the ground up" using a modular programming style and the latest programming techniques, Star-CCM+ is an entirely new concept in CFD.

From its first release in 2004, Star-CCM+ has impressed the CFD community with its rapid pace of development.

Written "from the ground up" using a modular programming style and the latest programming techniques, Star-CCM+ is an entirely new concept in CFD.

Innovations such as built-in surface-wrapping, advanced automated meshing (creating either polyhedral or predominantly hexahedral control volumes) and the ability to "copy and paste" meshes and model setups between calculations have quickly established Star-CCM+ a reputation for producing high-quality simulation results in a single code with minimum user effort.

At the heart of the Star-CCM+ V2.04 is a process that links a powerful automated surface wrapper to CD-adapco's unique meshing technology.

The surface wrapper "shrink-wraps" a high quality triangulated surface mesh onto any geometrical model, closing holes in the geometry and joining disconnected and overlapping surfaces, providing a single manifold surface that can be used to automatically generate a computational mesh without user intervention.

This approach significantly reduces the number of man-hours spent on surface cleanup for problems that involve large assemblies of complex geometry parts - reducing the entire meshing process to hours instead of days.

In addition, Star-CCM+ V2.04 also includes a comprehensive set of surface-repair tools that allow users to interactively enhance the quality of imported or wrapped surfaces, offering the choice of completely automatic repair, user control or a combination of both.

The ability to efficiently handle large computational meshes is critical in successfully meeting the engineering challenges of modern industry.

Star-CCM+ is specifically designed to handle large models quickly and efficiently via a unique client-server architecture that seamlessly meshes and simultaneously solves and post-processes over multiple computing resources without requiring additional effort from the user.

The latest version also introduces an additional range of post-processing capabilities that are specifically tuned towards simulation in the building services and HVAC sectors.

Rather than just outputting generic engineering quantities Star-CCM+ can predict the level of comfort experienced by room occupants, using standard industry measures such as mean radiant temperature, predictive mean vote and predicted%age dissatisfied.

Star-CCM+ V2.04 also features new combustion, radiation and turbulence modelling capabilities, including the introduction of the V2F turbulence model.

The addition of a coherent flame model for premixed combustion is of particular benefit to users in the power-generation, gas turbine and oil and gas industries.
