CD-adapco STAR-CCM+ v9.02 CFD modelling software

CD-adapco has announced the release of STAR-CCM+ v9.02, the latest major release of its flagship simulation tool. The company focused on increasing users’ productivity and reducing simulation turnaround time, as well as a range of new application areas while making simulation more realistic for customers.

Computational fluid dynamics simulations involve the calculation of scalar quantities such as pressure, temperature, species concentration, turbulence intensity etc. In order to visualise these quantities CFD engineers have traditionally had to use ‘surfaces’, either the domain boundaries, artificial sections through the model or iso-surfaces. This process becomes increasingly difficult as the complexity of models increases. To address this, STAR-CCM+ v9.02 includes a new volume rendering capability that allows engineers to ‘see inside’ a flow field for the first time.

Another of the greatest challenges of engineering analysis is being able to understand how changes in geometry and flow features might influence a product&#rsquo;s performance. The introduction of the adjoint solver in STAR-CCM+ v8.04 allowed for direct access to sensitivity information from a single simulation, and in STAR-CCM+, v9.02 features have been added to broaden the applicability and improve the ease of use of the adjoint solver. Chief among these developments is the new tumble-and-swirl cost function implemented based on industrial users’ feedback.

Also released in the version is the new Dispersed Multiphase model - a lightweight, computationally efficient, Eulerian model which results in simulations that are much less computationally expensive than the Lagrangian equivalent, without the need for the full physics capability of Eulerian Multiphase (EMP).
