STAR-CCM+ V2.06: Optimizing Aerodynamic Simulations and the Engineering Process
CD-adapco announced the release of STAR-CCM+ V2.06, their Computational Fluid Dynamics (CFD) tool. Replete with new features, V2.06 marks a significant step on STAR-CCM+'s route to being the default code for all types of external aerodynamic calculations. Its combination of ease-to-use, an automatic simulation process, and powerful physics modeling means it optimizes the engineering processes in which it is deployed.
Planes, Trains and Automobiles
STAR-CCM+ is becoming the code of choice for external aerodynamicists: of planes, trains, and automobiles or oilrigs, ships and buildings. A combination of features, many unique to STAR-CCM+, makes it a complete toolkit for the CFD aerodynamicist. These include an automatic process from geometry to high quality hexahedral or polyhedral mesh, accurate solvers (implicit algebraic-multigrid and explicit multistage Runge-Kutta coupled solvers and a segregated solver), custom-made pre- and post-processing for external aerodynamics and unrivaled efficiency in handling calculations involving hundreds of millions of cells.
Optimizing the Engineering Process
Rapid and robust access to accurate CFD results oils the cogs of the engineering process. STAR-CCM+ achieves this through a range of unique features that cut preparation time for simulations while guaranteeing accurate results.
By automatically "shrink-wrapping" CAD geometry with a high-quality triangulated surface, STAR-CCM+'s surface wrapper fills holes, removes overlapping and non-manifold surfaces to cut the geometry preparation time from days to minutes. The advanced automatic hexahedral or polyhedral meshers then produce a high-quality computational mesh without further user intervention. Finally, the ability to solve, post-process, update the geometry and automatically rerun the calculation, all within a single coherent environment has reduced the time required for iterative design studies.
Powerful CFD in an easy-to-use environment
From its inception, STAR-CCM+'s goal has been to deliver powerful CFD in an easy-to-use environment. STAR-CCM+ V2.06 continues in this vein with further enhancements to the user interface, visualization when meshing and post-processing and a raft of new and advanced physics models. The main modeling advances improve calculations that involve unsteady flow and/or combustion, radiation and heat transfer in multiphase systems. Turbulence models enforce realizability, one of the benefits being to promote higher accuracy near stagnation and impingement regions; Large Eddy Simulation (LES) has been introduced and Detached Eddy Simulation (DES) capabilities have been enhanced to incorporate the Spalart-Allmaras delayed detached eddy model (or DDES); solar radiation has been introduced; the Volume Of Fluid (VOF) or free-surface model now allows heat transfer; and, STAR-CCM+'s wealth of combustion models now includes the Partially Premixed Coherent Flame Model (PCFM). Not to mention further enhancements to the boundary conditions and treatment of multi-species.
Automatic Fluid Volume Extraction
Also bundled with STAR-CCM+ V2.06 is the latest version of STAR-Design: CD-adapco's parametric geometry modeling tool, including Parasolid, IGES and STEP file import. This release includes fully automatic extraction of the internal or external fluid volume from CAD geometry. Fully compatible with STAR-CCM+ V2.06, STAR-Design is ideal for CFD engineers who need to manipulate CAD geometry prior to simulation, without access to a full 3D-CAD/PLM package.
STAR-CCM+ V2.06, bundled with STAR-Design, is now available from CD-adapco's User Services site , or from your local CD-adapco office.
