CD-Adapco Star-CD 4.24 (Win/Linx)



CD-adapco, the largest privately held CFD-focused provider of Computer Aided Engineering software, announced the release of STAR-CD and es-ice 4.24, the latest update to its industry-leading Internal Combustion Engine (ICE) simulation solution. This release forwards CD-adapco's mission to help their customers discover better designs faster with improved usability, increased accuracy and automation for ICE simulation.
Committed to maintaining leadership of In-Cylinder Engine analysis, CD-adapco continues to enhance capabilities and add functionality to STAR-CD/es-ice that will be critical to its automotive customers in the future.

In addition to refinements of existing combustion models, 4.24 delivers further improvements to the es-ice automated meshing processes and es-ice post-processing capabilities. This version also includes a pre-release of a new fully automatic meshing technology for full cycle calculations of 4-stroke gasoline and diesel engines.

The new meshing technology, which is accessible using es-ice, enables the user to generate accurate meshes automatically for full geometry, complete cycle calculations of 4-stroke gasoline and diesel engines. The mesh structure consists of prism layers at the boundary to capture near-wall gradients, an aligned mesh within the valve gap and a hexahedral mesh within the core of the model. A sequence of meshes is generated at distinct crank-angle positions during the engine cycle as a pre-processing step. These are subsequently morphed over a crank-angle range selected automatically to give optimum mesh quality. A fully automated process is used to minimize mesh generation time and allow the user easy control over mesh size. Results using this new technology indicate similar solutions to existing es-ice trimmed cell meshing, thereby providing users with alternative automatic meshing that is easy, fast and accurate.


The PVM-MF combustion model has been significantly enhanced, with new fuel chemistry libraries available for single and dual engine operation. These include gasoline, diesel, natural gas and ethanol, natural gas-diesel, gasoline-diesel and gasoline-ethanol. The dual-fuel libraries provide a way to accurately simulate dual-fuel engines that require the combined chemistry of both fuels.

The level-set (g-equation) combustion model can now use a variant of the AKTIM spark ignition model (referred to as SparkCIMM) to enable an improved simulation of the spark ignition process. This provides users with a much improved capability for modeling early flame development.

Ongoing development and consolidation of the ECFM-CLEH combustion model has also extended the capability to dual-fuel combustion using equilibrium and auto-ignition tables generated by DARS
