CD-adapco is pleased to announce the release of 4.20.027 of STAR-CD and es-ice IC Engine simulation software. The 4.20.027 release gives users extensive new physics capabilities and pre-processing developments to deliver rapid and more accurate in-cylinder simulation.

In es-ice, template automation has been further improved with an easier ability to capture geometric features in the 2D mesh giving improved cell quality for both the trimming and smoothing. In addition, the GUI supports dual and 2-component fuel specification so that setting up gas/diesel pilot, ethanol blend, or similar simulations is simplified. Post processing has been further enhanced with the optional generation of a PowerPoint summary report which includes details such as engine parameters, analysis statistics, integrated results, etc.

4.20 sees the first release of a new combustion model within STAR-CD, namely the Progress Variable Model – Multi-Fuel (PVM-MF). This model integrates the level-set (g-equation) model and flamelet-based approach into a single consolidated model, thereby removing the restriction of either premixed or diffusion-controlled combustion inherent in the individual models. The PVM-MF model allows for all modes of combustion to coexist – premixed, diffusion and autoignition. Users that wish to continue using the existing g-equation and DARS-TIF flamelet model may do so.

Customer experience with the ECFM-CLEH model during the past year has been extremely encouraging. Evolution of this model together with the addition of the NORA (Nitrogen Oxides Relaxation Approach) NOx model, which accounts for all of the nitrogen oxides, and ISSIM (Imposed Stretch Spark Ignition Model), an Eulerian spark-ignition model, which are available in the 4.20 release are demonstrating further advantages in the predictive capability of these phenomena.
