Siemens Star CCM+ 2402| 3.4 Gb
The Siemens Digital Industries Software development team is pleased to announce the availability of Simcenter Star CCM+ 2402 (19.02.009). The new release provide engineers across industries with computational fluid dynamics (CFD) capabilities to go faster while modeling the complexity of today’s products. Leverage exciting new features to explore engineering possibilities and turn complexity into a competitive advantage. Simcenter STAR-CCM+ 2402 Released! What’s new? Model the complexity Run faster, more accurate industrial axial turbomachine simulations
Meshing turbomachinery blade passages with polyhedral meshes leads to a comparably high cell count. This typically manifests in increased run times of turbomachine aerodynamics simulations.
As the major solution structured meshes have been introduced in Simcenter STAR-CCM+ earlier. Those enable a faster turnaround time for axial machines making the mesh smaller compared to polyhedral and allowing a faster simulation time. Structured mesh also offers high-quality flow-aligned cells in the main blade passage, providing faster convergence in simulation and higher accuracy of the solution.
With Simcenter STAR-CCM+ 2402, we are further expanding the Turbomachinery structured mesh capability with support of blade fillets. These fillets can be either at the shroud or at the hub. A seamless user experience is guaranteed with the fillet being automatically detected as part of the blade surface input without any additional input.
Overall, the structured turbomachinery mesh, together with automatic fillet support leads to a further increased accuracy and faster time to solution with no additional user effort.
Tackle highly dynamic fluid loads leading to large solid deformations
For applications where a strong 2-way coupling between a dense fluid and a very flexible structure exists convergence and stability of a CFD simulation are very hard to achieve.
With Simcenter STAR-CCM+ 2402 we introduce a set of new features that enable exactly that kind of complex Fluid-Structure-Interaction simulations, where highly dynamic fluid loads lead to large deformations in the solid structure: The new Dynamic FSI stabilization method gives you very good control over the simulation with only one adjustable coefficient while being fully compatible with the solid stress load step solver. And with the Backward Differentiation Time Integration scheme now also being available for the solid stress solver, full kinematic consistency between solid and fluid is now ensured even for setups using 2nd order time integration.
This next-generation Fluid-Structure Interaction (FSI) modeling lowers the barriers to tackling highly dynamic strongly 2-way coupled FSI applications.
Enable applications involving radiation in participating media
Many applications in the food and beverage, medical, and process industry or in Additive Manufacturing, heavily rely on the volumetric interaction of radiation with a processed material. Hence to tackle such scenarios with CFD simulation, you need an accurate model of radiation absorption and scattering in the presence of a participating media.
With Simcenter STAR-CCM+ 2402 we are expanding the already existing Surface Photon Monte Carlo SPMC model (which only considers surface-to-surface radiation and ignores participating/volumetric effect) to a fully Volumetric PMC. Generally, PMC, a statistical method for solving the Radiative Transfer Equation, is considered one of the most accurate solution approaches. With the expansion to Volumetric PMC we enable a combined volumetric and surface radiation modeling and hence provide an even higher-fidelity approach.
This allows for more accurate modeling of complex phenomena like absorption and scattering of the radiation when it interacts with a participating media. To capture the interaction of radiation with liquids it can be run in conjunction with Volume Of Fluids (VOF). Thanks to the Hybrid Volume-Surface Scheme, users can efficiently use VPMC only in the region where absorption accuracy is needed, while keeping the rest with Surface PMC. This allows for impressive speed-ups of up to 37x compared to a pure Discrete Ordinate Method (DOM) solution.
VPMC is further expanding the already rich physics offering of Simcenter STAR-CCM+ for radiation modeling (DOM, Spherical Harmonics P1, Surface-to-Surface, SPMC) with the most comprehensive high-fidelity approach.
Explore the possibilities Unleash cross-functional synergy for Design Exploration
In a world of ever more complex products, the consideration of trade-offs across engineering disciplines is of fundamental importance to maximize product performance in a holistic way. Therefore, siloed untracked Design Exploration studies in a single CAE discipline pose the risk of unrealized performance potential.
With Simcenter STAR-CCM+ 2402 we are introducing an integration of the Design Manager in Teamcenter Simulation. The integrated solution will allow to get real-time updates and notifications on geometry changes, requirement changes, parameters, etc. from the other engineering teams which may affect your Design Exploration project.
The integrated Design Manager will help your teams accelerate time to market by leveraging Teamcenter capabilities for Design Exploration: Team members can directly access the right data in Teamcenter, ensuring traceability between requirements and results and leveraging a centralized database of project/product information. The embedded study launch from Active Workspace is further democratizing design exploration.
With the resulting enhanced cross-organizational collaboration you will be able to leverage the full potential via informed cross-functional product performance optimization.
Go faster Perform faster surface preparation for complex geometries
In external aerodynamics, CFD engineers need to strive for an efficient distribution of prism layers in exterior and interior parts of the vehicle. Using existing surface repair tools, the splitting of low y+ and high y+ surfaces can be a tedious process that can take hours or days depending on user experience and model complexity. Splitting of part surfaces is also important in any study when for example reporting of a quantity on a specific boundary or assignment of boundary conditions is desired.
In Simcenter STAR-CCM+ 2402, we are introducing an interactive classification tool in surface repair that expedites the splitting of part surfaces. The feature comes with an intuitive user interface and state-of-the-art algorithms that enable a fast and efficient classification allowing to save time. The tool can be applied to individual parts or a collection of parts that can have different tessellation levels.
The classification process is fast, and faces can be classified within seconds. The tool also allows the recording of a macro, for an even faster classification of distinctive design variants. Therefore, for external aero simulations, valuable surface preparation time can be saved as well as mesh count. This leads also to solver run time reduction with minimal drag count differences.
Time to mesh is a critical factor for fast overall CFD simulation turnaround time, especially for complex assemblies. The surface wrapper has proven to be a very powerful tool to automatically prepare watertight surfaces for subsequent surface remeshing and volume meshing. To date, surface wrapper employed shared memory parallelism.
In Simcenter STAR-CCM+ 2310, we are introducing the first phase of distributed memory (MPI) parallelized surface wrapper. In this first version, the surface wrapper pipeline up to gap closure has been parallelized.
Overall, the speedup of the new algorithm is up to 2.4x (total wall clock time – for MPI wrapper vs serial 1 core). Compared to legacy surface wrapper, there is roughly up to 43% reduction in wrapping time for a number of industrial cases. While the new MPI surface wrapper produces consistent results across different core counts, it locally offers an improved placement of gap closure faces for better mesh quality and generally can adhere better to the user input e.g., gap closure size.
Quickly automate sophisticated simulation workflows with Stages and the Automation node
To model the complexity of today‘s products and simulate those under real-world conditions, you need to implement sophisticated multiphysics CFD simulation workflows. Traditionally this task requires the usage of scripts or the cumbersome and error-prone data transfer from one simulation model to the other.
Simcenter STAR-CCM+ has been designed around a streamlined CAD-to-results pipeline providing fully integrated native automation capabilities. Building on this foundation, Simcenter STAR-CCM+ 2310 further extends the simulation automation intelligence with Stages. Stages enable you to handle multiple physics configurations in a single simulation, reducing the need for scripts. With a single click, you can stage different physics models, conditions – like interface or boundary conditions, and other settings. A staged object can have different settings for each stage. Objects that are not staged will keep the same values in all stages.
Applications immediately benefiting from Stages are the vehicle thermal soak, the just-released battery cell design template, and many more. Combined with Simulation Operations, this opens the rapid, consistent management of complicated simulation sequences. You can now manage complete stages of simulation setups and orchestrate their execution without manual intervention or Java macros, and share these workflows with your colleagues within one single simulation file.
To further boost your productivity, we are introducing a new node in the simulation tree: the Automation node. You will now benefit from one place in the simulation tree containing all automation aspects of the simulation workflow. This enables you to generate automated workflows faster and increases the discoverability of already-defined simulation workflows with better node organization and less scrolling.
Together Stages and the automation node, take the concept of an intelligent simulation file enabling end-to-end automation from CAD to results to the next level. Enabling you to explore more designs and handle complex multi-physics problems faster.
More efficient aero-vibroacoustic simulation workflow
Reduction of the CGNS file size and import time into Simcenter 3D through the new mapping method for the loosely coupled aero-vibroacoustics workflow. Example: Side-mirror induced noise assessment Vibro-acoustic simulations are typically undertaken in two steps: Following a CFD simulation in Simcenter STAR-CCM+, Simcenter 3D is used for the vibration and acoustic field analysis. The legacy workflow consisted of exporting a very large CGNS file with the CFD mesh and force information, importing that file into Simcenter 3D and mapping the results onto a coarse acoustic mesh.
With Simcenter STAR-CCM+ 2310, we offer a new option to map a fine CFD mesh to a coarser acoustic mesh directly in Simcenter STAR-CCM+ prior to data export. This Conservative Maximum Distance Mapping ensures consistent results to the legacy process by using the same mapping algorithm as in Simcenter 3D but significantly reduces the size of the resulting CGNS file. Depending on the case, the new CGNS file can be between 35% and 90% smaller with this new method, and the added mapping step has virtually no impact on the overall Simcenter STAR-CCM+ simulation time.
Whenever you are looking to couple a fluid solution in Simcenter STAR-CCM+ to a structural analysis in Simcenter 3D, you will benefit from a significantly slicker process and data transfer.
Accelerate EMP multiphase simulations with minimal loss of accuracy
Speed-up of multiphase EMP-LSI simulations through implicit multi-step. Application from the nuclear industry where cooling water is introduced leading to a counter current of displaced gas. Speed-up is shown with an increasing number of sub-steps together with the flowfield at the end of the simulation. Source: Gas-Liquid Counter-Current flow in PWR [Deendarlianto et al., NED, 39 (2012)] Multiphase simulations are often either computationally expensive or not sufficiently accurate. While smart hybrid multi-phase solutions offer the ability to apply the most effective approach in each state of the multiphase, the respective sub-models all need to be made as performant as possible for maximum throughput.
For this reason, in Simcenter STAR-CCM+ 2310, we have added implicit multi-step for Eulerian Multiphase (EMP) targeting Large Scale Interface (LSI) simulations mirroring equivalent capability previously added for VOF and MMP. This leads to more efficient EMP-LSI simulations by either reducing simulation time for a given level of accuracy; or increasing accuracy for a given runtime (budget).
Significant reductions in runtime can be achieved by carrying out N sub-steps within the flow timestep and then increasing the flow timestep by a factor N. This maintains the sub-step timescale associated with volume fraction transport at the same level (CFL number), but as the computational cost of a sub-step is a small fraction of the cost of a full flow timestep, there is a significant cost saving. Alternatively, this feature can be used to improve accuracy at little additional computational cost by adding sub-steps for a given flow timestep size.
Simulate more applications on GPUs
The benefits of GPU-enabled acceleration of CFD simulations are without any doubt; significantly lower simulation cost on the cloud, massively reduced energy consumption, and the replacement of hundreds of CPU cores with a GPU node. Over several release cycles, the excellent performance of Simcenter STAR-CCM+ on GPUs has been shown. It is of fundamental importance to expand the ability to leverage GPUs to more models, and hence more applications.
With Simcenter STAR-CCM+ 2310, we therefore continue the porting of solvers and capabilities to become equally available for GPU- and CPU-native simulations. With this release, you are able to leverage a GPU native coupled solid energy solver, a GPU implementation of Equilibrium Air equation of state, and of the Gamma-ReTheta transition model.
This means for example more efficient conjugate heat transfer, e.g. turbine blade cooling simulations, faster supersonic and hypersonic aerospace aerodynamics, and laminar-turbulent transition flows. Continuing our philosophy of one unified code base for CPUs and GPUs you can rest assured that GPUs will deliver CPU-equivalent flow solutions.

Optimize cabin design via fully integrated industry-standard passenger comfort assessment
Thermal comfort of passengers is a huge end customer satisfactory factor for any given vehicle. While internal combustion engine-powered vehicles made it comparably easy on HVAC and system energy management engineers thanks to the vast amount of excess heat, electric vehicles require a way more diligent treatment of energy and heat in the trade-off of comfort, safety, and range.
With Simcenter STAR-CCM+ 2310, you can now optimize vehicle cabin design and HVAC systems via a fully integrated set of industry-standard passenger thermal comfort assessment models. A new state-of-the-art thermoregulation model is now available to calculate the thermal response of the human body as a function of the conditions in the cabin (radiation, convection). The model also accounts for physiological factors, such as metabolism’s activity level, and use them to accurately compute the skin temperatures throughout the body. Said temperatures are then used to calculate the Dynamic Thermal Sensation (DTS) and the Predicted Percentage Dissatisfied (PPD) global comfort indexes as well as the Equivalent Homogeneous Temperature (EHT) local comfort indexes. These are widely recognized industry standard metrics that are crucial to assess passengers’ comfort perception overall via DTS and PPD as well as locally for each main body part via the EHT. All the mentioned new models are fully integrated with the latest automation capabilities of Simcenter STAR-CCM+.
This allows you to build leaner and more efficient end-to-end workflows for cabin design studies.
Access practically unlimited compute resources from within your simulation environment
