This release also extends support of ARM architectures for scFLOW.
What's new in MSC Cradle CFD 2024.1 Summary

Battery electrochemistry enhancements
The P2D model, based on electrochemical equations, is now supported in the 3D mesh. This feature can be combined with cell-scale electric current analysis and the battery state variables can be treated homogeneously inside the cell. Directly study the effect of several cell parameters like the thickness of the electrodes or the location of tabs and their impact on the thermal performance of the cell.

A novel methodology for predicting fan noise (Ring of Dipoles)
scFLOW2Actran now has the functionality to predict fan noise. Multiple dipole sound sources arranged in a ring shape are created from the results of the fluid calculations and fan noise is predicted from those sources.
The benefits of this capability:
- Fan noise can now be predicted by the ring dipoles source method using a unique method that balances accuracy and cost.
- Storage costs are reduced because the sound source is created as dipole sources based on the blade pressure calculated by CFD, and rotational effects can be accounted for by arranging multiple dipole sources in a ring.
- The entire workflow, from CFD and acoustic meshing to source generation setup and solver execution, can be performed in a single user interface without leaving scFLOW.


Close
Multiphase flow
The non-equilibrium wall boiling model for subcooled boiling allows users to simulate transition boiling and the heat transfer from the wall to the vapour phase. The non-equilibrium wall boiling model improves the prediction accuracy of the thermal performance of heat exchangers, heat sinks, and direct immersion cooling systems.

Extensions to the Discrete Element Method (DEM)
The Edinburgh-Elasto-Plastic-Adhesion (EEPA) model has been added to our DEM capability. EEPA model is the standard model for simulating wet soils and allows to perform wet-soil simulation considering both compressibility and cohesion. This novel development has been tested in co-simulation with an off-road vehicle modeled in Adams: results of the simulation have been found in good agreement with experimental tests performed on soft soil.


Close
Productivity enhancements for turbomachinery analyses
In scFLOWPre, the modeling of centrifugal pumps can now create performance-specific outputs of turbomachinery directly in scPOST.
With these new capabilities, engineers will be able to:
- Directly perform the cutout and meshing of a single wing of centrifugal pumps on the 3D CAD geometry and eliminate preliminary work on CAD files.
- Visualise turbomachinery performance along with the flow field and pressure using the report function of scPOST.


Close
Preprocessor productivity enhancements
The latest version of scFLOWPre improves the productivity of octant generation workflows and the usability of large CAD data with thousands of parts. In scSTREAMPre, CAD data loading speed and geometry recognition functions make it easier to handle large CAD models with tens or hundreds of thousands of parts.
With these new capabilities, engineers will be able to:
- Automatically refine octant settings for curved surfaces with angle settings of the part/region. Testing demonstrated that meshing according to the prescribed protocols for automotive aerodynamics increased productivity by more than 10x.


Close
- Get more accurate part recognition for STL file imports and reduce the importing time of large CAD files in scSTREAM Pre. Testing demonstrated that the accuracy of shape recognition in the entire vehicle model was improved, and the loading speed increased by 1.4 times. The loading speed of large-scale CAD models with hundreds of thousands of parts increased threefold.
Accuracy and robustness
To improve the accuracy and robustness of Cradle CFD, the overset mesh has been improved. A convection term option has been added, and the boundary layer element insertion rate has been increased.
Benefits of these enhancements include:
- Improved overset mesh connections for symmetry and contact faces


Close
- Cutting-edge numerical treatments of convective terms (Nishikawa limiter) allow stable and accurate analysis of discontinuities like shockwaves and step changes in temperature, even when using a poor-quality mesh.
- Users can select between the previous limiter function (Hishida limiter) which prioritises stability, or the new Nishikawa limiter function for low dissipation and high accuracy.


Close
scSTREAM enhancements
- Condition regions can now be specified for cut cell parts. This allows initial temperature and heat source conditions to be specified for arbitrarily shaped parts with curved surfaces.


Close
New platform support
Extended support of ARM architecture for scFLOW: after releasing it for the Fujitsu A64FX architecture in 2021, both the solver and the mesher of scFLOW are now available for Ampere Altra processors (Neoverse N1) and AWS Graviton 3 processors (Neoverse V1). The release is scheduled for late June 2024.
Other enhancements
Cradle CFD Postprocessor improvements
- View turbomachinery performance output in scPOST.
- Eliminate discontinuity between the surface and interior temperature fields with a smooth display of temperature contours on cut planes in scSTREAM.
- Billboards created in scPOST can be viewed in Cradle XR.
Cradle CFD tools
- Get better interoperability with third-party CFD software with the ability to convert to/from CGNS files (ADF format) for boundary condition zone information for registered regions.
