Summary Cradle CFD 2025.2 release highlights

-    Use scFAST, Cradle CFD's first GPU-native solver optimised for HPC GPUs for significant simulation speed increases over CPU platforms.

-    Simulate keyhole laser welding, predict penetration profiles, and optimise welding conditions with laser beam welding in scSTREAM.

-    Generate and visualise 3D-ROM files trained on transient datasets and take advantage of new POD interpolation schemes via scripting.

Other product enhancements

-    Improve battery safety with ECM battery parameter identification and a lumped vent model for efficient battery safety analysis.

-    Model preparation is faster and easier with automatic octant mesh refinements and new thin mesh controls.

-    Take more control over post-processing for turbomachinery and gain a better understanding of results with new features for adjusting meridional planes, radial planes, and contours of turbomachinery parts.

ECM Parameter Identification Tool

scFLOW can now identify the parameters of an Equivalent Circuit Model (ECM) by fitting Hybrid Power Pulse Characterisation (HPPC) test data executed under various ambient temperatures. Easily reproduce the output voltage of a real battery over a wide range of temperatures and the state-of-charge.

Lumped Vent Model

A new, simplified concentrated parameter model reproduces the effects of the air volume inside the battery unit. The battery interior volume is modelled as a single non-dimensional gas reservoir, receiving the venting gas from the cell and releasing it through the casing valve when the pressure reaches a given threshold. This lumped model simulates the effects of vent gas on battery thermal runaway with a much lower computational cost compared to a direct 3D CFD simulation.

Transient 3D-ROM Support in scFLOWpre and scPOST

Easily generate and display 3D-ROM (3DR files) trained with a transient dataset (via ODYSSEE). In the scPOST "3drom tab", users can modify the simulation parameters and interpolate them to visualise results, while the "cycle tab" controls cycles to browse different time frames (time-based interpolation is not currently available). New interpolation schemes for POD have also been added via scripting.

Meshing Enhancements

Several new features and performance improvements have been added in Cradle CFD 2025.2. Parallel facets creation greatly speeds up voxel fitting mesh generation, and a new injection process reduces the time it takes to add boundary layer elements. Automatic refinement features for both voxel fitting mesh octants and thin meshes reduce mesh setup time by dramatically reducing the number of inputs required to properly capture narrow spaces and gaps between parts.

New GPU-native CFD solver: scFAST

Cradle CFD 2025.2 includes the first release of a new GPU-native CFD solver. Both density-based and pressure-based (incompressible) solvers are available. Features are currently limited to single phase gas simulations with no mesh deformation or moving parts. scFAST was developed and optimised for HPC GPUs, and officially supports Ampere, Hopper and Grace-Hopper architectures. scFAST offers significant speed increases compared to HPC CPU-powered platforms, especially when dealing with large-scale models.

Solidification and Melting

scFLOW multiphase flow capabilities have additional capabilities for simulating solidification and melting phenomena. The solid-liquid mixture region is treated as a pseudo-porous medium, where velocity variations are modelled based on porosity.

Laser Beam Welding

Keyhole laser welding is a new capability in scSTREAM. Currently, it supports only the welding of similar materials. This capability predicts the penetration profile, keyhole behaviour, and heat-affected zone (HAZ). Optimal welding conditions are studied by evaluating changes in laser power, travel speed, beam size, and welding trajectory. The calculated weld penetration profile can be exported and used in structural analysis.

Phase Change Material

It is now possible to model phase change within given solid parts. The state of phase change can be easily displayed via a solid phase fraction contour. This feature is also available for cut-cell and heat-conduction panels. The latent heat dependency on temperature is included in the calculation. This new functionality offers a faster and more stable calculation method compared to modelling the phase change via variable material properties (original method).

Enhancements for Turbo-Machinery Post-Processing

Several new functionalities have been added to scPOST for turbomachinery post-processing in Cradle CFD 2025.2:

-    Meridional plane mesh control

-    Meridional plane trimming

-    Automatic pressure/suction radial planes

-    Improved contour drawing controls

Cut-plane Arbitrary Movement Function

In scPOST, users can now set up cut-planes positions relative to time via a csv file. Cut-planes movement can be synchronised with respect either to the distance from a starting point or the elapsed time. With the ability to maintain the relative position between cut-planes and the camera view, users can display and monitor sectional contour Descriptions that follow specific phenomena occurring in the simulation.

Other Features

scFLOW

-        Overset Mesh Connection Enhancement: The scFLOW overset mesh connection has been improved to better resolve cases where thin solid parts are present.

scSTREAM

-        Shape-fitted Anisotropic Heat Conduction: Heat conduction properties for solid parts in scSTREAM can now be set relatively to radial/tangential directions.

-        Multi Reference Frames (MRF) Algorithm (Beta): A new feature to simulate rotating parts uses stationary meshes, reducing computational cost compared to a sliding mesh approach.
