IBMeshMotion and Performance Improvements
The IBMeshMotion module has been enhanced to support the use of Function1 objects for both linear and rotational movements, replacing the previous use of scalars.
These updates offer the following benefits:
- Enabling time-dependent motion of meshes
- Supporting nested and superimposed motion of objects
Additionally, several optimizations have been implemented to improve overall performance:
- Enhanced efficiency of model equation implementations
- Reduced overhead for integrators by creating and resetting them only when necessary
Solver and Model Updates
Several key solvers and models have been updated to enhance their functionality and performance, reflecting the ongoing efforts to improve simulation accuracy and computational efficiency.
Compressible Flow Solver
The cfdemSolverRhoPimple has been updated to the OpenFOAM-10 code base, offering improved compatibility and performance for compressible flow simulations. This update ensures that the solver benefits from the latest advancements in the OpenFOAM framework, enhancing its capability for simulating complex fluid dynamics.
Chemistry Solver
Similarly, the cfdemSolverChem has been upgraded to the OpenFOAM-10 code base. This update not only improves performance but also aligns the case setup with cfdemSolverRhoPimple, simplifying the overall configuration process. Additionally, the models have been updated to better account for varying particle mass in species and mass transfer processes, improving the accuracy and versatility of chemical reaction simulations.
Volume-of-Fluid Multiphase Solver
The cfdemSolverInter has been extended with new functionality to handle phase change and resolved particles, offering enhanced capabilities for multiphase flow simulations. This update replaces the previous solvers, cfdemSolverInterDyMPC and cfdemSolverInterIB, consolidating features and streamlining the setup process while providing more robust simulation options for complex multiphase interactions.
These updates collectively contribute to a more efficient and accurate simulation experience, ensuring that the solvers can handle increasingly complex physical phenomena with greater precision.
