eshing 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.
