Fully Automatic Topology & Meshing Fully Automatic Topology & Meshing

ANSYS TurboGrid software includes novel technology that targets complete automation combined with an unprecedented level of mesh quality for even the most complex blade shapes. The desired final mesh size is defined (and, optionally, the blade boundary layer resolution), and all the other steps are performed automatically to produce a mesh of extremely high quality. Grid angles are exceptionally good, mesh sizes transition smoothly, and high aspect-ratio elements are generated in the near-wall regions to resolve these regions efficiently and capture boundary layer flows accurately.

High-quality meshes are generated using unique topology and meshing technology in ANSYS TurboGrid which automatically adapts to span-wise changes in blade shape. The examples show blade-to-blade plots of meshes at different span-wise positions of an axial turbine and a centrifugal compressor with splitter blades.

ANSYS TurboGrid software offers a user-friendly point-and-click environment with display functions familiar to blade designers, including 2-D blade-to-blade and meridional planes for viewing flow path and blade position. The view is updated automatically with each input to reflect the latest changes.

Automated Tip Clearance Meshing Automated Tip Clearance Meshing

For blades with clearances at the shroud, or even at the hub, ANSYS TurboGrid provides a solution. Users can specify the amount of tip clearance in numerous ways: for example, as a percentage of span or at a specified distance from the hub or shroud. The grid in the tip can be either matching or nonmatching along the center of the blade thickness, ensuring optimal grid quality and accurate prediction of blade tip flow.

Rapid Mesh Quality Feedback Rapid Mesh Quality Feedback

ANSYS TurboGrid provides immediate feedback on mesh quality, based on criteria such as grid skew angles, mesh expansion rates, and aspect ratios of mesh elements. Any mesh elements that do not meet target quality criteria are highlighted, guiding the user in adjusting user input and controls accordingly.
