Fully Automatic Topology and 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.

Automated Tip Clearance Meshing

For blades with clearances at the shroud, or even at the hub, ANSYS TurboGrid also 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 non-matching along the center of the blade thickness, to ensure optimal grid quality and accurate prediction of the blade tip flow.

Tailored for Turbomachinery

ANSYS TurboGrid 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 the flow path and blade position. The view is updated automatically with each input to reflect the latest changes.

Rapid Mesh Quality Feedback

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

Red highlights indicate mesh elements in which selected grid quality criteria are not met; small adjustments to control points can then be applied to achieve the desired quality
