As part of the existing meshing process, the flow path is parameterized to obtain a spatial coordinate system that is suitable for meshing algorithms. In the previous release, the parameterization process uses a Block-structured method. In the current release, the parameterization process has a new available method: Locally-adapted.

A new user preference, Use Locally-Adapted Flowpath Parameterization By Default, controls which parameterization method (Block-structured or Locally-adapted) applies by default for new cases. For details, see TurboGrid Options in the TurboGrid User's Guide.

Note that the Machine Data object's Flowpath Parameterization Type setting controls which parameterization method applies for a given case. For details, see Flowpath Parameterization Type in the TurboGrid User's Guide.

Selecting the new CAD Surfaces Are Watertight option enables TurboGrid to make use of topological connectivity data stored in a CAD file, typically resulting in mesh generation that is faster and more reliable compared to when the option is not selected. For details, see Complex Blade End Tab in the TurboGrid User's Guide.

The Suppress Inflation Layers on Named Selections settings control the presence of inflation layers in the unstructured mesh block for a complex blade end. For details, see Setting Descriptions for Complex Blade End Mesh Data Objects in the TurboGrid User's Guide.

In the Mesh Data settings for a complex blade end, the new Inflation Layer Mode setting provides an option (Last Aspect Ratio) to limit the change in cell aspect ratio where the outermost inflation layer interfaces with the interior mesh. The setting's other option (Constant Expansion) gives the behavior of the previous release. For details, see Setting Descriptions for Complex Blade End Mesh Data Objects in the TurboGrid User's Guide.

The Global Size Factor (see Method in the TurboGrid User's Guide) affects the unstructured mesh blocks of complex blade ends closer to how it affects the passage mesh, in terms of element edge length and element count.
