This property specifies the bladerow number for the bladerow that is immediately upstream of the current bladerow. Set the file name and the hub curve as well as the number of points per section. The number of sections and number of points per section can also be set.

Any mesh elements that do not meet target quality criteria are highlighted, guiding the user in adjusting user input and controls ansyz.

Do the same for the shroud. Create and select the blade feature.

This property specifies how the inlet points are positioned in TurboGrid. The view is updated automatically with each input to reflect the latest changes. Meshing Inlet Domain If this property is selected, TurboGrid will generate an inlet domain as part of the mesh.

The export features can be found in the feature definition node. Such a setup is directly ready for highly automated shape optimization workflows. If this property is selected, TurboGrid will generate an inlet domain as part of the mesh.

If you want a given bladerow to contain more than one blade geometry for example, main blades with splitter bladescreate one ExportPoints feature for each unique blade in the bladerow, with each ExportPoints feature based on the same FlowPath and given the same Bladerow Number.

High-quality meshes are generated using unique topology and meshing technology in ANSYS TurboGrid which automatically adapts to span-wise changes in blade shape. This command opens TurboGrid and loads the geometry and state, regenerating the mesh if appropriate. Overview ANSYS TurboGrid creates the self-consistent meshes that are critical to minimize the mesh dependence when assessing differences in performance predictions between designs.

Set a name and choose the parametric blade surface from your project. Minimum Face Angle The minimum face angle of the mesh is displayed here. You can enter a name for a system when you first create the system. Tip clearance mesh detail near leading edge of radial compressor 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.

Saving a project enables you to re-open the project on the machine that originally created it. 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. Select this option if you want to open TurboGrid more quickly to make changes to the mesh settings without first regenerating the mesh. To model a series of consecutive bladerows in a turbomachine, you should define a series of ExportPoints features associated with the same FlowPath feature, with Bladerow Numbers in numerical order lowest number at the inlet end of the machine.

The same topology is then automatically adapted to variants of a design, ensuring that the mesh produced is consistent.

Drag a Geometry system from the toolbox to the Blade Design cell. Tailored for Turbomachinery 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.

Double-click a Geometry system in the toolbox to add a Geometry system to the schematic, then drag from the Blade Design cell to the Geometry cell to connect the systems. Use this information as a guide when specifying the Flowpath and Bladerow properties described below. As a result, TurboGrid minimizes mesh dependencies when assessing differences in turhogrid predictions between designs. This command opens TurboGrid and loads the geometry and state, but suspends the Topology from regenerating.

Elements not meeting selected quality criteria can be highlighted directly by the user, guiding the user to adjust input and controls if required. Then check out the following quick guide which shows you the export procedure.

Edit each cell in sequence, starting from the upstream cell, and use the associated software to provide the required data. Add a Geometry system to the BladeGen system by any one of the following methods:.

Create and select the TurboGrid contour feature.

You can also initiate a rename operation by right-clicking the upper-left corner of the system and selecting Rename from the shortcut menu. ANSYS TurboGrid automates the production of high-quality hexahedral meshes needed for blade passages in rotating machinery. This is convenient if you do studies since these files are then stored in the corresponding design directory of the variants.

Tailored for Turbomachinery 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 geometry can be loaded from the File menu in TurboGrid, or it can be specified by linking a Geometry or Blade Design cell upstream of the Turbo Mesh cell. Are you interested in CFD-related topics and design optimization? Click here for instructions on how to enable JavaScript in your browser. ANSYS TurboGrid maximizes productivity when assessing many blade geometry variants with scripting for batch mode operation. If this property is selected, TurboGrid will generate an outlet domain as part of the mesh.

Use the Refresh command in the context menu to update the list after linking. Drag a Geometry system from the toolbox to the Project Schematicthen drag from the Blade Design cell to the Geometry cell to connect the systems.

Configure how to export the blade. ANSYS TurboGrid provides immediate feedback on mesh quality, based on criteria such as grid skew turbohrid, mesh expansion rates, and aspect ratios of mesh elements. Tip clearance mesh detail near leading edge of radial compressor. This property specifies how the outlet points are positioned in TurboGrid. The machine is eligible to be analyzed by Vista TF.

No matter if you consider a centrifugal or axial blade — as a result, we receive a single blade surface: ANSYS TurboGrid creates the self-consistent meshes that are critical to minimize the mesh dependence when assessing differences in performance predictions between designs.

Outlet Domain If this property is selected, TurboGrid will generate an outlet domain as part of the mesh.
