Changing the Display Colors 1. Editor Buttons 1. Using Help 1. Select a working directory. Click the TurboGrid You can access the color options by going through the following steps: 1.

The Options dialog box appears. Click OK. The settings are stored in the database each time the Apply button is clicked. Context-sensitive help is provided for many of the object editors and other parts of the interface. To invoke the context-sensitive help for a particular editor or other feature, ensure that the window is active, place the mouse pointer over the feature, and press F1.

Not every area of the interface supports context-sensitive help. Chapter 2: Rotor 37 This tutorial includes: 2. Overview of the Mesh Creation Process 2. Preparing the Working Directory 2.

A clearance gap exists between the blades and the shroud, with a width of 2. Within the blade passage, the max- imum diameter of the shroud is approximately 51 cm. Such information includes the location of the geometry files hub, shroud, and blades , the mesh topology type, and the distribution of mesh nodes. All of the data that you provide is stored in a set of data objects known as CCL objects.

You can use the object selector to select and edit the CCL objects; the objects are listed from top to bottom in the standard order for creating a mesh. The user interface also has a toolbar for selecting and editing the CCL objects; the icons are arranged from left to right in the standard order for creating a mesh.

Preparing the Working Directory Regardless of whether you use the object selector or the toolbar, you should generally follow this se- quence when creating a mesh: 1.

Define the geometry by loading files and changing settings as required. Define the topology by choosing a topology type and optionally changing other topology settings. Optionally modify the Mesh Data settings that govern the number and the distribution of nodes in various parts of the mesh. If you plan to make a fine high-resolution mesh, you can optionally set the mesh density at a later time in order to minimize processing time while establishing the topology.

Keep in mind that changing the mesh density can affect the mesh quality. Improve the topology on the hub and shroud layers as required. Optionally add intermediate 2D layers that guide the 3D topology and mesh. If you do not add layers at this point, they will be added as required when you generate the mesh. Adding them early gives you a chance to check and adjust the 2D mesh quality on the intermediate layers before generating the full 3D mesh.

Issue the command to generate a mesh. Check the mesh quality. As required, adjust the topology type and distribution, and Mesh Data settings. If you make changes, go back to the previous step. Save the mesh to a file. Preparing the Working Directory 1. Create a working directory. ANSYS TurboGrid uses a working directory as the default location for loading and saving files for a particular session or project. Defining the Geometry The provided geometry files, which consist of a BladeGen.

As you work through this tutorial, you will create a mesh for a blade passage of a radial compressor blade row using the Automatic Topology and Meshing ATM Optimized feature. A typical blade passage is shown by the black outline in the figure below. Chapter 5: Axial Fan 5. Preparing the Working Directory 5.
