Geometry


Info

This page goes through the geometry steps for the Supersonic Flow Over a Wedge in the SpaceClaim geometry engine included with ANSYS Workbench. For instructions on creating the geometry using DesignModeler, see this page.

Some tips:

  • As you follow along in Ansys, you can switch between the video and Ansys easily using Alt+Tab if you are on a MS Windows computer.
  • In newer Ansys versions, there is a new Sketch tab in SpaceClaim with slight changes in the sketching procedure which you should be able to able to figure out with a bit of poking around.  
  • In SpaceClaim, you can zoom in/out using the mouse wheel, rotate using MMB (middle mouse button) and translate using Ctrl+MMB.

Geometry

Set Up

First, we need to specify that the geometry is 2-dimensional. Right click the Geometry box Image Removed and select Properties. This will open the Properties of Schematic A2: Geometry Window. Under Advance Geometry Options change Analysis Type from 3D to 2D.

...

After the analysis type has been set, we are ready to launch Design Modeler, the design tool in ANSYS. Open Design Modeler by double clicking the geometry box Image Removed. After launching the Design Modeler, you will be prompted to choose a standard unit of measurement. Select Meter as the standard unit, and click OK.

Sketching

We want to sketch on the XY plane. To look at the XY plane, click the positive Z-Axis on the compass in the Graphics window.

...

To begin sketching, click on the Sketching tab in the Tree Outline window. To draw our domain, we will use the Rectangle tool. Click on Image Removed in the Sketching Toolboxes window. In the graphics window, draw the rectangle by first clicking on the origin (make sure the P icon is showing, meaning you are in fact selecting the point), then select a point in the 1st quadrant.

Image Removed
Next, we need to create another rectangle, adjacent to the first. To accomplish this, we will use a 3-point triangle. Select the rectangle from 3 points tool Image Removed from the sketching tool bar. Next, select the three points specified below.
