Geometry

Note

For users of ANSYS 15.0, please check this link for procedures for turning on the Auto Constraint feature before creating sketches in DesignModeler.

Import the Geometry

Please download the .igs file for the geometry here: monocoque.IGSTo Import import the geometry, right-click Geometry, go to File->Import... A dialog box will open as shown below:

To view the .igs files, go to the pull down menu to the left of the File name text box and change it to Geometry File(...). Go to the mouse-over Import Geometry and  select Browse.  Then, navigate to the location where you saved the monocoque.igs file and click Open. Your workbench should look like this:A green checkmark should now appear next to Geometry.

Build the Geometry

Double-click Geometry  to bring up Design Modeler. On the top toolbar, select Units and then choose  inch .

This particular geometry contains solids, surfaces and line bodies. In default setting, Ansys ANSYS does not build the line bodies, but we can change that with the following steps:

Double-click Geometry  to bring up Design Modeler.

Select  inch  as the unit and hit  OK .

easily. Under Detail of Import1, change Line Bodies to  to Yes  as shown below:

Now Click  Generate  to build the geometry.

This will make sure line bodies will be built along with the surfaces and solids. 

Prepare the geometry for meshing
