Creating the Geometry for the Bolted Nozzle Flange

Created using ANSYS 16.2

Learning Goals

In this tutorial, you will learn how to create the geometry used for the Bolted Nozzle Flange problem presented in Module 3 of the Cornell's Engineering Simulations MOOC on edx.org.

You can access the MOOC here:

• (e.g.: Determine the displacements and stresses in a bike crank using 3D FEA capabilities in ANSYS Mechanical)
• (e.g.: Verify the finite-element results from ANSYS by refining the mesh and also comparing with hand calculations)

Note: selecting the correct edges

Selecting the correct edges for the Blends can be hard.

For the first blend, you need to select the circular edges around the nozzle; the ones right at the corner between the nozzle itself and the flange. Check the following picture from a side view of the geometry.

For the second blend, you need to select the bottom edges inside the groove. In the picture below you can see them highlighted, but note that to ease the understanding, a "sliced" geometry is shown. Your geometry will look like this by the end of the above video!
