Hexa Mesh Generation for a 2D Pipe Junction In this tutorial, you will generate a mesh for a two-dimensional pipe junction comprising two inlets and one outlet. After generating an initial mesh, you will check the quality of the mesh, and refine it for a Navier-Stokes solution. Figure 1: 2D Pipe Geometry This tutorial demonstrates how to do the following: • Block the geometry. • Associate entities to the geometry. • Move vertices onto the geometry. • Apply mesh parameters. • Generate the initial mesh. • Adjust the edge distribution and refine the mesh. • Match the edges to improve quality. • Verify and save the mesh.

Hexa Mesh Generation for a 2D Pipe Junction Step 2: Associate Entities to the Geometry Step 3: Move the Vertices Step 4: Apply Mesh Parameters Step 5: Generate the Initial Mesh Step 6: Adjust the Edge Distribution and Refine the Mesh Step 7: Match the Edges to Improve Quality Step 8: Verify and Save the Mesh and Blocking Starting the Project 1. Copy the input geometry file (geometry.tin) from the ANSYS installation directory under v150/icemcfd/Samples/CFD_Tutorial_Files/2DPipeJunct to the working directory. 2. Start ANSYS ICEM CFD and open the geometry (geometry.tin). File > Geometry > Open Geometry... Note If you want ANSYS ICEM CFD to behave exactly as this tutorial describes, you should go to the Settings Menu, click Selection, and disable Auto Pick Mode in the DEZ. Most experienced ICEM CFD users prefer to enable Auto Pick Mode as it improves efficiency. See the Selection menu help for more detail. Blocking Strategy The blocking strategy for the 2D pipe geometry involves creating a T-shaped blocking and fitting it to the geometry. The 2D pipe geometry is equivalent to a T shape with the right side of the blocking crossbar bent upward to resemble the geometry. You will fit the T-shaped blocking to the geometry by creating associations between the edges of the blocks and the curves in the geometry, and then moving the vertices of the blocks onto the corners of the geometry. This procedure will be described in subsequent steps. 2 ANSYS ICEM CFD 15.0 - © SAS IP, Inc.
