After generating an initial mesh, you will check the quality of the mesh, and refine it for aNavier-Stokes solution.Figure 1: 2D Pipe GeometryThis 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. Verify and save the mesh.PreparationBlocking Strategy1ANSYS ICEM CFD 14.5 -

Copy the input geometry file (geometry.tin) from the ANSYS installation directory underv145/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...NoteIf you want ANSYS ICEM CFD to behave exactly as this tutorial describes, you should go tothe Settings Menu, click Selection, and disable Auto Pick Mode in the DEZ. Most experiencedICEM CFD users prefer to enable Auto Pick Mode as it improves efficiency. See the Selectionmenu help for more detail.Blocking StrategyThe blocking strategy for the 2D pipe geometry involves creating a T-shaped blocking and fitting it tothe geometry. The 2D pipe geometry is equivalent to a T shape with the right side of the blockingcrossbar bent upward to resemble the geometry. You will fit the T-shaped blocking to the geometryby creating associations between the edges of the blocks and the curves in the geometry, and thenmoving the vertices of the blocks onto the corners of the geometry. This procedure will be describedin subsequent steps.ANSYS ICEM CFD 14.5 -

Select Numbers under Vertices.Blocking Vertices NumbersFigure 3: Initial Block(p. 4) shows the initial block enclosing the geometry. You will use the initialblock to create the topology of the model.Figure 3: Initial BlockThe curves are now colored separately instead of by part. This allows you to distinguish the indi-vidual curve entities from each other, which is necessary for some of the blocking operations. Youcan enable or disable the color coding by selecting/deselecting posite.Geometry Curves posite2. Split the initial block into sub-blocks.In this case, you will split the initial block using two vertical splits and one horizontal split.Blocking & Split Block & Split BlockANSYS ICEM CFD 14.5 -
