Introduction This tutorial will guide you through the creation of a simple parallel plate mesh, and how to export that mesh into a CFX readable format. Geometry Nomenclature The following image shows the basic geometry of the parallel plates. As such, our final geometry looks like a narrow box. Figure 1: Parallel Plate Channel Geometry. Creation of geometry 1. Create parts from surfaces 3. Create a block and associate the created geometry 4. Allocate nodal distribution along the block edges 5.
Mesh the block 6. Create the file needed for input in CFX Pre. Setup It is highly recommended that you create a new directory to work in. Several files will be created and it is much easier to find them later if they are all in a new directory. The last line of the above set of commands gives the path and current directory names; simply ensure there are no spaces. Note that throughout the tutorial, unless directed to use the right or middle mouse buttons explicitly, all commands are to be performed using the left mouse button.
Your screen should look like like this:. Some general names for different parts of the ICEM window will be used to help identify where certain commands are found.
The different parts are named the main menu, main buttons, option tabs, options buttons, sidebar, model tree, and view window. These are all labelled in the following image. The new sidebar 'Create Point' is opened. You will see the point in the centre of your screen and you can now observe the 'Name' field is updated.
Repeat the above steps for the following 7 points: pnt. Recall that we have defined the position of these points times larger than the geometry dictates 0.
We will scale this down by when we create the CFX readable file our very last step. In order to see all of the points you can use the main menu's 'View' options. When you are ready, press 'Fit Window' from the main buttons and select 'Isometric' from 'View' in the main menu. Your screen should now look like this:. You will now see the names above the points in your view window. Select 'File' from the main menu, and then select 'Save Project As'.
In the future, save frequently by pressing 'Save Project' in the main buttons. Leave the 'Name' at its default of 'crv. Note that it may be difficult to select the points from the current view because the points are very close together, but you cannot pan or zoom with the mouse normally because you are in selection mode.
In order to leave the selection mode press F9 on your keyboard, and then use the mouse controls normally. Once you have adjusted the current view simply press F9 on your keyboard again to return to selection mode. Leave the 'Name' at its default of 'srf. Leave the 'Method' and 'Tolerance' at their default values of 'From Curves' and 0. As with the creation of curves you can modify your view while in selection mode by pressing F9 on your keyboard, using the mouse-view controls normally, and then pressing F9 again.
Notice that there are several point names over top of one another so that the names are illegible. The new sidebar 'Create Body' is opened. Leave the default setting of 'Centroid of 2 points' in the 'Location' choice. Note that the way we defined this body it is in the centre of the domain and that any two, opposite vertices could have been chosen with the same final result.
Also, the 'By Topology' option in the 'Create Body' sidebar could have been chosen and either the entire model, or all of the surfaces used to define the body in the centre. When you use the 'Fit Window' and 'Isometric' view options you should have the following:.
To do this we will create new parts. In the geometry tree right click the word 'Parts' and select 'Create Part' from the menu that appears. The new sidebar 'Create Part' is opened.
Repeat this process for the other five surfaces with the following names: srf. You may now turn off surface names in the model tree. The new sidebar 'Create Block' is opened. Leave the 'Type' field as its default '3D Bounding Box'. Press the middle mouse button and then press 'Apply' in the sidebar. Press 'Dismiss' in the sidebar. In the model tree, you should now have a new branch named 'Blocking'. You should see the following after pressing 'Fit Window' and choosing 'Isometric' from 'View' in the main menu:.
The new sidebar 'Blocking Associations' is opened. You should see the white lines turn green:. For more complicated geometries, manual association must be performed. At this point, turn on 'Curves' and also turn curve names on once again in the geometry tree.
The new sidebar 'Pre-Mesh Params' is opened. This time select crv. Again, press 'Apply' and ticks will appear on all the lines in the y- direction. Again, press 'Apply' and ticks will appear on all the lines in the x- direction. Wait a moment while the mesh is generated. When you zoom in there will be a grid around the geometry. To do this, select 'Output' from the option tabs. The sidebar 'Solver Setup' is opened.
Highlight 'Yes' in the 'Scaling' field and set the x-, y- , and z-scaling factors to 0. Note the scaling is necessary because we input dimensions times greater than those dictated by the geometry.

Components from and simplification different formats can easily be combined within one meshing session. Flexible geometry support, combined with our very geometry-tolerant meshers, can reduce or eliminate the need for CAD repair or NURBS surfacing of faceted geometries. Meshing Capabilities ANSYS ICEM CFD software includes surface-patch 4Robust algorithms for creating a wide independent mesh methods for generating shell, tetrahedral variety of mesh types: hexa, tetra, prism, pyramid, quad, tri or bar elements linear or hexahedral meshes. Patch independence allows the user or quadratic for use with a range of to selectively capture important geometric features, yet physics and solvers ignore flaws such as slivers or gaps. These meshers can walk 4Extended, parametric and persistent over significant defects in the geometry without requiring it mesh controls can be applied to be repaired. The blocking is scriptable and parametric and can be associated with topologically similar geometries, saving work on successive models and empowering simulation to lead design. In addition to comprehensive mesh checks, it offers a wide variety of 4Check mesh, wide variety of metrics, quality metrics and other tools for mesh diagnosis and repair.
