Ansys Cfx Tutorial Pdf

Select the Y-axis and then select the circle somewhere near where it intersects the Y-axis. One more operation is needed to add another straight section of pipe to the outlet.

You will need to enter all given values in the correct units of meters i. Click on Generate to create the plane. Select the rectangular face of the solid with the lowest X-coordinate to apply it to.

In Modeling Mode, the Tree View is shown, as in the picture above. This defines a set of spacing values, which can be applied to the various Controls as desired. The first part of the extension requires a Revolve operation. Using this utility, the mesh will automatically be refined in regions where the edges of the surfaces have a large curvature.

You should find that a point appears at the intersection. The type of controls available depend on the mesher used. You will use a Line Control, which refines the mesh in the region around a line. If the wrong angle is displayed just after you click on the second edge, then before you click to position the dimension right-click and choose Alternate Angle until the correct angle is displayed.

Calculating Resources Calculation Guide Lines. Click on Generate to create the extrude. You can do this by dragging a box over the desired viewing area with the right mouse button held down. When the First Layer Thickness option is enabled, the Number of Inflated Layers is used as a maximum number of layers rather than an actual number of layers. Now move the mouse button towards the top left of the Model View.

Butterfly Valve - The units after you import the Parasolid file are always meters, but the tutorial instructions expect the geometry to be in millimeters. In addition, bioinformatics by rastogi free pdf this tutorial will enable the Extended Layer Growth parameter. Spring-Mass Vibration Tutorial. This example only discusses the stifness matrix and load vector.

The basic method to do this is to create a sketch containing the three circles, and then to Extrude with Imprint Surfaces to effectively project the circles onto the full curved surface. The four faces which are required for the location are the large flat faces of the valve. Mesh Generation Notice how the nodes are concentrated around the valve. You should find that the text next to Axis now changes to Selected. The grid settings you have just set up will help you to position the circle and set its radius correctly.

For example, by changing the Display Mode you can switch to display the mesh in Wire Mesh rather than with solid faces. Click on Arc by Center from the Draw Toolbox, and click once on the origin center of the Arc shown in the picture below. Flow in a Catalytic Converter models a catalytic converter in order to determine the pressure drop and heat transfer through it. In the main part of the window, click on the existing StaticMixer project. Click on Stretch in the Tree View.

Whilst still holding down the left button, move the mouse slowly outwards towards the top left of the model view. In the popup window, select Meter as the desired length unit. Use Vertical and Radius from the Dimensions Toolbox to fix the two dimensions shown. This will give a mesh which is just one layer thick along the Z-axis, so that the flow is truly two-dimensional. You may need to rotate the model slightly to make it possible to pick all three.

The other options allow you to modify existing solids and to deal with multiple solids. Just in selecting a plotting plane and extruding a wing profile. Use Rectangle from the Draw Toolbox of the Sketching tab to draw a rectangle as shown below. You will use inflation to create layers of prismatic elements on the Wall boundaries.

In the Model View, click on the circular face at the end of the outlet pipe, which is at the position with the lowest value of the Z-coordinate. Use Circle from the Draw Toolbox of the Sketching tab to create three circles in this sketch, as shown below.

The surface mesh will be generated on just the corresponding faces. Set Type to Cut Material and Bodies to the valve. Define the Mesh Attributes. Click on Dimensions in the Sketching tab to open the Dimensions Toolbox. Set Type to Cut Material and Bodies to the blunt body.

This tutroilal is important to master becouse the user can use it to by pass learning the deisgnmodeller as long as the researcher knows how to use other modelling software. This is a large expansion factor. In particular, this means that you can use the same mouse controls to manipulate the model.

Higher values for the number of layers would give you an extruded mesh which could be used for three-dimensional flow, such as a pipe mesh with elements all aligned along the pipe direction. The picture below shows the areas of the Model View which correspond to each type of rotation. Fourier Transformation Method for a Blade Flutter Case sets up a transient blade row simulation using the Fourier Transformation model as part of blade flutter modeling. This specifies how quickly the mesh elements grow as you move away from the face.

Use Line from the Draw Toolbox of the Sketching tab to create the line. You will solve for the air flow velocity for flow over the flat plate, based on specified velocity and pressure boundary conditions, and plate dimensions. Static Mixer Symbol Meaning The item is suppressed inactive.

Right-click and select Fix Guide Line. The Extrude operation can again be used for this extrusion. As you pass over each sketch, it is selected and the edge that you passed the cursor over is highlighted. Conversions for the other values are given in the tutorial instructions.

In the Details View, right-click on the name of the profile which is in the wrong order e. Multiphase Flow in a Mixing Vessel simulates the mixing of water and air in a mixing vessel. This automatically detects dimensions which are equal and constrains them to be equal so that when one changes, the other does also. Also, the matrices could subsequently be imported to other software, if desired for some reason.

Use Polyline from the Draw Toolbox of the Sketching tab to draw the two straight lines of approx- imately the right length. Generating the Surface Mesh You will now have a look at the surface mesh to see the effect of the chosen length scale and the inflation, compared to the mesh you generated for the previous example. Now specify the exact angle as follows. The Default Preview Group always contains all faces in the geometry, so the mesh will be generated everywhere. In the Model View, click on the circular face at the end of the newly revolved pipe section, which is in the position with the lowest value of the Z-coordinate.

Why and for what reason are there some many meshing methods? Static Mixer This example shows geometry creation and meshing for a simple static mixer.

You can easily do this by selecting each sketch in the Tree View and reading the number of edges in the sketch from the Details View. Your gray lines may be in slightly different places, depending on exactly which edges you created first in the different sketches. Create a new sketch as follows.
