You can do this by holding down the right-mouse button and dragging a box over the desired viewing area. Create the main pipe: Problem Specification consists of a large curved pipe accompanied by a smaller side pipe. Dragging side to side rotates the view about the vertical axis, and dragging up and down rotates the view about the horizontal axis.

For the geometry of your fluid flow analysis, you can create a geometry in ANSYS DesignModeler, or import the appropriate geometry file.
Creating the Geometry in ANSYS DesignModeler
In addition to the primitives you used in this tutorial, ANSYS DesignModeler offers a full designmodfler of 2D sketching and 3D solid modeling tools for creating arbitrary geometry. Creating the Elbow Path.
The question mark in the Geometry cell is replaced by a check mark, indicating that there is a geometry now associated with the fluid flow analysis system. Again, ensure that the selection filter is set to Facesselect the same face on the elbow to specify that the extrusion will be normal to the face and click Apply.
For the purposes of this tutorial, where you will create the geometry in inches and perform the CFD analysis using SI units, select Inch as the desired length unit and click OK to close the prompt. Click on Generate to create the side-pipe. Use the symmetry tool to reduce the model to half of the pipe assembly, thus reducing computational cost. You will probably find it helpful to rotate the view so that you can easily select the other face of the bend.
For the geometry of your fluid flow analysis, you can create a geometry in ANSYS DesignModeleror import the appropriate geometry file. Likewise, the state of some of the remaining cells in the system will change. Click on Generate to create the plane. Now select one of the end points of the arc, and then move the mouse around to the other end point and click on it to draw the quarter-circle.
They will be appended automatically because you specified the units previously.
ANSYS Workbench automatically saves the geometry and updates the Project Schematic accordingly the question mark in the Geometry cell is replaced by a check mark, indicating that there is a geometry now associated with the fluid flow analysis system.
On the Sketching tab, open the Draw toolbox and select Arc by Center to tuttorial the arc centered on the origin with a radius of 0.
Click Apply next to Symmetry Plane 1 in the Details view. Select Extrude from the 3D Features tutorkal. Sweeping requires the use of two sketches: You can also right-click the Geometry cell to display the context menu, then select New Geometry Once the geometry is defined, the state of the cell will change accordingly.
Create a anays plane based on the ZXPlane: With the new plane selected in the Tree Outlinecreate a New Sketch. In the Draw toolbox, select Line to draw two straight lines on the sketch.
Enter only the tutoriap without the units of mm. Note the Attention Required icon within the Geometry cell for the system. This specifies the direction vector from the origin to the center of the circular cross-section at the start of the torus.
Creating the Arc Profile. The grid settings that you have just set up will help you to position the arc and set its radius correctly. Likewise for the state of the remaining cells in the system.
Ensure that the selection filter is set to Faces. Extrude the faces of the torus segment to form the straight inlet and outlet lengths.
tutoriql Create the bend in the main pipe by defining a segment of a torus. Once the geometry is defined, the state of the cell will change accordingly. Elbow Main Pipe Geometry. The following table describes mouse actions that are available:. From there, you can browse your file system to locate the elbow-geometry.
