| 00:01 | Hello and welcome to the spoken tutorial on Creating and meshing a Curved-Pipe Geometry in Salome for OpenFOAM. |
| 00:10 | In this tutorial, we will see:
|
| 00:23 | To record this tutorial, I am using:
|
| 00:35 | To practice this tutorial, the learner should have Salome installed on his computer. If not, you may refer to the tutorial on Downloading and Installing Salome. |
| 00:51 | Open Salome software by clicking on the Salome icon on the desktop. |
| 00:57 | Click on the Geometry module in the Modules bar |
| 01:00 | and click on New. |
| 01:03 | Let's click on New Entity in the top menu bar. |
| 01:06 | In the drop down options, go to Basic and then 2d sketch. |
| 01:12 | First Point is zero zero, by default. Press Apply. In front of 'Y', type 30 |
| 01:22 | and click on Apply. Now, go to second Element Type Arcs. |
| 01:26 | Select Type as Direction and Direction as Tangent. |
| 01:32 | Type the Radius as -10 (minus ten) and the Angle as 90. Press Apply. Now select the Element Type Lines. |
| 01:43 | Select the Type as Direction and Direction as Tangent. |
| 01:47 | Type the length as 30. Press Apply and Close. |
| 01:54 | Let me zoom in for the closer view. |
| 01:58 | Open the Geometry tree in the Object Browser. We can see sketch_1. |
| 02:04 | You can check off to hide the sketch and check on to see it back. |
| 02:09 | Now, go to New Entity >> Blocks >> Divided Disk. |
| 02:16 | Select the orientation as OZX and type the Radius equal to 1. |
| 02:21 | Click on Apply and Close. Now, go to New Entity >> Generation >> Extrusion Along Path. |
| 02:31 | Select the Base Object as Divided Disk_1 and Path Object as Sketch_1 from Geometry tree. |
| 02:38 | Click on Apply and Close. We see Pipe_1 has been created. |
| 02:45 | Now, go to New Entity >> Explode. Select the Main Object as Pipe_1. In the Sub-shapes Type drop down menu, select Face. Check on Select sub-shapes. |
| 03:03 | Let me move this window. Let me zoom-in by scrolling up. I can rotate the object by clicking on this Rotation menu. |
| 03:16 | Hold the left mouse button and move the mouse upwards to rotate the object. Take the mouse pointer at the place shown on the screen. |
| 03:28 | Hold the left mouse button. |
| 03:30 | Drag the mouse so that all the inlet faces fall into the rectangular area. |
| 03:37 | Release the mouse button. |
| 03:41 | Now, click on Show only selected button to ensure that all the inlet faces have been selected. |
| 03:49 | Click on Apply and Close. We see five faces have been Exploded in the geometry tree. |
| 03:58 | Now, click on New Entity >> Group >> Create. |
| 04:05 | Select the Main shape as Pipe_1 from the geometry tree. |
| 04:11 | Select the Shape Type as Face. |
| 04:16 | Now, select the five faces from the geometry tree. Add them by clicking on this Add button. Name the group as inlet. |
| 04:30 | Click on Apply and close. We see inlet group has been created. |
| 04:38 | Follow the similar procedure on the other end of the pipe and group those faces as outlet. |
| 04:45 | I have created outlet face group. Now, to mesh the object, go to Modules drop-down menu, select Mesh. |
| 04:57 | Now, in the top menu bar, click on Mesh >> Create Mesh. |
| 05:04 | Select the Geometry as Pipe_1 from the Geometry tree. |
| 05:09 | Click on Assign a set of hypotheses button . Click on 3D: Automatic Hexahedralization. |
| 05:20 | Type the Number of Segments 12. |
| 05:23 | Click on OK. Click on Apply and Close. We see Mesh_1 in the Geometry tree. |
| 05:32 | Right-click on it. Click onCompute. Close the window. |
| 05:40 | We see Mesh has been created. |
| 05:43 | Let me Zoom-in. |
| 05:45 | I can move the object by this panning option. |
| 05:51 | Now, we will refine the mesh in the flow direction. |
| 05:56 | To do so, go back to the geometry module from Modules drop-down menu. |
| 06:03 | Now, let me get the proper view by using panning and rotation option. Let me zoom-out. |
| 06:15 | Go to New Entity >> Explode. |
| 06:20 | Select the Main Object as Pipe_1. |
| 06:24 | Sub-shapes Type, Edge. |
| 06:29 | Check on Select sub-shapes. |
| 06:34 | Let me move the window to the corner. |
| 06:37 | Now, take the mouse pointer as shown on the screen. Hold the left mouse button. |
| 06:43 | Drag the mouse so that all the outlet face edges fall inside the window. |
| 06:50 | Release the left mouse button. The selected edges are seen in white color. |
| 06:57 | click on hide selected Similarly, there are 3 more face edges that we need to select one by one and hide. |
| 07:14 | After that, you would only see the edges in the flow direction.Let me zoom out move the object. |
| 07:25 | Select all of these edges using similar method and click on Apply and Close. |
| 07:33 | In the geometry tree below outlet we see 24 edges have been exploded. |
| 07:40 | To group these edges go to New Entity>>Group>>Create. |
| 07:46 | Select the Shape Type as Edge. |
| 07:50 | Select the Main Shape as Pipe_1 from the geometry tree. |
| 07:56 | Now, select all of these edges and click on Add button.' to add this edges. |
| 08:04 | Name the group as flowedges. Click on Apply and close. |
| 08:11 | We see, flowedges group has been' created. |
| 08:17 | Now Go to Mesh module from modules drop down option. |
| 08:22 | Right click on Mesh_1 and click on Create Sub-mesh. |
| 08:28 | Select the geometry as flowedges. |
| 08:33 | 'Select the algorithm, wire discretization. |
| 08:37 | Now, to select the appropriate hypothesis click on first button to the right of the drop down menu. |
| 08:47 | Click on, Nb. Segments. |
| 08:50 | Type the number of segment as 30. |
| 08:54 | Click on Ok. Click on Apply and Close. |
| 09:00 | Now, click on Mesh_1 ' click on Compute. Refined mesh has been created. Close the window. |
| 09:12 | We see mesh has been refined in the flow direction. |
| 09:18 | To save this work,Go to File>> Save As Type the File name' as Curved-geometry. |
| 09:28 | I am saving this work on the Desktop. Save minimize Salome. |
| 09:37 | We see file has been saved as Curved-geometry.hdf. |
| 09:43 | In this tutorial we have learned:
To create curved pipe geometry in Salome. To mesh the geometry in Salome. To modify the mesh using submesh. |
| 09:55 | For Assignment,
Create a pipe having inner diameter 6 units smaller than the outer diameter. Change the angle of the bent. |
