Select the edge that closes the loop. My advice: The criteria for the Cooper scheme are not fulfilled for the pipe. Flag for inappropriate content. To all users This creates a section through the grid that is spherical in shape.
Decomposed geometry Step 4: Journal Files 11 of 32 Shift-middle-click on a face if you need to deselect it and select the face next to it. You can view. This journal file. Journal files can be used to recreate a geometry or mesh that was created in a previous session.
You can see the journal file for the current session. Note that this step is not an essential part of the tutorial and is designed to provide information on using journal files in GAMBIT. The File Name for the current journal file will appear in the form. Edit the current journal file. If you run the journal file without executing the reset command..
In the above form. By saving the journal file to another name. Replay the steps you have taken in the current session. Note that all lines are now marked with a black box. Save the journal file with a new name. The file will be saved to your working directory. Choose the Select All option in the menu. If the Auto button is used. A second cylinder appears in the graphics window. Each time the Step button is clicked..
Each line of the journal file was displayed in the Transcript window as it was executed.. GAMBIT just used your journal file to redo the geometry creation and decomposition for the three-pipe intersection. The Auto button allows you to automatically rerun a journal file. Step 5: Turn Off Automatic Smoothing of the Mesh It is necessary to turn off smoothing of the mesh in this example to prevent the boundary layers from being smoothed out during the volume meshing.
The Step button allows you to step through a journal file one line at a time. Select the MESH tab at the top of the form. This displays the types of meshing for which you can set defaults. Enter a value of 0 in the Value text entry box. Select the FACE radio button. They are used to locally refine the mesh in the direction normal to a face or an edge. This defines the height of the first row of elements normal to the edge.
Close the Edit Defaults form.
This sets the ratio of distances between consecutive rows of elements. Step 6: Apply Boundary Layers at Walls Boundary layers are layers of elements growing out from a boundary into the domain.
Create boundary layers on the edges where the sphere octant intersects the pipes.. The direction of the boundary layer is indicated during picking with an arrow that points towards the middle of the active face or volume. Boundary layers on the three edges where the pipes intersect 17 of 32 If it is not. The boundary layers will be displayed on the edges as shown in Figure Boundary layer on three edges of the sphere octant 2.
The boundary layer will be displayed on the edge. The depth is the total height of the boundary layer. Repeat the above steps to create the same boundary layer on the three curved edges where the three pipes intersect. Shift-middle-click the edge until the arrow is pointing in the correct direction.
Mesh the Sphere Octant Volume 1. Mesh the sphere octant. The Tet Primitive scheme does not create tetrahedral mesh elements. The Tet Primitive scheme divides a logical tetrahedron into four logical-hexahedral blocks and creates hexahedral mesh elements in each block.
The mesh for the sphere octant is shown in Figure Note the boundary layers you applied on three faces of the sphere octant. In the second example. Mesh one of the pipes by changing the vertex type on the wall face to Side and then using the Cooper meshing scheme to mesh the volume. In the third example. The boundary layers will still be visible in the graphics window.
Remove the mesh from the display before you mesh the three pipes. The mesh is not deleted.. This tutorial illustrates three different ways to specify the source faces the faces whose surface meshes are to be swept through the volume to form volume elements required by the Cooper scheme.
Mesh the Pipe Volumes You will now mesh the three pipes. Mesh on sphere octant 2. This makes it easier to see the edges and faces of the geometry. In the first example.
By changing the vertex type to Side on the wall face of the pipe. The criteria for the Cooper meshing scheme will then be fulfilled for the pipe. This is the safest way to ensure correct meshing. Wall face of the first pipe volume showing the End vertex iii.
A message will appear in the Transcript window stating that the vertex was set to type Side. Select the vertex that was marked with an "E" in the graphics window where the three pipes intersect. Select Side the default under Type. The vertex will be changed to Type "S" for Side. Note the vertex on the wall face marked with an "E" for End where the three pipes intersect. Select the wall face of the pipe shown in Figure in the graphics window.
Left-click in the Vertices list box.. You will only see the vertex label if you reselect the face.
The mesh is not deleted. Select the first pipe volume in the graphics window. The pipe will be meshed as shown in Figure To remove the mesh from the display. Note that Hex Elements and the Cooper Type are automatically selected under Scheme in the Mesh Volumes form because you changed the vertex type on the wall face to Side. Pipe meshed by changing the vertex type on the wall face to Side and using the Cooper meshing scheme! It may be useful to remove the mesh from the display at this point.
Retain the default Interval size of 1 and click the Apply button at the bottom of the form.
By enforcing the Submap scheme on the wall face of the pipe. Select the wall face of the second pipe shown in Figure in the graphics window. Mesh the second pipe using the Submap scheme on the wall face of the pipe and using the Cooper meshing scheme to mesh the volume. Wall face of the second pipe volume 22 of 32 Select Off from the option menu to the right of Mesh near the bottom of the form and click Apply..
Select Quad in the Elements option menu under Scheme. Retain the default Interval size of 1 under Spacing and click the Apply button at the bottom of the form. You deselected the Mesh check box because at this point you do not want to mesh the face. Click the Apply button at the bottom of the form. Select the pipe volume in the graphics window.
Note that Hex Elements and the Cooper Type are automatically selected under Scheme in the Mesh Volumes form because you enforced the Submap scheme on the side face of the pipe. Deselect the Mesh check box under Options. Retain the default Interval size of 1. Mesh one of the pipes by hand-picking the source faces and then using the Cooper meshing tool.
When you click Apply. GAMBIT will automatically enforce the Submap scheme on the side face and modify the vertex types to honor the scheme selected.
The criteria for the Cooper scheme are not fulfilled for the pipe. Pipe meshed using the Submap scheme for the wall face of the pipe and the project scheme for the volume!
It may be useful to remove the mesh from the display at this point.. The face meshes on the three-pipe intersection are shown in Figure You can select the faces in the graphics window.
Source faces used to mesh one of the pipe volumes using the Cooper meshing scheme d Retain the default Interval size of 1 under Spacing and click the Apply button at the bottom of the form. Display all the face meshes for the three-pipe intersection. The faces are marked A through D in Figure The four faces to be selected are at opposite ends of the pipe.
Shift-middle-click on a face to deselect it and select the face next to it. You can also click Reset in the Mesh Volumes form to deselect all faces and volumes.
You will only display the face meshes at this point because displaying the volume meshes would create a cluttered view in the graphics window. This opens the Examine Mesh form.. Face meshes for the three-pipe intersection Step 9: Examine the Quality of the Mesh 1.
The "0" option displays elements on the cut. For a sphere. For the three-pipe geometry. This creates a section through the grid that is spherical in shape. The graphics window display is shown in Figure Step Set Boundary Types 1. Remove the mesh and boundary layers from the display before you set the boundary types. Spherical cut centered in the x. This restores a single window.
The spherical cut of the mesh will be removed and the face meshes will be restored. The mesh and boundary layers are not 28 of 32 Set boundary types for the three-pipe intersection.
