Unformatted text preview: MESH COMMANDS © Fluent Inc., Jul04 31 3. MESH COMMANDS GAMBIT mesh commands allow you to specify, generate, and modify meshes and to perform operations involving mesh boundary layers. They exist in the following general subgroups: • Vertex • Edge • Face • Volume • Group • Boundary Layers • Global The following sections describe the commands available in each subgroup. Vertex Commands MESH COMMANDS 32 © Fluent Inc., Jul04 3.1 Vertex Commands GAMBIT mesh vertex commands allow you to perform mesh operations related to vertices. The command set includes the following commands: • vertex link • vertex unlink The following sections summarize the purpose, form, and parameters associated with each of the commands listed above. MESH COMMANDS Vertex Commands © Fluent Inc., Jul04 33 3.1.1 vertex link Purpose To create a hard link between two vertices. General Form vertex link vertex1 vertex2 Example vertex link "vertex.1" "vertex.2" Keywords None Vertex Commands MESH COMMANDS 34 © Fluent Inc., Jul04 3.1.2 vertex unlink Purpose To delete existing hard links associated with one or more vertices. General Form vertex unlink vertex1 [ vertex2 ... ] Example vertex unlink "vertex.4" "vertex.6" "vertex.7" Keywords None MESH COMMANDS Edge Commands © Fluent Inc., Jul04 35 3.2 Edge Commands GAMBIT mesh edge commands allow you to perform mesh operations related to edges. The command set includes the following commands: • edge link • edge mesh • edge modify • edge picklink • edge pickunlink • edge split meshnode • edge msummarize • edge unlink The following sections summarize the purpose, form, and parameters associated with each of the commands listed above. Edge Commands MESH COMMANDS 36 © Fluent Inc., Jul04 3.2.1 edge link Purpose To create a hard link between two edges. NOTE : The directions keyword on this command determines the mesh directions of the specified edges relative to their respective edge senses. For each edge, the mesh direction is either reversed or retained, relative to its edge sense, according to the value of its corresponding int specification relative to int1 . (Allowable int values include only 0 and 1.) For example, the command, edge link "edge.1" "edge.2" "edge.3" directions 0 1 0 specifies that the mesh directions of edge.2 and edge.3 are reversed and retained, respectively, relative to their respective edge senses. Similarly, the command, edge link "edge.1" "edge.2" "edge.3" directions 0 1 1 specifies that the mesh directions of edge.2 and edge.3 are both reversed relative to their respective edge senses. The actual values of the int specifications (0 or 1) do not affect the edge link operation. For example, the following two commands produce identical results: edge link "edge.1" "edge.2" "edge.3" directions 0 1 0 edge link "edge.1" "edge.2" "edge.3" directions 1 0 1 General Form edge link edge1 edge2 ......
