You can select edges, faces, or cells to seed; however, ABAQUS/CAE creates seeds only along edges. When you select faces or cells to seed, ABAQUS/CAE creates seeds only along the edges of the faces or cells. In addition, you can also select a set to seed, and ABAQUS/CAE creates seeds along the edges of the geometry contained in the set.
Figure 17–7 shows the prompt area when you start the procedure to apply seeds uniformly (by element number or by element size).
When you are applying uniform seeds, you can use a combination of the following methods to select the region to which ABAQUS/CAE will apply the seeds:Individually/By angle
You can select edges, faces, or cells individually; or you can use the angle method to select a group of edges or faces. For example, if you choose the angle method and select an edge, ABAQUS/CAE then selects every adjacent edge until the angle between the edges is equal to or exceeds the angle that you entered. For more information, see “Using the angle method to select multiple objects,” Section 6.2.3.
Selection filters
You can use filters to choose the type of object to select—Edges, Faces, Cells, or All. By default, ABAQUS/CAE allows you to select only edges. For more information, see “Filtering your selection based on the type of object,” Section 6.3.2.
Viewport/Sets
By default, ABAQUS/CAE allows you to apply seeds to edges, faces, and cells that you select from the viewport. Alternatively, you can click Sets on the right of the prompt area and select from eligible sets. When you select a set, ABAQUS/CAE applies seeds to every edge in the set, including every edge of all the cells and faces in the set. ABAQUS/CAE ignores any vertices in the set.
