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 select a set or surface to seed; as a result, Abaqus/CAE creates seeds along the edges of the geometry contained in the set or surface.
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 and feature edge 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 all types of object. The option to select by angle becomes available only after you select Edges or Faces from the selection filters. For more information, see “Filtering your selection based on the type of object,” Section 6.3.2.
Sets or surfaces
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/Surfaces on the right of the prompt area and select from eligible sets (or surfaces). When you select a set (or surface), Abaqus/CAE applies seeds to every edge in the set (or surface), including every edge of all the cells and faces. Abaqus/CAE ignores any vertices in the set (or surface).
