Description: The following enhancements have been added to the edge seeding procedures:

• You can now use drag-select to select multiple edges to seed.

• You can now choose double bias seeding that results in the mesh density varying from the center of the edge toward each end of the edge. Figure 12–4 shows edges of a face with single- and double-bias seeding.

  Figure 12–4 Single- and double-bias seeding.

  

• When you generated single-bias seeding with previous releases of Abaqus/CAE, you could specify only the number of elements to generate and the bias ratio. When you are applying bias seeding (single or double), you now have the option to specify the minimum and maximum element size that Abaqus/CAE should generate.

• When you are applying bias seeding (single or double), you can now reverse the direction of the bias along the selected edges.

• With previous releases of Abaqus/CAE you could apply curvature control to allow for small holes or regions of high curvature only when generating mesh seeding over an entire part or instance. You can now apply the same curvature control when you are seeding selected edges, faces, and cells.

• With previous releases of Abaqus/CAE the default seed constraint allowed the number of elements to increase or decrease. The default seed constraint now allows the number of elements to increase only.

• In addition to applying seeds to a selected set, you can now apply seeds to a selected surface.

• After you have selected the regions (edges, faces, and cells) to seed, you can save your selection in a set. If you subsequently want to change the seeding, you can select the set without having to reselect the individual edges, faces, and cells.

• If you select regions that have already been seeded with a mixture of seeding parameters, such as curvature control settings, bias selection, and constraints, you can generate seeds on the selected regions while retaining the original seeding parameters.
