Product: ABAQUS/CAE
Benefits: Seeding can allow for the curvature of an edge. Taking the curvature into account simplifies the task of seeding models that have holes of various sizes and other regions of high curvature, such as blends.
Description: The part seeding tool allows you to specify a target element size when you are seeding a part or a part instance. If the geometry of the part is relatively regular, specifying a single target element size can result in an acceptable mesh. However, if you specify a single target element size and the geometric features that make up the part vary in size, the resulting mesh may be too coarse to adequately represent any small features, as shown in Figure 13–1.
To avoid the problem of inadequate seeding around small curved features, ABAQUS/CAE applies curvature control when it seeds a part or part instance. Curvature control allows ABAQUS/CAE to calculate the seed distribution based on the curvature of the edge along with the target element size. Figure 13–2 shows the same part seeded and meshed with curvature control enabled.
