Description: The mesh sizing methods have been improved to refine the mesh aggressively in regions where the element base solution and the errors are large, allowing Abaqus/CAE to meet the specified error targets in fewer iterations. In addition, if you select the Minimum/Maximum control method, the mesh sizing has been improved to avoid overrefinement at regions where the base solution is low; the result is a better mesh with fewer elements.

For larger models in which you have specified a small error indicator target, Abaqus/CAE's remeshing algorithm may produce an unreasonably large number of elements, resulting in a prohibitively expensive analysis. You can now prevent Abaqus/CAE from creating a large number of elements by specifying an approximate maximum number of elements when you create the remeshing rule, as shown in Figure 12–2.

Figure 12–3 shows the effect of specifying the maximum number of elements in the remeshing rule. The figure shows (from left to right):

• The original mesh (approximately 14,000 elements generated).

• The mesh after a remeshing rule was applied with no limit on the maximum number of elements (approximately 450,000 elements generated).

• The mesh after a remeshing rule was applied with a limit of 50,000 elements.
