Product: Abaqus/Standard
Benefits: It is possible to specify local contact stabilization settings for general contact in Abaqus/Standard.
Description: Previously, contact stabilization specifications for general contact could only be made globally. An option is now provided that enables local assignments of contact stabilization for general contact. Contact stabilization improves convergence behavior for many situations, such as when small separation between some assembly components exists prior to establishing contact. Contact stabilization is not activated by default in most cases, but many analyses can benefit from its usage. When activated, numerical controls associated with contact stabilization are set quite conservatively by default such as to minimize the risk of degrading accuracy. Based on your understanding of potential unstable modes in a model, you may be able to use more aggressive settings of contact stabilization controls in certain regions to further improve performance without adversely affecting results.
