Overview
Nodal adjustment is ud for:
∙ adjusting ur-specified nodal coordinates so that the nodes lie on a given surface; and
∙ 怎么用纸折小盒子specifying the direction along which the nodes are moved.
Adjusting nodal coordinates
In general, ur-specified nodal coordinates are not modified during input file processing. However, there are some situations where mesh coordinates are known only in a generic way and it is inconvenient to determine their coordinates for their actual usage. For example, when using fasteners the specified reference node should be positioned at its projection point on the associated surface. Since that location may be known only approximately, you can u nodal adjustment to move the reference node to that location automatically. For typical usage of the nodal adjustment feature, refer to “About asmbled fasteners,” Section 29.1.3 of the Abaqus/CAE Ur's Manual.
When using this feature, the nodes are adjusted to lie on the specified surface without regard for shell thickness or shell offts. Therefore, it is not advisable to u this feature as a way of correcting initial overclosures for contact or for tie constraints. In addition, car
e should be taken when choosing the nodes to be adjusted becau the feature does not respect any constraints relating the relative position of the adjusted node with other nodes (e.g., rigid body definitions).

Specifying the nodal adjustment direction
A node can be moved to the surface using a normal adjustment or a directed adjustment. By default, the node is adjusted to the clost point on the specified surface along the normal to the surface. You can specify an orientation to move the node to the surface along a given direction rather than along the normal to the surface. The vector along the local Z处女座和摩羯座配对指数-direction from the orientation definition is ud to move the node to the surface (e “Orientations,” Section 2.2.5). If no projection can be found, the nodal coordinates are left unmodified.
