Hard Points—Topology Optimization
Click Home and then click the arrow next to Control. Click Hard Point. The Hard Point Control dialog box opens. Use this control to define a datum point as a hard point. If you define a point this way, the mesh generator treats it as part of the mesh, creating nodes and defining elements accordingly.
Specify the following information in the dialog box:
• Name—Specify a name for the control or use the default name.
• References—Select one or more points, a feature of points, or a pattern of points so that the mesh generator can use it to place an element node or nodes. You can select the valid geometry before or after opening the Hard Point Control dialog box. The References collector shows your selections.
• Node ID—Specify the node ID. This option is available only when you select a single point. When the mesh is complete, the number replaces the node ID for the selected hard point. You can define a hard point without specifying a node ID.
