The Define tab allows you to define *BOUNDARY cards on individual nodes or geometry (surfaces, points, lines). You can also define the boundary on node sets. There are five different types of boundary conditions available:

It is recommended that you use only one boundary type per load collector in Engineering Solutions. If you need to use multiple boundary types in the same STEP, define each type in a separate load collector and add them to the same load step.

You can define a *BOUNDARY card on nodes/geometry or on node sets.  For Define Boundary on:, the following options are available:

 

The layout of the Define tab changes, based on your selection.
