The Define Boundary on: Nodes or geometry option allows you to define various types of boundaries on individual nodes or geometry.  Boundaries created on nodes have a special graphical display in Engineering Solutions.  Loads created on geometric entities like surfaces, lines or points are automatically mapped to FEA mesh on export.  You can also map them using the Map Loads on Geometry button.

The Define tab for Define Boundary on: Nodes or geometry has the following buttons:

Define from 'Constraints' panels

Opens the Constraints panel to create/update boundary conditions.

To create a boundary on nodes, go to the create subpanel, select the nodes button, pick the desired nodes from Engineering Solutions graphics, check the constrained degrees of freedoms, and click create.

To create a boundary on geometry, go to the create subpanel, select surfs, points, or lines using the switch, pick the desired geometry from the graphics, check the constrained degrees of freedom, and click create.

Notes:

•Loads created on geometric entities are automatically mapped to FEA mesh on export. You can also map them using the Map Loads on Geometry button.
•An existing boundary can be updated from the update subpanel.
•While you are in the constraints panel, press the h key to view panel-specific help.
•When you are finished creating or updating boundary conditions, click return to update Step Manager with the new loads.

Map Loads on Geometry

Opens the loads on geom panel to map loads on geometry to FEA mesh entities.

Click Map loads to map all geometric loads in the current load collector to FEA entities.

Note:

•You can also pick other load collectors by clicking the loadcols button and map loads in all of them together.
•While you are in the loads on geom panel, press the h key to view panel-specific help.
•When you are finished, click return to update Step Manager with the new loads.
