Manage Boundary Conditions

Create boundary conditions of any load collector type other than ACTIV using the BCs Manager tool.

Open the BCs Manager from the menu bar by clicking Tools > BCs Manager. The tool appears as a tab in the tab area.
Restriction: Only available in the Radioss user profile.

This tool combines required actions from several panels into one convenient tab interface, including the ability to create a boundary condition from both sets and individual nodes.

Create New Boundary Conditions

  1. Select the type of boundary condition you want to create in the Select type field.
  2. In the Name field, type a name for the load collector.
  3. Select the type from the drop-down menu in the Select type field.
    Based on the type selected, the options that display may change.
  4. Use the selectors to pick sets and/or individual nodes to define boundary conditions. The switch allows you change the selector to access parts, nodes, materials, properties, GRNOD (set), and GRNOD (box). Pick the type of entity to be selected from the pull down menu and click the yellow button to open the Selector panel.
  5. Enter the loading conditions in the options.
    Empty fields require user input, and yellow buttons provide links to another entity that needs to be linked; namely curve, system or sensor. Each yellow tab has two options:
    • Choose Create/select to directly create the entity from this GUI.
    • Choose Select to select an entity already defined.
  6. Click Create to create the database with the boundary condition data entered. Click Cancel to cancel the creation and Close to close the dialog.

Update Existing Boundary Conditions

  1. Highlight a boundary condition in the list to display its properties.
    This opens the Review (editing) mode of the dialog.
  2. In Review mode, every defined entity/entry in the field can replaced with new entity or modified. To replace the entity on which boundary condition is define, set the GRNOD tab to the desired entity to be selected and make the selection.
    The selection will replace the existing entity on which the BC is defined. Similarly the curve, system and sensor can be changed.
  3. The table appears with list of entities that are referred in the selected boundary condition. To edit the existing entity, select the entity, right-click it and select edit.
    This opens a corresponding panel with editing features.
    • Click Update to update the changes made to the selected boundary condition. Click return to go back to Create mode.
    • Click Cancel to nullify all updates made to the selected boundary condition. Click return to go back to Create mode.
    • Click Close to nullify all updates to the selected boundary condition and close the dialog.
    • Click Review to highlight the entities on which the selected boundary condition is defined.
