Auxiliary Actions with Boundary Conditions

Auxiliary actions with boundary conditions include:

delete;
list output;
graphical display;
highlight.

Deleting

The removal of boundary conditions is carried out as follows:

On the Command Bar, select Mode - Boundary Conditions.
Select Entity - Displacement, Entity - Force or other boundary condition subject to deletion.
Select Action - Delete.
In the input window ID, specify the ID of the deleted the boundary condition.
Click Apply.

The following commands serve the same purpose:

delete {bc_type} [<ID-range> | all]

delete boundary conditions

Possible values of the bc_type parameter (types of boundary conditions) are given in table 1 of subsection Boundary conditions. Undo (command undo) in relation to deletion boundary conditions do not apply.

Using the delete boundary conditions command, it is possible to simultaneously delete all boundary conditions and their sets.

List output

To output a list of boundary conditions, do the following:

On the Command Bar, select Mode - Boundary Conditions.
Select as Entity the desired type of boundary conditions.
Select Action - List.
In the input window ID, specify the ID of the boundary conditions.
Click Apply.

Appropriate output command options:

list {bc_type} [<ID-range>]

list boundary conditions

The meaning and possible values of the bc_type parameter are specified higher. When interpreting the first version of the command , the program can recognize boundary conditions for the geometric entity on which they are imposed. For example, when entering the command list pressure in surface 1 a list of all pressures acting on the surface 1 will be displayed.

Using the second option of the command, a list of all boundary conditions and their sets is displayed. The list contains the total number of boundary conditions of each type and the number of their sets.

Graphical display

To graphically display the boundary conditions, you should:

Select the Mode on the Command Bar - Boundary Conditions.
Select the desired type of boundary conditions as Entity.
Select Action - Draw.
In the input window ID specify the ID of the boundary conditions.
Select Draw (pressed by default).
Click Apply.

These actions correspond to the command:

draw {bc_type} {<ID-range> | all} [add]

When entering a command, the graphical window is cleared with the removal of all parts of the model, except those selected for displaying boundary conditions. The add keyword allows you to display multiple boundary conditions simultaneously.

Selection

To highlight certain boundary conditions in the graphical window, it is necessary:

Select the Mode on the Command Bar - Boundary Conditions.
Select the desired type of boundary conditions as Entity.
Select Action - Draw.
In the input window ID specify the ID of the boundary conditions.
Select Highlight.
Click Apply.

Selection Command:

highlight {bc_type} {<ID-range> | all}

The boundary conditions are highlighted in bright orange, and the arrows, corresponding to vector quantities, thicken. The described command is similar to the draw command.
