3.4.2. nodeDisp Command

This command returns the current displacement at a specified node.

nodeDisp $nodeTag <$dof>

Argument	Type	Description
$nodeTag	integer	tag identifying node whose displacements are sought
$dof	integer	optional: specific dof at the node (1 through ndf)

Note

If optional $dof is not provided, an array containing all displacement components for every dof at the node is returned.

Example:

The following example is used to set the variable disp1 to the nodal displacement at node given by the variable nodeTag in the 1 degree-of-freedom direction.

1. Tcl Code (note use of set and [ ])

set disp1 [nodeDisp $nodeTag 1]

2. Python Code

disp1 = nodeDisp(nodeTag,1)
