3.4.3. nodeVel Command

This command returns the current velocity at a specified node.

nodeVel $nodeTag <$dof>

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

Note

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

Example:

The following example is used to set the variable vel1 to the nodal velocity at node given by the variable nodeTag in the 1 degree-of-freedom direction.

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

set vel1 [nodeVel $nodeTag 1]

2. Python Code

vel1 = nodeVel(nodeTag,1)
