3.4.4. nodeAccel Command

This command returns the current acceleration at a specified node.

nodeAccel $nodeTag <$dof>

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

Note

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

Example:

The following example is used to set the array/list accel1 equal to the nodal accelerations at the node given by the variable nodeTag.

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

set accel1 [nodeAccel $nodeTag]

2. Python Code

accel1 = nodeAccel(nodeTag)
