3.1.3. node Command

This command is used to construct a Node object. It assigns coordinates and masses to the Node object. The assignment of mass is optional.

node $nodeTag [ndm $coords] <-mass [ndf $massValues]>

Argument	Type	Description
$nodeTag	integer	unique tag identifying node
$coords	list float	ndm nodal coordinates
$massValues	list float	optional ndf nodal mass values

Example:

The following examples demonstrate the commands in a script to add two nodes to domain in which the last model command specified an ndm of 2 and a ndf of 3. The two nodes to be added have node tags 3 and 4. Node 3 is located at coordinates (168.0, 144.0) and node 4 at location (168.0,144.0). Node 4 is assigned a mass of (10.0, 10.0, 0.).

1. Tcl Code

node 3 168.0 0.0
node 4 168.0 144.0 -mass 10.0 10.0 0.0

2. Python Code

node(3, 168.0,  0.0)
node(4, 168.0,  0.0, '-mass', 10.0 10.0 0.0)
