**add_node

Description

This command is used to enter nodes into a mesh “by hand,” and parallels the **add_element command. It is useful normally to utilize node numbers which are “far away” from those generated by other meshing commands.

Syntax

The **add_node command takes a list of node definitions as they appear in the .geof file. The node dimension will be sized according to the number of coordinates entered in after the node id. Note that zero coordinates must therefore be entered.

There is checking only if the node id already exists. No check is performed for the node coordinate.

**add_node \(~\,\) id-num \(x_2\)  \(x_2\) [ \(x_3\) ] \(~\,\) …

A duplication of this command exists which automatically creates a node set made up of the new nodes. That command has the syntax:

**add_node_nset nset-name \(~\,\) id-num \(x_1\)  \(x_2\)   [ \(x_3\) ] \(~\,\) …

Any number of nodes can be added. The entry fields are read until another **-level command is reached. The dimension of the node is assigned according to the number of entered coordinates (\(x_1\), etc above).

Example

An example use follows.

**add_node_nset some_nodes
 200 1. 0. 0.
 201 2. 0. 0.
 202 2. 1. 0.
 203 1. 1. 0.
