PRESENT GRAPH NODE Nodes

          

This command will produce a graph showing the variation of results at a specified node across the range of loadcases specified in the RESULTS LOADCASE command. If more than one node is specified then graphs for each (up to a limit of 1000) will be superimposed. The required nodes can be an OLD list (the last node or nodes to be graphed), they can be specified as part of the command, or they can be taken from a specified set (see note 1).

Notes:

1.

Specifying a set
If a set is specified that is an element set, then the nodes used in the graph will be all those nodes that define the elements in the set.

2.

Element results
This command is only available if the currently selected results attribute contains nodal results. If element results have been selected then a warning message will be produced and the user should use the command PRESENT GRAPH ELEMENT.

3.

Graphs of more than one attribute
The results graphed will be the currently selected results superimposed with any results previously added to the RESULTS STACK. In this way multiple attribute graphs are possible, provided of course that all of the attributes to be graphed are nodal results.

4.

Input of results data to FEMVIEW
For a time, frequency, or load step related loadcase, the results should be submitted to FEMVIEW in ascending order of time, frequency, or load step within the loadcase.

5.

Graphs across static loadcases
If a range of static loadcases has been specified with the RESULTS LOADCASE command, then the graph will be plotted with a constant increment along the x-axis.

6.

Graphs of nodal material dependent results
Where the results values are nodal material dependent, the required material may be specified with the RESULTS RANGE MATERIAL command. If no material number is specified then all of the materials encountered will be used.

7.

Graphs of results for multiple surfaces
Where there are results values for more than one surface, the required surface or surfaces may be specified with the RESULTS RANGE SURFACE command. If no surface number is specified then all of the surfaces encountered will be used.

Examples:

1.

PRESENT GRAPH NODE OLD

A graph of the currently selected results and those previously stored in the results stack at the previously selected node(s) against loadcases is drawn.

2.

PRESENT GRAPH NODE 1 TO 10

A graph of results at the specified nodes against loadcases is drawn.

3.

PRESENT GRAPH NODE bracket

A graph of results at the nodes in the set `bracket' against loadcases is drawn.
