RESULTS STACK ADD/IMPORT-XY/CLEAR

        

This command allows up to five different results selections to be stored in a `RESULTS STACK'. Initially the results stack is empty. When a results type, attribute, component and optionally a calculation has been selected the command RESULTS STACK ADD may be used to add this to the results stack. Then subsequent selections of results type, attribute, component and optionally calculation may be specified, and these may in turn be added to the results stack as well. Results selections identical to any already in the results stack can not be added to the stack again, and the results stack may be cleared with the command RESULTS STACK CLEAR.

Currently the results stack is only referenced when a graph is being plotted, when graphs for the currently selected results will be superimposed with any in the results stack. For other results presentation modes only one results selection (the current one) is used.

The results stack can also be used to select external files of X and Y values to be superimposed on a graph. The command RESULTS STACK IMPORT-XY filename may be used to specify a file whose name and path is then stored. When a graph is subsequently drawn data will be read from the file and superimposed on the graph as if the results in the external file were results for an attribute and component. Up to five external files may be stored in the results stack, which are removed with the command RESULTS STACK CLEAR.

The first line of each external file is for the Y-axis label. Only the first 20 characters are used and this line can be left blank if desired. Each subsequent line should contain an X value and a Y value, and optionally a point identification number and/or a 1 or 0 to indicate whether the point should be joined to the previous point (=1) or not (=0). These lines have a free format, and values can be separated with spaces, commas, semi-colons or colons. Any other non-numerical characters will be ignored. However values for only one point should appear on each line and they should be in the correct order. If no point identification number is given then by default the points are numbered in sequence. If no value is given to indicate whether or not a point is to be joined to the previous one then by default the point will be joined. To enter this value without having to enter a point identification number two separators can be entered between the Y value and this value.

A typical sequence of commands

Let the results stack be empty at this point.

  RESULTS NODAL STRESS S11

The results stack is still empty at this point.

  RESULTS STACK ADD

The results stack now contains the results `NODAL STRESS S11'.

  RESULTS NODAL STRESS S33
  RESULTS NODAL STRESS S22
  RESULTS STACK ADD

The results `NODAL STRESS S22' are added to the stack but the results `NODAL STRESS S33' are not.

  RESULTS ELEMENT STRAIN E11
  RESULTS STACK ADD
  RESULTS ELEMENT STRAIN E22
  RESULTS STACK ADD

The results stack now contains the results `NODAL STRESS S11', `NODAL STRESS S22', `ELEMENT STRAIN E11' and `ELEMENT STRAIN E22'. Any graph plotted now would have lines for each of these results attributes superimposed. If any other method of presentation was used now then the results `ELEMENT STRAIN E22' (the current results) would be displayed.

  RESULTS NODAL STRESS S11
  RESULTS STACK ADD

These results are not added to the results stack because they already have been. The results stack remains unchanged.

  RESULTS STACK CLEAR

The results stack is now empty again.
