Tagging idea
If a project contains analytical functions only input variables (random or design) are used in functions expression. If external programs are used (i.e. metal forming FEM program) to compute some quantities used in function expressions. External variables represents those quantities (see External variables). Values of externals have to be extracted from FEM output program. To define position External variables tag window was designed. It contains:
- "variable" selection combo box,
- current file path,
- editor with selected variable tags,
- tag editing and selection panel,

To tag a variable select proper variable using "variable" selection combo box. Next ensure if proper file is loaded into editor. If not load proper file using "get file" button. Highlight place in editor where the value of selected input variable have to be placed. Press "create tag" button to create tag. Now Numpress Engine system will be able to extract value in input file. In the picture above external variable represents displacement is highlighted and it is ready for tag creation. The window contains some additional features which facilitates tag management. In selection panel user can find in editor all occurences of given text and navigate between them using ,
buttons. It contains also create and delete tag buttons together with button "Create label". Created this way label is a sort of origin on which position of variable will be determined. It is useful or even necessary where FEM output file content ( structure ) is variable and dependent on input variables value. Label must be a string in a file which allways present in the output file. If label is not created begin of file is used as origin. it is used when the structure of output file is allways the same.
