off these features should be used with extreme caution.
Session termination
The current pro-STAR session is terminated by choosing File > Quit from the menu bar. This displays the Quit pro-STAR dialog box shown below, reminding you to save the results of the session to a .mdl file (in case this has not already been done explicitly). Alternatively, you may deliberately exit from pro-STAR without saving the present session’s work, by clicking Quit, Nosave.
Set Manipulation
pro-STAR has extensive facilities for collecting and modifying sets of objects.
These are accessible by clicking one of the coloured buttons down the left-hand side of the main window. The pro-STAR entities serviced by the buttons are:
• C-> — cell sets
• V-> — vertex sets
• S-> — spline sets
• Bk-> — mesh block sets
• B-> — boundary sets
• Cp-> — couple sets
• D-> — droplet sets
Each button offers a wide range of possibilities to select, delete or re-select sets. For example, selection may be done by picking all objects falling within a given geometric range in a local coordinate system. Using other criteria, one can collect together all cells or boundaries connected to the current vertex set (and the reverse).
Selection can also take place by simply using the screen cursor to point to items on the current plot.
Each button gives direct access to the following set manipulation options:
• All — select the entire set
• None — empty out the current set
• Invert — invert the current set, i.e. select all entities that are not currently selected and un-select the ones that are
• New — replace the current set with a new set, formed on the basis of a criterion given in a secondary drop-down list
• Add — add more members to the current set, selected using one of the criteria in the secondary drop-down list
• Unselect — remove some members from the current set, selected using one
Command: QUIT
Set Manipulation
of the criteria in the secondary drop-down list
• Subset — select a smaller group of members from those in the current set, selected using one of the criteria in the secondary drop-down list
In addition, C-> offers one extra option, Surface, which selects all cells lying on the surface of the most recent mesh plot and makes them the current set. Further details on the above set selection options are given inChapter 2of the Meshing User Guide, for each of the mesh entities described there.
Note that it is possible to save and restore useful cell, vertex, spline, block, boundary and couple sets without the need to rebuild them frequently. This is done by clicking the INFO button at the left-hand side of the main pro-STAR window.
The following operations are possible:
1. To perform a ‘save set’ operation, select INFO > Store Set/Surface/View and then click the Sets tab to display the dialog shown below:
The input required is as follows:
(a) Set File — The name of the set (.set) file that will store the set definition. If such a file already exists, pro-STAR’s built-in file browser may be used to help locate it.
(b) Name — An identifier for the set being saved, up to 80 characters long Click Write to save the set definition.
2. To delete a set definition previously stored, use the same dialog as above and specify the following information:
(a) Set File — The name of the set (.set) file containing the definition to be deleted. pro-STAR’s built-in file browser may be used to locate it.
(b) Select Entry — The location of the set to be deleted, as select from the list.
Click Delete to delete the set definition.
3. To perform a ‘restore set’ operation, select INFO > Recall Set/Surface/View Commands: SETWRITE SETDELETE

and then click the Sets tab to display the dialog shown overleaf:
The input required is as follows:
(a) Set File — The name of the set (.set) file containing the set definition.
pro-STAR’s built-in file browser may be used to help locate it
(b) Select Entry — Select the particular set required by name from the scroll list. The status of the selected entry is displayed in the box underneath (c) Choose Data — Specify the type of set to be read in (All, Cells, Vertices,
etc.) by clicking one of the displayed option buttons
(d) Read Option — Specify how the sets to be read in will modify any existing sets by selecting one of the menu options (Newset, Add, Unselect or Subset)
Click Recall to recall the selected set.
Note that it is possible to print a summary of all data sets stored so far by typing command FSTAT.
Selecting sets of various entities has two major uses:
1. To display only items in the currently active set. For example, each time Cell plot is chosen from the Plot menu, pro-STAR plots only cells in the currently active cell set. Note that command SETADD causes all newly-defined cells to be automatically added to the current set. Thus, successive plots of the current state of the mesh can be made without needing to build a new set after each new cell definition. SETADD may also be used in the same way for other kinds of sets, i.e. boundaries, cell couples and splines.
2. To perform almost any modelling or post-processing operation on the Command: SETREAD
