Example: Creating the PRB data file

Here is an example of how to create a problem data file, explained step by step:

• Create and edit the file (problem_type_name.prb in this example) inside the problem_type_name directory (where all your problem type files are located). Except for the extension, the names of the file and the directory must be the same.
• Start the file with the line:

PROBLEM DATA

• Then add the following lines:

QUESTION: Unit_System#CB#(SI,CGS,User)
VALUE: SI
QUESTION: Title
VALUE: Default_title

The first question defines a combo style menu called Unit_System, which has the SI option selected by default. The second question defines a text field called Title, and its default value is Default_title.

• To end the file, add the following line:

END PROBLEM DATA

• The whole file is as follows:

PROBLEM DATA
QUESTION: Unit_System#CB#(SI,CGS,User)
VALUE: SI
QUESTION: Title
VALUE: Default_title
END PROBLEM DATA

• The options defined in the .prb file can be managed in the Problem Data window (found in the Data menu) in the Preprocessing component of GiD.
