Conventions#

This page summarizes the conventions used for the Z-set input files. An overview of the general command syntax (command hierarchies) is given in the beginning of the Examples/Training manual.

  • Running of Z-set modules generally requires that a “problem name” be given. Most input and output data files are based on this name with a variety of suffixes attached. Henceforth, problem will often be used to indicate the problem name given while running the commands.

  • The characters % and # indicate that the rest of the line is a comment. For example: ***load % external problem loading

  • There are no abbreviations allowed in the use of keywords. All keywords and command names must be written entirely.

  • The admissible characters for the names of user variables are: a-z, A-Z, ", +, -, *, ., =,, _, ), (, ’134, ’176/

  • The text entry is always case-sensitive.

  • The use of braces [ ] in the syntax descriptions indicates an option with a default definition.

  • All parameter values used in the input files and described as “real” in the syntax descriptions must have a decimal point. All standard specifications of floating point values are accepted. Two examples of real values are: 3.0  4.2e-5

  • The use of parenthesis () indicates data input of real values in vector form. An example is: (0.1 0.2 1.0). In most cases the size of such vectors must be compatible with the overall problem dimension.

The symbol indicates a section where the calculation is sensitive to input data or format.
