Input Files

Concyl reads all of the required model data from a specially formatted input file. This model input file can include comments to make it easier to read and edit manually, if desired. Any line beginning with an exclamation point is treated as a comment line, and any text following an exclamation point is treated as comment text. This input file is used by Concyl for non-GUI runs as well as GUI runs. The GUI automatically generates a temporary input file and reads it whenever a new solution is computed. The input file format is described below.

The first line of the input file is the header record which must begin with the text string, "!Concyl". The table below provides the input file format. Several of the lines have lists of values. All lists must have the individual values separated by commas. The radius list (record 5) can be split onto several lines, if desired, to make the file easier to read. This is done by putting a continuation character (ampersand) at the end of each line that will be continued onto the next line. The sample input file below shows how the radius list can be split.

Table 4 below shows the required input file format. The input file format consists of three sections: (1) the main section with a list of required parameters to define the materials, cylinders, and applied loads, (2) an optional section that specifies the desired solution quantities to be written to the Excel plot file, and (3) an optional section that specifies the input parameters for the built-in optimizer module. If the plot section is missing, then all possible solution quantities are written to the plot file. If the optimizer section is missing then a single run is done. If the optimizer section is present then a series of runs will be done to vary the specified input parameter through a series of values. Section 3 requires the presence of Section 2. So the input file can have the following combinations of sections: 1, 12, or 123.
