GWA Keywords


Introduction

The format of the text data file is a record by record file with fields separated by tabs or commas. Two different versions of this file can be used. The default file extension is .gwa. This reads/writes the file in an international format and is recommended where files have to be transferred between different countries. The alternative extension is .txt. This reads/writes files using the local settings for decimal points and list separators (see 'Control Panel | Regional Settings') for ease of importing the files into spreadsheets.

Each record consists of a keyword and a number of fields each separated with a tab. There may only be one record per line, but a record may be continued on more than one line. To spread a record over several lines a continuation marker (a \) should be placed in the next field position on that line. Comments can be included in the file on any line after a comment marker (an !) character. The \ should precede any comments and anything after the continuation marker will be treated as a comment. Both comments and continuation characters should be separated from the fields by a tab. Blank lines (no space or tab characters) are acceptable. A blank field is interpreted as a null string for string fields and a zero for numeric fields.

Each record is of the form:

KEY_WORD, value, value, value, value

Version numbers may be associated with GWA keywords. Versions are specified by appending the version number to the keyword, separated by a '.', for example:

NODE.2

When reading GWA records for versioned keywords, where no version is supplied the current version is assumed. GSA does not write the version to GWA records.

A new version number is assigned only when new data is inserted into an existing keyword record. New data appended to an existing keyword record does not warrant a new version number.

Where a table is referred to, this represents the following input

n, x1, y1, ... xn, yn

where n is the number of points, xi is the value of the abscissa and yi is the value of the ordinate.

The format of the specific records is as follows:

principal use principal axes
YES use principal axes of the section
NO treat the local axis as principal

Note

The base value is multiplied by the 'f' factor. If the 'f' factor is zero the base value is set to the 'i' value. So if the base value is 10 and the factor is 2 the analysis value is 20; if the base value is 10 and the increment is 12 the analysis value is 12.
