I/O Options EntryThe INFILE command is used in the I/O Options section to identify the file containing the Bulk Data Entries.


INFILE = option


Argument Option Description
option <file prefix>

Default = passed in from the command line.

file prefix
The path to and prefix of the .fem file containing the Bulk Data Entries.


  1. This card is used in the obsolete two-file setup; the one-file or multiple-file setups are recommended (see Bulk Data Input File for more information).
  2. Prefixes specified on the INFILE card can be arbitrary file prefixes with optional paths appropriate to the operating system (Windows or Unix). They may be enclosed in quotes (double or single quotes can be used), and either forward slash (/) or back slash (\) characters can be used to separate parts of the path name. The following rules are used to locate a file referenced on the INFILE card: When the argument contains the absolute path of the file (if it starts with "/" on Unix or a drive letter, such as "D:", on Windows, for example), the file at the given location is used. When only the file prefix is given (without the path), the file has to be located in the same directory as the file containing the INFILE command. When the argument contains a relative path (../filename or sub/filename, for example), it is located in the directory relative to the file containing the INFILE command and is not relative to the directory in which the solver was executed, or to the directory where the main file is located.
  3. The total length of information on this card is limited to 200 characters (including the card name and spaces between arguments). This data can be on a single line or span multiple continuation lines. See I/O Options and Subcase Information Entries Guidelines for an example showing how to enter long file names on multiple lines.
