oa_database Files

oa_database Files

PRIMER looks for databases by looking for the existence of a file called 'oa_database' in the directories $ (the directory where Oasys LS-DYNA Environment is installed) and $HOME (the home directory of the user. In the instance where an 'oa_database' file is found in both these directories then the entries from both files are included.

The databases in the file from the installation directory $ are available to every user. If the file was in $HOME then the databases would only be available to that user.

Any line in the file which begins with a $ (dollar) is treated as a comment.

Each line in a 'oa_database' file refers to a database (file or directory) and contains 3 fields separated by a space, a comma or a tab character.:-

1. Database type . This indicates what type of entities are in this database. e.g. MODEL* LCUR* MATL* . The database type must end with an asterisk (*). Only databases which are relevant are displayed in each context e.g. material import will only offer MATL* databases, model build will only offer MODEL*
2. A directory or filename for MODEL* . For LCUR* and MATL* the directory contains the database information. This directory must also contain an oa_index file which explains how the info is to be used (see below)
3. A name . The database names will be used in windows when selecting a database.

An example of a 'database' file taken from an $ directory is given below containing 2 LCUR and 2 MATL databases.
