Examples of Modifying the Database

PCL and Customization > Modifying the Database Using PCL > Examples of Modifying the Database

The following session file is an example of how the commands described in this chapter can be used to load analysis code specific data about a new analysis code into a Patran database.

codeindent10 1: “John Code”, a hypothetical structural analysis code

The following session file loads the open database with the analysis code definitions for “John Code”, a hypothetical and simplistic structural analysis code. This example is delivered with Patran in the $P3_HOME/customization directory under the name “load_johncode.ses.” In order to run this session file, follow these steps:

1. Within Patran, open the target database. This database can be devoid of analysis code examples, like “base.db” or can already contain analysis code definitions, like “template.db”.

2. Run the $P3_HOME/customization/load_johncode.ses session file through the “Play Session File” functionality on the main “File” menu.
