In order to add a new analysis code to Patran three steps must be performed. First, modify the database to contain data about the new analysis code. This is done through PCL function calls. The resulting database will possess the information needed to display the new analysis code on the analysis preferences form. The preferences form allows the creation of element property, material property, loads and boundary condition, and multi-point constraint forms specific to the new analysis code. Also, element verification parameters specific to the new analysis code can be employed. This first step is fully described in Modifying the Database Using PCL.

Second, specific PCL functions to control the Analysis forms used for the new analysis code must be created. These routines will be used to create a PCL library which will be brought into Patran automatically when the analysis preference is set to the new analysis code. These forms can be as simple or as complex as desired. Creation of these Analysis forms is described in detail in Creating New Analysis Forms Using PCL.

Third, a translator must be created to import and export data to and from the Patran database. The functions used to extract, add or evaluate data stored in a database are discussed in the final two chapters. Accessing the Patran Database (Ch. 8) describes the standard Patran database interface, and PATRAN 2.5 Database Compatibility (Ch. 9) discusses database functions which are compatible with PATRAN 2.5.
