In a Nutshell

What is PCL?

? ?

PCL stands for Patran Command Language Comprehensive, fully functional computer programming language

Specifically and uniquely suited for MCAE applications Delivered as a part of MSC.Patran Versatile and easy to use

? ? ?

MSC.Patran PCL Workshop Notes 04/13/16 7/236

In a Nutshell

What can PCL be used for?

?

Integrate application or site-specific programs with the MSC.Patran user interface and database

Generate parametric/variational models for design/optimization Integrate commercial and/or in-house analysis codes with MSC.Patran

Display custom graphics Access the MSC.Patran database

Create new and/or enhanced MSC.Patran functionality Database management for analysis files Eliminate tedious, repetitive procedures

In a Nutshell

How does PCL work?

?

All MSC.Patran commands are first interpreted by the PCL command interpreter

PCL expressions are interpreted by a C program

PCL functions can be compiled into libraries (more efficient binary representation) and “linked” with a MSC.Patran session “Built-in” PCL functions are written in C or FORTRAN MSC.Patran forms and menus can be created via PCL calls to Xlib, the X-window function library

FORTRAN and C functions can be “linked” with MSC.Patran through PCL
