## Chapter 5: Autodyn User Subroutine Modules

Autodyn modules contain most of the problem variables that a user might require in order to write a user subroutine. The sections below provide a listing and description of the primary variables of interest. Note that the listing below is not inclusive of all the Autodyn modules in the program. Also, note that the modules are delivered in compiled form and therefore cannot be read as text.

Caution: The user should be very careful about changing the values contained in the standard Autodyn modules. Such actions may cause unpredictable results.
