This manual describes all of the user subroutines and utility routines available in ABAQUS. The interface and requirements for each user subroutine are discussed in detail. References to practical examples of most subroutines are also provided. Utility routines can be used within user subroutines to perform a variety of common tasks. The interface for all available utility routines appears in a separate chapter. For information on incorporating a user subroutine into an ABAQUS analysis, see “User subroutines: overview,” Section 13.2.1 of the ABAQUS Analysis User's Manual.
This manual is divided into three main sections:
“ABAQUS/Standard subroutines,” Section 1.1 covers all of the user subroutines available for use in an ABAQUS/Standard analysis. Each section discusses a particular subroutine. The sections are organized alphabetically according to the subroutine name.
“ABAQUS/Explicit subroutines,” Section 1.2 covers all of the user subroutines available for use in an ABAQUS/Explicit analysis. Each section discusses a particular subroutine. The sections are organized alphabetically according to the subroutine name.
“Utility routines,” Section 2.1 covers all of the utility routines available for use in coding user subroutines. Each section discusses a task that can be performed using a utility routine. All of the utility routines associated with a particular task appear in the same section.
