Chapter 1: Understanding User-Programmable Features (UPFs)

The Mechanical APDL program has an open architecture, allowing you to write your own routines or subroutines in C, C++, or Fortran and either link them to the program or use them as external commands. Some standard program features originated as user customizations, also known as user-programmable features (UPFs).

You can take advantage of user customization if you are licensed for the Ansys Mechanical Enterprise family of products (Ansys Mechanical Enterprise, Ansys Mechanical Enterprise PrepPost, and Ansys Mechanical Enterprise Solver).

Other Ansys, Inc. products do not support customization of the Mechanical APDL program.
