Two other Mechanical APDL commands, NSVR and /UCMD, can help you implement UPFs. (Neither command has an equivalent GUI path.) Use the NSVR command to define the number of extra variables that need to be saved for user-programmable element options, such as user plasticity.

Issue the /UCMD command to make a user routine into a custom command. For more information, see Defining Your Own Commands.
