For the imported FE data types listed below, Mechanical enables you to assign custom names to reference nodes in the Worksheet. This enables you to access the nodes in the solver file (through command snippets). Your name can contain only standard English letters and numbers, spaces, underscores, hyphens, and/or parenthesis characters.
Mechanical automatically makes the following changes to your custom name in order to prepare the new reference name for the Mechanical APDL application:
A name exceeding 32 characters is truncated.
A name that begins with a number, space, hyphen, or parentheses character, is renamed to include “C_” before the character.
Spaces, hyphens, or parentheses between characters in a name are replaced with underscores.
For example, a Reference Node in the Mechanical application called "1 Edge" appears as component "C_1_Edge" in the Mechanical APDL application input file.
