PRIMER 22.1

Dealing with Character Labels in Older Output Formats

Various problems can arise when writing keyword decks for versions of Ansys LS-DYNA prior to LS971 R7.1

Problem	Solution in PRIMER
Character labels have been used for *PART, but this is not supported in the chosen format.	Each such part is automatically given a new and unique numeric label in the keyword output deck so that this is readable. The character label of the part inside PRIMER is not changed.
Character labels >8 characters wide have been used for PART, and referred to by ELEMENT cards, but use of regular format means that the data fields on the *ELEMENT cards are only 8 columns wide.	From 971 R7.1 onwards the relevant *ELEMENT cards will be written in long output format, designated by appending a "+" to the end of the keyword header line for the elements. Output formats prior to 971 R7.1 will adopt the "replace character label with unique numeric label" strategy as described above.
Character labels >10 characters wide have been used, but the chosen output format is regular, meaning that only 10 column wide data fields are available.	This will be detected by the normal pre-output model checks, and the user will be warned and presented with a range of options. The correct solution is to swap to long format, making 20 wide data fields available; alternatively the character labels can be edited manually to reduce their width to 10 characters or less. However if the user continues with regular format output then any character labels wider than the field width available will be replaced by a unique new label as described above.
