Keyword Editing

Purpose:

Every LS-DYNA keyword card can be created, viewed, modified, and deleted as part of model building process using this interface via the fuctions found on Keyword manager.

This description is the same as in the LS-DYNA Keyword Manual. Except for extended remarks, most information from the keyword manual is available in LS-PrePost for easy reference.

For each card type, a list of sub-types is presented as sub-tree items of it. Each sub-type can be edited. Upon editing a sub-type, a keyword form is presented in a separate pop-up window consisting of a list of that particular of data type.

Selecting one of the keyword items on Keyword manager will expand and show all sub-keywords of this group, double click to launch the keyword editing window for a specific keyword.
