Editing an LS-DYNA Model to Add Cards not Supported
Even though most LS-DYNA cards used by the majority of users are supported, some cards are not. In order to use unsupported cards with the LS-DYNA model, you can add them in HyperMesh (no need to use a text editor). Select unsupp_cards in the Control Cards panel. You can then enter the cards in the pop-up text editor. You should exercise caution regarding formatting and card validity. Care should also be taken if any of the cards point to entities (such as cards pointing to sets, parts, and so on). These cards are stored as text and pointers are not considered. When importing an LS-DYNA mode, any cards that are encountered that are not supported are written in this section, thus they are exported along with the remaining model.
Blanks
In the card editor, all the attribute fields are supported as Blanks. You must click the field and input the value.
