There are three ways to exchange an ACP composite model with LS-Dyna:
LS-DYNA (Extension Library): This approach allows you to convert a Workbench model, including Composite Definitions, to an LS-Dyna model. This is the recommended approach.
LS-Dyna Interface (ACP Add-on): Allows you to define Composite Definitions for LS-Dyna meshes/models.
LS-Dyna Solid Model (ACP Add-on): Allows you to export to the solid model in the .K file format.
Caution: The add-on features described in this section are not recommended for general use. It is strongly suggested that you use the Workbench interface to transfer information between ACP and LS-Dyna.
