### 2.3.7. LS-Dyna

There are three ways to exchange an ACP composite model with LS-Dyna:

- Workbench 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.
