General Information
Detailed finite element side impact dummy models of the USSID, EUROSID and ES-2 have been developed in cooperation with the German Association for Automotive Research (FAT). The development project for the ES-2 model was launched in 2001.The major goal of the development was to achieve a high degree of accuracy of the models, followed by 'stability' criteria in order to avoid numerical instabilities. The schedule and the focus of the development for the LS-DYNA models were mainly determined by the LS-DYNA user group within the FAT. Other participants in the project were : Audi,Autoliv,BMW,Bosch,Continental,Ford,Karmann,Keiper,Recaro,Daimler, Opel, Porsche, Siemens, TRW and Volkswagen.

ES-2 Model
The development and validation has been performed on different platforms. The following LS-DYNA versions have been used:
| LS-DYNA Version | Date | Revision Nr. |
|---|---|---|
| R9.3 dm MPP | 03/13/2021 | 618 |
| R11 MPP | 06/09/2020 | 148584 |
| R12 MPP | 02/01/2022 | 3688 |
With the version 9.0 of the Euro-SID-2 50th model, the following keyword files are delivered.
