This will send data from surface /2/1 to LS-DYNA. In LS-DYNA one may refer to this data
using reference 1. Note the arbitrary value 0.0 for EXTERNAL_DATA, which is not used in
LS-DYNA.

Verification
The user is advised to check the log file and the reprint file to verify if all entities are commu-
nicated correctly. The LS-DYNA log file shows the LS-DYNA output of all entities received
from MADYMO, the reprint file shows the entities MADYMO sends to LS-DYNA.
The LS-DYNA log file:
MADYMO3D external number = 1.00000E+00
MADYMO3D coupling flag............ = 2.00000E+00
More information below these lines is printed in the LS-DYNA log file concerning the FE mesh
builds on top of the ellipsoid. All of this information should be checked.

5.3.2 Extended Coupling
The coupling with LS-DYNA supports triangular and quadrilateral shell elements (*ELEMENT_-
SHELL), hexagonal solid elements (*ELEMENT_SOLID) and thick shell elements (*ELEMENT_-
TSHELL).
