$ TITLE
NAME
where the relevant control parameters for the coupling with MADYMO are
– IDMDBO, i.e. the FE deformable body identification number
– CTYPE, i.e. the FE mesh type (SHELL, SOLID or NODE)
– BULK, i.e. the average bulk modulus to be used by MADYMO.
– THICK, i.e. the average thickness to be used by MADYMO.
– IDCVS, i.e. external identifier to be referenced in MADYMO.
– Every MDBODY card is followed by cards to define element or node selection by
keywords (See General Entity Selection sub-section in the CONTROL SECTION of
the PAM CRASH/SAFE manual)
• The "COUPLING MADYMO" keyword is mandatory in the control section.
• This card should be repeated for each FE Deformable Body to be sent to MADYMO.
• If the average bulk modulus and/or the average thickness are not defined, average val-
ues will be computed by PAM CRASH/SAFE.
• The identifiers IDCVS, set in the MDBODY cards, can be referred to in the MADYMO
input deck as part id’s.
• If MDBODY type equals NODE, the IDCVS label can not be used in MADYMO. Instead,
one must refer to the individual node numbers. Note that element and part information
related to the communicated nodes is not send to MADYMO.

PART 1
END
This forces PAM CRASH/SAFE to send all shell elements belonging to part 1 to MADYMO.
Average bulk modulus and thickness are calculated by PAM CRASH/SAFE. In MADYMO the
elements can be referred to either by element number or by the reference number 3(!).
