7.3.2 Extended Coupling
• MADYMO and Radioss extended coupling is available with Block Format 4.4 for Radioss
STARTER with additional functionalities.
• The following additional option is available in Radioss version 4.7:
/MADYMO/EXFEM/exfem_id/exfem_title
in which exfem_id is the FEM identification number and exfem_title is the FEM name.
Following this option, one has to specify the part id’s of the elements of which informa-
tion is exchanged with MADYMO:
1 to n CARDS:
1 2 3 ...
Ip1 Ip2 Ip3 ...
in which Ip1, Ip2, etc are the integer part id’s.
– exfem_id and exfem_title are not exchanged with MADYMO.
– Part IDs, as well as related nodes IDs and elements IDs can be used in the MADY-
MO input file, in order to define contact interfaces between these Radioss entities
and MADYMO MB or FE models. These parts must be parts of shells, 3 nodes shells
or 8 nodes bricks.
– Options /MADYMO/LINK cannot use any node belonging to these parts. Radioss
STARTER will generate an error in such a case.
– A node belonging to such a part can not be a slave node of an interface TYPE 2, nor
of a rigid body within Radioss, if it receives contact forces from MADYMO contact
interfaces: Radioss STARTER writes a warning if a node belonging to the exchanged
parts is a slave node of an interface TYPE 2 or of a rigid body.
