ABOUT PREWAD AND WADAM

DelPieroXu

Does anyone know how to exactly define multi-body mass matrix in Prewad?  I have done the following to input the mass matrices for 3 barges (for float over operation simulation):
%%
MULTI-BODY
  STRUCTURE-IDENTIFICATION 1 100.0 0.0 -33.5 0.0 0.0 ORIGIN-OF-BODY END
  MODELS 1 PANEL-MODEL '' 1 0.0 0.0 -4.3 0.0 NONE END
  STRUCTURE-IDENTIFICATION 2 100.0 0.0 0.0 0.0 0.0 ORIGIN-OF-BODY END
  MODELS 2 PANEL-MODEL '' 2 0.0 0.0 -3.6 0.0 NONE END
  STRUCTURE-IDENTIFICATION 3 100.0 0.0 33.5 0.0 0.0 ORIGIN-OF-BODY END
  MODELS 3 PANEL-MODEL '' 3 0.0 0.0 -4.3 0.0 NONE END
END

   3 3 11 1.14380E+07 22 1.14380E+07 33 1.14380E+07 44 3.70E+08 55 2.40E+09 66 4.75E+09 END
END
     END

I did change the wadam direct solve matrix size from the 2000 default value to 12000 (because I have 3 bodies thus more panels), but WADAM does not respond to my mass input and stopped running after a while.  Is there anything wrong with the Journal code I wrote above?  Thanks alot!

Can wadam do multi-body analysis?
