problem with discret element DIS_TR

Posted by Albert Montolio Aguado at October 29. 2015

Hi everyone,

 

 I have problems with a DIS_TR element which I called 'hinge'.

 

_F(

      GROUP_MA=('hinge',),PHENOMENE='MECANIQUE',

      MODELISATION='DIS_TR',

),

 

I defined the properties of the element this way:

 

 

_F(

      GROUP_MA=('hinge',),

      CARA='K_TR_D_L',

      VALE=(1e6,1e6,1e6,0,1e9,1e9,),

      REPERE='GLOBAL',

    ),

 

and keep receiving the

following message;

I don't see the mistake in my command file unfortunately.  I think it has to do with the connection between a DIS_TR and a DIS_T.  I attach the file .mess, just in case anyone could help me. I would appreciate any kind of hints.

Thanks a lot.

Albert
