Hi forum, 

 

I'm doing a crash analysis of a motorcycle and I would like to assign MAT/LAW13 (RIGID) to the engine (shell elements). I'm also using a RBODY with master node in the centre of gravity of engine to add mass to the model. 

The solver gives me this error: 

 

** ERROR TRAPPED : REPORT TO LISTING FILE
ERROR ID :          760

 

This error doesn't apppear if I use MAT1 for shell elements of the engine.

Where is the problem?

    Kindly check the element collector is asssigned as parts and proper material and elemental property. Make sure you assign rigids under rbody or none.

    HI,

     

    Looks like a compatibility problem,

     

    /MAT/RIGID is not compatible with kinematic condition or with Advanced Mass Scaling (/AMS), but it is compatible with /BCS.
     
    /MAT/RIGID is not compatible with /PLOAD, /CLOAD, /GRAV, /IMPDISP, /IMPVEL, /IMPACC, /IMPTEMP, /INIVEL and /INITEMP. If loading is used, it is recommended to use /RBODY, instead of /MAT/RIGID.
