HI @Rahul R,

I am trying a bottle simulation with radioss, I tried keeping all as simple as possible for simple test.

the file says

 .. ELEMENT BUFFER INITIALIZATION
WARNING ID :          312
 ** INCOMPATIBLE KINEMATIC CONDITIONS IN MODEL
DESCRIPTION :
    1 INCOMPATIBLE KINEMATIC CONDITIONS IN MODEL
 .. GEOMETRY PLOT FILE
 .. PARALLEL RESTART FILES GENERATION
     TERMINATION WITH WARNING
     ------------------
          0 ERROR(S)
          1 WARNING(S)
PLEASE CHECK LISTING FILE FOR FURTHER DETAILS

 

what shall I do with kinematic conditions?

    Hi,

     

    the TOP_BCS load collector constrains all DOF, which is incompatible kinematic condition with the imposed displacement in the Y translational direction on the same node of a rigid body. Therefore Y translational DOF has to be free in the TOP_BCS load collector.

    Check unit consistency: the unit system declared in the BEGIN CARD is kg, m, s however the material parameters used are consistent with tonne, mm, s.
