INCOMPATIBLE KINEMATIC CONDITIONS IN MODEL DESCRIPTION :

Kunal Hirudkar

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

          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.
