ERROR

ERROR

(OP)
Hello,
I'dont know what shall I do when this message of error appears:
THIS DEGREE OF FREEDOM HAS BOTH DISPLACEMENT AND VELOCITY SPECIFIED. THIS IS NOT ALLOWED;
I  have applied rotation and velocity in the reference point and it doesn't work.
thanks                          

RE: ERROR

Re-read your physics books then look at it again.

RE: ERROR

(OP)
Really, I don't understand what do you mean by re-read your physics books:in fact I try to do an existing example of the
rolling proccess and it doesn't work.
Thanks

RE: ERROR

It makes no physical sense to apply a prescribed displacement AND a prescribed velocity to the same degree of freedom in an FE analysis.  

RE: ERROR

Apply rotational and translational values of velocity and it should work. Of course you could apply a displacement (either translational or rotational) over a fixed time period and you'll have your velocity.
