error

error

(OP)
Hi Dears
I want to create a moment at a node but when did this, the job analysis aborted due to errors. the Error is:
"1 nodes have inactive dof on which boundary conditions are specified. The nodes have been identified in node set ErrNodeBCInactiveDof."
what can I do?

RE: error

It looks as if you are applying a moment to a node which does not have a rotational degree of freedom. What element type is involved (is your node part off). Solid elements have only translational degrees of freedom so you cannot apply moments to the nodes.

thank bkal
but waht should i do now ,should i change my element type ? which type works for this matter ?
also the area that i put moment , have rotational degree of freedom.
thanks

RE: error

Can you explain more what type of structure / component are you modelling and what element types do you have at the moment.

RE: error

The issue with your model is that you are using 3d solid elements which do not have rotational degrees of freedom, so you cannot apply a moment directly. How to go about it depends very much of what you are trying to model (i.e. real physical situation) and what are you interested in. From the CAE file it is not clear at all what the modelled component is, the moment is applied to a single node on the surface of a solid cylinder; and I da not know what aspects of the results you are interested in. I would suggest that you talk with somebody more senior / experienced in your organisation to get some guidance.
