info rotation constraint

[demaio1982]

Hello everyone I am a biomedical engineering student, I am approaching with ansys 12 apdl . I noticed that when I go to bind wrapped there is the rot displacement and wrapped up by what it depends, someone can explain it to me?! !

Rotate? xd!

Rotate? xd!

How is it not the choice of the degrees of freedom that I can bind?

 

[volaff]

You talk about the degrees of freedom of the nodes, right?

 

[stefano.garbin]

solid elements have nodes characterized by 3 degrees of freedom (positions in space): ux, uy, uz

shell elements (shells) have knots characterized by 6 degrees of freedom: positions ux, uy, uz and rx rotations, ry, rz.

because you find it on school books.

my problem is this, it is also very simple , I created a straight tilted in the x-y plane is emaciated with the link1 element in ansys 12.1 I simply wanted to bind by setting up a keypoint by binding the direction y , x and the rotation around the z axis and the other keypoint apply a force parallel to the straight . but it does not allow me to bind the rotations I tried to use the beam elements too
thanks for the help

I'm talking about nodes and keypoints, I know it's a trivial thing. Anyway I explained my problem below. I hope you can help me
