then will you tell me how to make it reality with a model in inp file？

*element, type=b31,elset=component name
12345(element #), 13423(node#), 2334(node#)
*release
12345(element#),S1(s1 standing for 1st node of the beam,s2 for 2nd node),T(T for rotation along beam axis)

instead of T, you can use the other rotational DoF/combination of DoFs like below:


M1  refers to the rotation about the n1-axis,

M2 refers to the rotation about the n2-axis,

M1-M2 refers to a combination of rotational degrees of freedom about the n1-axis and the n2-axis,

T refers to the rotation about the t-axis,

M1-T refers to a combination of rotational degrees of freedom about the n1-axis and the t-axis,

M2-T refers to a combination of rotational degrees of freedom about the n2-axis and the t-axis, and

ALLM represents a combination of all the rotational degrees of freedom (i.e., M1, M2, and T).
