RELEASE: Release rotational degrees of freedom at one or both ends of a beam
element.
This option is used to release a rotational degree of freedom or a combination of rotational degrees of freedom
at one or both ends of a beam elem ent.
Product: ABAQUS/Standard
Type: Model data
Level: Part, Part instance

Optional parameter:
INPUT
Set this parameter equal to the name of the alternate input file containing the data lines for this
option. See “Input syntax rules,” Section 1.2.1 of the ABAQ US Analysis User’s Manual, for the
syntax of such file names. If this parameter is omitt ed, it is assumed that the data follow the key word
line.
Data lines to prescribe the released degrees of freedom:
First line:
1. Element number or element set label.
2. Element end identifier (S1 or S2).
3. Release combination code attheend of theelement (M1, M2, T,M1-M2, M1-T, M2-T, ALLM).
See “Element end release,” Section 28.5.1 of the ABAQUS Analysis U ser’s Manual, for a
definition of the release combination code s in ABAQUS/Standard. This field can be le ft blank
if none of the rotational degrees of freedom are released at this end of the element.
Repeat this data line as often as necessar y to specify the rotational degrees of freedom to be released
for different elements and element ends.
