*RELEASE

17.13 *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 ro tational degrees of freedom

at one or both ends of a beam element.

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 ABAQUS Analysis User’s Manual, for the

syntax of such ﬁle names. If this param eter is omitted, it is assumed that the data follow the keyword

line.

Data lines to prescribe the released degrees of freedom:

First line:

1. Elementnum beror elem ent set label.

2. Elementend identiﬁer (S1 or S2).

3. Releasecombination code at the end of the elem ent (M1, M2, T,M 1-M2, M1-T,M2-T, ALLM).

See “Element end release,” Section 28.5.1 of the ABAQUS Analysis User’s Manual, for a

deﬁnition of the release combination codes in ABAQUS/Standard. Thisﬁeld can be left blank

if none of the rotational degrees of freedom are released at thisend of the elem ent.

Repeat this data line as often as necessary to specify the rotational degrees offreedom to be released

for different elements and elementends.
