INPUT

Set this parameter equal to the name of the alternate input file containing the data lines for this option. See Input Syntax Rules for the syntax of such file names. If this parameter is omitted, it is assumed that the data follow the keyword 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 at the end of the element (M1, M2, T, M1-M2, M1-T, M2-T, ALLM). See Element End Release for a definition of the release combination codes in Abaqus/Standard. This field can be left blank if none of the rotational degrees of freedom are released at this end of the element.

Repeat this data line as often as necessary to specify the rotational degrees of freedom to be released for different elements and element ends.
