PROPERTY BOUNDARY RELEASE [name] part dof

    

This command is used to release fixed single point constraints in terms of translations and rotations. The command has the same effect as using the command PROPERTY BOUNDARY CONSTRAINT with negative degrees of freedom. The degree of freedom names listed below are the defaults; these may be changed via the FEMGV resource file (see the Installation and Customisation Guide).

name = constraint name for use in future references.

part = the name of a point, line, surface, body, or set.

dof = released degree of freedom.

1 or X = x-translation

2 or Y = y-translation

3 or Z = z-translation

4 or RX = x-rotation

5 or RY = y-rotation

6 or RZ = z-rotation

XSYMM = x-translation, y,z-rotations

YSYMM = y-translation, x,z-rotations

ZSYMM = z-translation, x,y-rotations

ALL = x,y,z-translations, x,y,z-rotations

XASYMM = x-rotation, y,z-translations

YASYMM = y-rotation, x,z-translations

ZASYMM = z-rotation, x,y-translations

ENCASTRE = x,y,z-translations, x,y,z-rotations

PINNED = x,y,z-translations

NOROTATE = x,y,z-rotations

Notes:

1.

Degree of freedom indicator
The degree of freedom may be input as text or an integer. More than one degree of freedom may be referenced at any time. In integer syntax any integer which is a combination of at most five of the digits 1-6 is a valid constraint. In text format a list of degree of freedom names may be entered delimited by spaces or a degree of freedom macro (e.g. XSYMM) may be entered.
