PROPERTY ATTACH Part_name [Identifier] Assignment

                                                

This command is used to assign material and physical properties to elements generated on a part, or a local coordinate system to nodes generated on a part. This command is also used to attach time curves, space curves, load masks and local coordinate systems to loads and to attach local coordinate systems to global space curves and load masks.

Part_name Identifier Assignment

ALL [MATERIAL] Material_name or NONE

Point_name [PHYSICAL] Property_name or NONE

Line_name [COORSYS] Coordinate_System_name or NONE Surface_name Body_name Set_name

Load_name [TCURVE] name or NONE

Init_cond_name [SCURVE] [LMASK] [COORDSYS]

Lmask_name [COORDSYS] name or NONE Scurve_name

The properties assigned to the geometry are transferred to the elements during translation to analysis. Note that use of a property identifier MATERIAL, PHYSICAL or COORDSYS is mandatory if the assignment NONE is used.

The local coordinate systems defined with the CONSTRUCT COORDSYS RECTANGUL, CONSTRUCT COORDSYS SPHERICAL, and CONSTRUCT COORDSYS CYLINDRIC may be attached to parts of a model requiring skewed constraints. Local coordinate systems are interpreted along with constraints and loads, where appropriate, by the interface programs.

Notes:

1.

Addition of more than one property
Material and physical properties maybe attached in the same command. The order must be material property and then physical property. The identifiers must not be used. (See Example 1).

2.

Attaching properties to lines and surfaces
There is a potential problem when properties are being attached to a model which creates both line and surface elements. When a property is attached to a set containing surfaces the property is automatically attached to the lines defining the surfaces since these are in the set also. This means that the line elements can inadvertantly be given surface properties.

This problem can be avoided by attaching the line element properties after the surface element properties have been attached.

3.

Advanced loading features
The effects of associating time curves, space curves, load masks, local coordinate systems with loads are explained in section 2.14.5.

Examples:

1.

PROPERTY ATTACH ALL MAT1 PH1

Assign material MAT1 and thickness PH1 to all elements in the model.

2.

PROPERTY ATTACH S1 SYS1

Assign local coordinate system SYS1 to surface S1.

3.

PROPERTY ATTACH B1 MATERIAL NONE

Delete the material attachment to B1

4.

PROPERTY ATTACH LO1 LM1

Attach a load mask to load LO1.

5.

PROPERTY ATTACH LO1 LM NONE

Remove a load mask attachment on load LO1.

6.

PROPERTY ATTACH LM1 CY1

Attach a local coordinate system to a global load mask.

7.

PROPERTY ATTACH SC1 CY1

Attach a local coordinate system to a global space curve.
