*SURFACE PROPERTY ASSIGNMENT

Data lines for PROPERTY=OFFSET FRACTION:

First line:

1. Surface name. If the surface name is omitted, a default surface that encompasses the entire

general contact domain is assumed. Faces speciﬁed on elements other than shell elements,

membrane elements, rigid elements, and surface elements will be ignored.

2. The“word” ORIGINAL (default), the “word” SPOS, the “word” SNEG, or a value between

–0.5and 0.5. Theoffset deﬁnesthe distance (as a fraction of the thickness) from the midsurface

to the reference surface (containing the nodes of the element). Positive values of the offset

are in the positive element normal direction. The default is ORIGINAL, which indicates that

the offset speciﬁed in element section deﬁnitions (via the OFFSET parameter on *SHELL

SECTION or *RIGID BODY) will be used.

Repeatthis data line as often as necessary. Ifthe offsetfraction assignments overlap, the last assignment

applies in the overlap region.

Data lines for PROPERTY=THICKNESS:

First line:

1. Surface name. If the surface name is omitted, a default surface that encompasses the entire

general contact domain is assumed.

2. The “word” ORIGINAL (default), the “word” THINNING, or a scalar value representing a

nominal thickness.

3. Aconstant scaling factor (default is 1.0).

Repeat this data line as often as necessary. If the thickness assignments overlap, the last assignment

applies in the overlap region.
