*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
–0.5 and 0.5. The offset defines the 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.
Repeat this data line as often as necessary. If the offset fraction 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. A constant 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.
