*SUBMODEL
EXTERIOR TOLERANCE
Set this parameter equal to the fraction of the average element size in the global model by which a
driven node of the submodel may lie outside the region of the elements of the global model. The
default is 0.05. For shell-to-solid submodeling the driven node may lie within a region defined by
half the value of the SHELL THICKNESS parameter plus the exterior tolerance.
If both tolerance parameters are specified by the user, ABAQUS uses the tighter tolerance.
GLOBAL ELSET
Set this parameter equal to the name of the element set in the global model that will be searched
for elements whose responses will be used to drive the submodel. If this parameter is omitted,
ABAQUS will search all elements in the global model that lie in the vicinity of the submodel.
This parameter must be used with the ACOUSTIC TO STRUCTURE parameter when the
acoustic pressures act on both sides of a shell.
Data lines to define the driven boundary for general and shell-to-solid submodeling:
First line:
1. List of nodes or node set labels. Up to 16 entries are allowed per line.
Repeat this data line as often as necessary.
Data lines to define the driven boundary for acoustic-to-structure submodeling:
First line:
1. The name of the element-based structural surface.
Repeat this data line as often as necessary.
