*SUBMODEL

EXTERIOR TOLERANCE

Set this parameter equal to the fraction of theaverage elem entsize in the global model by which a

driven node of the submodel may lie outside the region ofthe elem entsof the global model. The

default is 0.05. For shell-to-so lid 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 ofthe 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-solidsubmodeling:

First line:

1. Listof node s 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-structuresubmodeling:

First line:

1. Thename of the element-based structural surface.

Repeat this data line as often as necessary.
