Two-Way Radio User Manual

SUBMODEL

EXTERIOR TOLERANCE

Set this parameter equal to the fraction of the average elem ent size in the global m odel by which a

driven node of the subm odel 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 m ay 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, ABAQU S uses the tighter tolerance.

GLOBAL ELSET

Set this parameter equal to the nam e of the element set in the global model that will be searched

for elements whose responses will be used to drive the subm odel. 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 s et labels. Up to 16 entries are allowed pe r 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.
