*SUBMODEL

*SUBMODEL:

Specify driven boundary nodes in submodeling analysis.

This option is used to specify the total list of “driven nodes” for a submodel.

Products:

ABAQUS/Standard

ABAQUS/Explicit

Type:

Model data

Level:

Part, Part instance, Assembly

Reference:

“Submodeling,” Section 10.2.1 of the ABAQUS Analysis User’s Manual

Optional, mutually exclusive parameters:

ACOUSTIC TO STRUCTURE

Include this parameter if the submodel will be driven at the specified surface by the acoustic pressure
from a global coupled acoustic-structural model.

SHELL TO SOLID

Include this parameter if a solid element submodel will be driven by a global shell model. If this
parameter is included, all driven nodes must be on solid elements and must be located in regions
modeled with shell elements in the global model. If this parameter is included on any *SUBMODEL
option in an input file, it must be included on all *SUBMODEL options in the input file.

Required parameter for SHELL TO SOLID submodeling:

SHELL THICKNESS

If the OFFSET parameter is not used on the *SHELL SECTION or *SHELL GENERAL SECTION
option in the global model, set this parameter equal to the maximum value of the shell thickness in
the global model (given in the units used in the model). If the OFFSET parameter is used in the
global model, set this parameter equal to twice the maximum distance from the reference surface
to the top or bottom shell surface.

Optional parameters:

ABSOLUTE EXTERIOR TOLERANCE

Set this parameter equal to the absolute value (given in the units used in the model) by which a
driven node of the submodel may lie outside the region of the elements of the global model. If
this parameter is not used or has a value of 0.0, the EXTERIOR TOLERANCE will apply. 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.
