*SUBMODEL

18.37 *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’sManual

Optional, mutually exclusiveparameters:

ACOUSTIC TO STRUCTURE

Include this parameter if the submodel will be driven at the speciﬁe d surface by the acoustic pressure

from a global coupled acoustic-structural model.

SHELL TO SOLID

Include this parameter if a solid element submodel wil lb e driven by a global shell model. If this

parameter is included, all driven nodes must be on solid ele ments and must be located in regions

modeledwith shell elements in the global model. Ifthisparameter is included on any *SUBMODEL

option in an input ﬁle, it must be included on all *SUBMODEL options in the inp ut ﬁle.

Required parameter for SHELL TO SOLID submodeling:

SHELL THICKNESS

Ifthe OFFSET parameter is not used on the *SHELL SECTION or *SHELL GENERAL SECTION

option in the global model, set this parameter equal to the m aximum 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 use d in the model) by which a

driven node of the submodel may lie outside the region of the elements of the global mode l. If

this parameter is not used or has a value of 0.0, the EXTERIOR TOLERA NCE will apply. For

shell-to-solid submodeling the driven node may lie within a region deﬁne d by half the value of the

SHELL THICKNESS parameter plus the exterior tolerance.
