*SUBSTRUCTURE MATRIX OUTPUT

18.43 *SUBSTRUCTURE MATRIX OUTPUT: Write a substructure’s recovery matrix,

reduced stiffness matrix, mass matrix, load case vectors, and gravity load vectors

to a ﬁle.

This optionis used to write a substructure’s recovery matrix, reduced stiffness matrix, mass matrix, load case

vectors, and gravityload vectors to a ﬁle. Itcan be used only in a *SUBSTRUCTURE GENERATE analysis.

Product: ABAQUS/Standard

Type: History data

Level: This option is not supported in a model deﬁned in terms of an assembly of part i nstances.

Reference:

•“Deﬁning substructures,” Section10.1.2 of the ABAQUS Analysis User’s Manual

Optional parameters:

FILE NAME

This parameter is intended for use with OUTPUT FILE=USER DEFINE D.

Set this parameter equal to the name of the ﬁle (without an extension) to which the data will be

written. The extension .mtx will be added to the ﬁle name provided by the user; see “Input syntax

rules,” Section 1.2.1 of the ABAQUS Analysis User ’sManual, f ort he syntax of such ﬁle names.

If the OUTPUT FILE parameter is omitted or set equal to RESULTSFILE, use of the FILE

NAME parameter overrides the OUTPUT FILE setting; the data will be writtento the named ﬁle,

not to the results (.fil) ﬁle. If OUTPUT FILE=ODB, the FILE NAME parameter is ignored and

the data will be written to the outputdatabase (.odb) ﬁle.

GRAVITYLOAD

Set GRAVITY LOAD=YES to write the substructure gravity load vectors (only available if the

gravity load vectors are requestedwith the *SUBSTRUCTURE GENERATE option). The default

is GRAVITYLOAD=NO.

MASS

SetMASS=YES to write the substructure mass matrix (only available if the mass matrix is requested

with the *SUBSTRUCTURE GENERATE option). The default is MA SS=NO.

OUTPUT FILE

Set OUTPUT FILE=RESULTS FILE (default) to write the data to the results (.fil) ﬁle in the

format speciﬁed in “Results ﬁle output format,” Section 5.1.2 of the ABAQUS Analysis User’s

Manual.
