- ELEMENT BY ELEMENT
-
Include this parameter to generate local element matrices. By default,
global assembled matrices are generated.
- ELSET
-
Use this parameter to generate matrices for a part of a model. Set this
parameter equal to the name of an element set that contains all the elements in
the selected part of a model. By default, matrices are generated for the whole
model.
- FIELD
-
Set FIELD=ALL (default) to indicate that matrices are generated for the
structural and acoustic parts of the model.
Set FIELD=MECHANICAL to indicate that matrices are generated only for the
structural part of the model.
Set FIELD=ACOUSTIC to indicate that matrices are generated only for the acoustic
part of the model.
- FRICTION DAMPING
-
Set FRICTION DAMPING=NO (default) to ignore friction-induced viscous damping effects.
Set FRICTION DAMPING=YES to include friction-induced viscous damping effects.
- MPC
-
Set MPC=YES (default) to generate the matrices with applied multipoint
constraints. The generated matrices will include entries only for the
independent degrees of freedom.
Set MPC=NO to skip applying the multipoint constraints during the matrix
generation. The matrices will include entries for all active degrees of freedom
in the model.
- PROPERTY EVALUATION
-
Set this parameter equal to the frequency at which to evaluate
frequency-dependent properties for viscoelasticity, springs, and dashpots
during the matrix generation. If this parameter is omitted,
Abaqus/Standard
will evaluate the stiffness associated with frequency-dependent springs and
dashpots at zero frequency and will not consider the stiffness contributions
from frequency-domain viscoelasticity.
- PUBLIC NODES
-
Use this parameter to specify which nodes will be visible in the matrix
usage model. Set this parameter equal to the name of the node set that contains
all the nodes that will be presented as user-defined nodes during matrix input;
all other nodes are designated as internal nodes and effectively hidden. By
default, all user-defined nodes are visible in the matrix usage model.
- SOURCE
-
Set SOURCE=ALL (default) to generate matrices including contributions from
the finite elements and from the matrix input.
Set SOURCE=ELEMENTS to generate matrices including only contributions from the
finite elements.
Set SOURCE=MATRIX INPUT to generate matrices including only contributions from the
matrix input. The ELSET and SOURCE=MATRIX INPUT parameters are mutually exclusive.
