NODE FILE

The default value is LAST MODE=N,whereN is the num ber of modes extracted. If the

MODE param eter is used, the default value is LA ST M ODE= M,whereM is the value of the MODE

parameter.

MODE

This parameter applies only to ABAQUS/Standard analyses.

This parameter is useful only during eigenvalue extraction for natural frequencies and for

eigenvalue buckling estimation. Set this parameter equal to the ﬁrst mode number for which output

is required. The default is MO DE=1. See also the LAST MODE parameter. When performing a

FREQUENCY analysis, the normalization will follow the format set by the NORMALIZATION

parameter. Otherwise, the normalization is such that the largest displacement component in the

mode has a magnitude of 1.0.

NSET

Set this parameter equal to the name of the node set for wh ich the output is being written to the

results ﬁle. If this parameter is omitted, the output will be written for all nodes in the model.

Data lines to request nodal output in the results or selected results ﬁle:

First line:

1. Give the identifying keys for the variables to be written to the results or selected results ﬁle.

The keys are deﬁned in the “Nodal variables” section of “ABAQUS/Standard output variable

identiﬁers,” Section 4.2.1 of the ABAQUS Analysis User’s Manual, and “ABAQ US/Explicit

output variable identiﬁers,” Section 4.2.2 of the ABAQUS Analysis User’s Manual.

Repeat this data line as often as necessary to deﬁne the nodal variables to be written to the results or

selected results ﬁle.
