The User’s handbook is one in every of 4 manuals that represent the documentation for NASTRAN, the
other 3 being the Theoretical guide, the Programmer’s guide and the Demonstration Problem
even if the User’s handbook includes all the details that's without delay associated
with the answer of issues of NASTRAN, the consumer will locate it fascinating to consult the other
manuals for suggestions within the resolution of particular person problems.
The Theoretical handbook provides a great advent to NASTRAN and offers advancements of
the analytical and numerical methods that underlie the program.
The User’s handbook is
instructive and encyclopedic in nature, yet is specific to these goods on the topic of the use of
NASTRAN which are in general self reliant of the computing method being used.
topics and data that's required for the upkeep and amendment of this system are
treated within the Programmer’s Manual.
The Programmer’s guide additionally offers an entire description
of this system, together with the mathematical equations carried out within the code.
Problem guide provides a dialogue of the pattern difficulties introduced w!th NASTRAN, thereby
illustrating the formula of the differing kinds of prob’!emsthat can b~ solved with NASH?PN.
In addition to the 4 guide~ defined above, there's additionally a NASTRAN User’s consultant that
serves as a guide for users.
It describes the entire NASTRAN positive factors and concepts and
illustrates them by means of examples.
different first-class assets for NASTRAN-related subject matters are the
proceedings of the NASTRAN clients’ Colloquia (held mostly each year) which supply a wide body
of details in keeping with person stories with NASTRAN.
The User’s handbook has lately been thoroughly revised and updated.
with a purpose to facilitate
easier updating of the guide sooner or later to maintain with more recent releases of NASTRAN, it has now
been divided into volumes.
Volume I comprises seven sections dIldcontains the entire fabric that was once within the old
single quantity, other than part 3.
This part has been re-arranged into 4 sections and forms
for you to keep away from confusion, part three of quantity I doesn't comprise something different than
a connection with the recent quantity II.
additionally, it's going to be famous right here that, except explicitly indicated
to .... sections

NASTRAN makes use of the finite point method of structural modeling, in which the distributed
physical homes of a constitution are represented by way of a finite variety of structural parts which
are interconnected at a finite variety of grid issues, to which so much are utilized and for which
The systems for outlining and loading a structural version are defined in quantity I, part 1.
This part includes a sensible reference for each card that
is used for structural modeling.
The NASTRAN info Deck, together with the main points for every of the knowledge playing cards, is defined in
Volume I, part 2.
This part additionally discusses the NASTRAN regulate playing cards which are associated
with using the program.
As pointed out previous, quantity I, part three doesn't comprise whatever except a reference to
The tactics for utilizing the NASTRAN plotting strength are defined in quantity I, part 4.
Both deformed and undeformed plots of the structural version are available.
reaction curves are also
available for static, brief reaction, frequency reaction, modal flutter and modal aeroelastic
NASTRAN includes challenge answer sequences, known as inflexible formats,
each one of those rigid
formats is linked to the answer of difficulties for a specific kind of static or dynamic
as well as the inflexible structure approaches, the person may possibly decide to write his personal Direct Matrix
Abstraction application (DMAP),
This strategy allows the consumer to execute a sequence of matrix
operations of his selection in addition to any application modules or government operations that he may possibly need.
The ideas governing the construction of DMAP courses are defined in quantity I, part 5.
The NASTRAN diagnostic messages are documented and defined in quantity I, part 6.
NASTRAN Dictionary, in quantity I, part 7, includes descriptions of mnemonics, acronyms, phrases,
and different widespread NASTRAN terms.
Volume II, part 1 incorporates a common description of inflexible layout procedures.
instructions and knowledge for using every one inflexible layout are given in quantity II, Sections 2, 3
and four, which take care of the inflexible codecs linked to the DISPLACEMENT, warmth and AERO
There is a restricted variety of pattern difficulties integrated within the User’s Manual.
besides the fact that, a more
comprehensive set of demonstration difficulties, no less than one for every of the inflexible codecs, is
described within the NASTRAN Demonstration challenge Manual,
the knowledge decks can be found on tape for
each of the pc platforms on which NASTRAN has been implemented.
Samples of the printer output
and of constitution plots and reaction plots might be acquired by means of executing those demonstration
The printer output for those difficulties is additionally on hand on microfiche.
