The User’s handbook is one among 4 manuals that represent the documentation for NASTRAN, the
other 3 being the Theoretical guide, the Programmer’s handbook and the Demonstration Problem
Manual .
even if the User’s handbook comprises the entire details that's at once associated
with the answer of issues of NASTRAN, the person will locate it fascinating to consult the other
manuals for assistance within the answer of particular consumer problems.
The Theoretical handbook offers an outstanding creation to NASTRAN and offers advancements of
the analytical and numerical strategies that underlie the program.
The User’s guide is
instructive and encyclopedic in nature, yet is particular to these goods with regards to the use of
NASTRAN which are more often than not self sustaining 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 applied within the code.
The Demonstration
Problem handbook offers a dialogue of the pattern difficulties brought w! th NASTRAN, thereby
illustrating the formula of the different sorts 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 instruction manual for users.
It describes all the NASTRAN positive aspects and thoughts and
illustrates them by way of examples.
different first-class assets for NASTRAN-related themes are the
proceedings of the NASTRAN clients’ Colloquia (held quite often each year) which offer a wide body
of info in accordance with person stories with NASTRAN.
The User’s guide has lately been thoroughly revised and updated.
so that it will facilitate
easier updating of the guide sooner or later to take care of with more recent releases of NASTRAN, it has now
been divided into volumes.
Volume I involves 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
Volume II.
which will keep away from confusion, part three of quantity I doesn't include something different than
a connection with the recent quantity II.
additionally, it may be famous right here that, except explicitly indicated

that volume,
NASTRAN makes use of the finite point method of structural modeling, in which the distributed
physical homes of a constitution are represented by means of a finite variety of structural parts which
are interconnected at a finite variety of grid issues, to which quite a bit are utilized and for which
displacements are’calculated.
The systems for outlining and loading a structural version are defined in quantity I, part 1.
This part features a practical reference for each card that
is used for structural modeling.
The NASTRAN info Deck, together with the main points for every of the information playing cards, is defined in
Volume I, part 2.
This part additionally discusses the NASTRAN keep watch over playing cards which are associated
with using the program.
As pointed out prior, quantity I, part three doesn't include whatever except a reference to
Volume II.
The approaches for utilizing the NASTRAN plotting potential 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, temporary reaction, frequency reaction, modal flutter and modal aeroelastic
response analyses.
NASTRAN includes challenge resolution sequences, referred to as inflexible formats,
each one of those rigid
formats is linked to the answer of difficulties for a selected form of static or dynamic
as well as the inflexible structure approaches, the person may well decide to write his personal Direct Matrix
Abstraction application (DMAP),
This strategy allows the person to execute a sequence of matrix
operations of his selection besides any software modules or govt operations that he may well need.
The principles governing the production 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, comprises descriptions of mnemonics, acronyms, phrases,
and different wide-spread NASTRAN terms.
Volume II, part 1 incorporates a normal description of inflexible layout procedures.
instructions and knowledge for using each one inflexible structure are given in quantity II, Sections 2, 3
and four, which care for the inflexible codecs linked to the DISPLACEMENT, warmth and AERO
approaches, respectively.
There is a restricted variety of pattern difficulties incorporated within the User’s Manual.
although, a more
comprehensive set of demonstration difficulties, at the very least one for every of the inflexible codecs, is
described within the NASTRAN Demonstration challenge Manual,
the information 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 should be received via executing those demonstration
The printer output for those difficulties can also be to be had on microfiche.

Decisions with this keyword work almost identically to the decisions we have been using thus far. If the condition is met, then the code after the then keyword is executed. The else keyword signifies the end of the aforementioned code, much as the fi did previously. We now have a second block of code between the then and the fi, which is executed if the condition is not met. > if N = n then n is perfect else n is imperfect fi 6 is perfect Let’s see if there are any perfect numbers less than 6. Currently if we want to know if a number is perfect, we have two or three calculations to perform; if we were to start at n = 1 and test up until n = 6 we would end up typing out ten commands, all of which would be a little tedious.

We can clearly see that 6 is perfect (which we already knew), but we issue the if command regardless, to demonstrate the else keyword. Decisions with this keyword work almost identically to the decisions we have been using thus far. If the condition is met, then the code after the then keyword is executed. The else keyword signifies the end of the aforementioned code, much as the fi did previously. We now have a second block of code between the then and the fi, which is executed if the condition is not met.

When we calculated f (2000), above, Maple saved, and remembered, the values of the first 2000 Fibonacci numbers. So when we then went on to calculate f (4000), the first 2000 Fibonacci numbers would not have needed to be calculated again and so only 2000 more computations (f (2001) − −f (4000)) needed to be performed, and so the computation times ought to have been similar, which they were. We perform two more computations in order to better support this idea. If the above claim is correct, then we should expect that a second calculation of f (4000) should take almost no time at all, and neither should a calculation of f (4001).
