niloo-ga,
I have found the following companies that may be able to help you out.
Note that I do not necessarily recommend any of them to you, this is
simply a list. These companies do not use MSC/Nastran "exclusively",
but they do have it available (the listings are in no particular
order).
FEA Consulting of Long Beach, CA:
http://www.feaconsulting.com/index.htm
American Consulting Service of South Dakota
http://www.iw.net/~acs_fea/MAIN.HTM
Analysis Pros of Woodland Hills, CA
http://www.analysispros.com/
Optimal, Inc. Novi, MI
http://www.optimalinc.com/
The following link may also be of some help to you. This is a list of
FEA consulting companies from the Open Directory Project:
http://dmoz.org/Business/Industrial_Goods_and_Services/Engineering/Consultants/Analysis/
I hope this information answers your question to your satisfaction.
If not, please request additional information.
Best Regards,
krobert-ga |

Of the four companies listed FEA is too large and extremely expensive.
I have written to American Consulting Services and AnalysisPros for
rates and greater details. The dmoz directory is too large and too
generalized.
From the Directory of Associations I have found THE ASSOCIATION OF
SMALL RESEARCH, ENGINEERING AND TECHNICAL SERVICE COMPANIES of
BALTIMORE, MD but had no luck in either finding a telephone number or
web site. Members of this Association should be, I believe, would be
ideal for me.
I need to add another criterion to narrow the search. I am looking
only for engineering analysis using MSC.Nastran

I am searching for the association mentioned, but I need a
clarification from you.
You say that you need engineering analysis using only MSC.Nastran, but
you also comment that "Of the four companies listed FEA is too large
and extremely expensive". Are you referring to their rates, or are you
referring to their analysis capabilities? Are you perhaps looking for
a simpler solution that MSC.Nastran?
Best Regards,

I have confirmed from a former member that the "Association of
Small Research, Engineering and Technical Service Companies" is most
likely now defunct.

niloo-ga,
Based on your additional clarification, I have located two other
companies that may be able to fulfill your need:
1) CSM Software
http://www.csmsoftware.com/
They are a small company headquarted in India, with branch offices in
the USA (New Jersey and Los Angeles). They seem to use MSC products
almost exclusively.
Secondly,
2) CSEI
http://www.cseinc.org/
Which also does analysis using MSC/Nastran. They are located in
Wilsonville, Oregon.
As stated before, I do not necessarily recommend either company to
you.
Hope this helps,

This is in response to your comment on 5th Nov 12:03 PST When I say
too expensive I mean the rates. When I say too large I mean the
Corporation looked to me to be at least medium sized with medium
annual turn over. I will check out out csmsoftware and cseinc as
suggested.
I will today checkout with the publishers of Directory of Associations
about the Association of Small etc.
Thank you for your patience.
REGARDS

That was my understanding of what you meant... I just wanted to be
sure. There are plenty of small (read: tiny) firms out there that can
do structural analysis... just not necessarily with MSC.Nastran (or
visualNastran). I didn't specifically look for any, but I would
imagine that there are plenty of people out there that can do
freelance work in structural analysis.
It may be worthwhile to look for a university student that can do this
for you, depending on the level of professionalism that you are
looking for. This would involve looking for a university that teaches
using MSC.Nastran and then locating a student who is doing, say,
graduate work utilizing FEA structural analysis. Someone like that
may be able to get this done for you quickly and on the cheap... but,
you probably won't have the thoroughness that a firm can provide...
ergo, the rates that you see. If this may work I can find some
universities for you.
Best Regards,

I am not necessarily looking for on the cheap. I am expecting a
professional job for I am involved in a serious difference of opinion
about "SIGN CONVENTIONS" specifically with Dr. V. K. Kaliakin,
Associate Professor of Civil Engineering, University of Delaware and
generally with al professional engineers about interpreting signed
output.
If you have a mechanical or Civil engineering background you would
understand it, for it plays a very crucial role in our student and
professional career.
It was by sheer good luck that I found the ARCHON ENGINEERING
COMPANY of very modest charges. They were using ALGOR software - an
excellent and perfectly accurate tool. The problem I encountered, and
I am assuming you have a an engineering background, was that their
report on bending moment consisted of two oppositely signed values at
top and bottom of the plate. Bending Moment as most students and
professional engineers consider is a single signed value at the middle
point of the plate. I begged ARCHON to convert the two oppositely
signed values to a single one - but I could not convince them.

Sorry about just reposting your comment... I got a little trigger
happy on the "post clarification" button.
I haven't done a lot of structural analysis lately, but I could add
that depending on how a beam is loaded and depending how thick it is
(or how high it is, if you prefer), the bending moment could vary
quite a bit along it's thickness.
This makes for an interesting mind game though. For a plate (to use
your construct) to have, say, a positive moment at the top (the plate
dips and holds water) and a negative moment at the bottom (the plate
rises and rejects water)... you'd almost have to be stretching it by
pulling it from it's outer edges.
Like I said, I haven't done SA in a while, so take the above with a
grain of salt.
I think this answer is getting a little off track of the original
question though, so I'm going to bow out now.
