Are there any public domain or commercial finite element codes that do
nonlinear geometric and material problems with p-finite elements, like
PROBE does for linear elasticity?  If not, what is considered the best
nonlinear code available?  What are the capabilities of said code?

The system equation is [K]{x} = {F} with perhaps a few added terms here
and there. Since you've solved for {x}, and you can form or retrieve
[K], you _should_ be able to do the matrix multiply.

OK, that's the theory.  Now the ANSYS experts can jump in and tell you
how to access [K] & {x}...

a) what happened to the top 3 schools (I assume Georgia Tech is really #7)?
b) is it any wonder that the person who posted this list actually goes
to one of the schools in the top 10?

I think this thread has been discussed in many a newsgroup before (i.e., the
top ten for ANYTHING), but is all this stuff of any importance to us?  We've
all seen the statistics, and we all (hell, we're reading this newsgroup :-) )
should realize the futility of such lists, especially when culled from
such a magazine as Newsweek.  If you like small schools, will these (mostly
big) schools make you a better engineer?  Learning engineering (or anything
else for that matter) has a lot to do with environment and other factors
which I'm sure can't be put in a neat little list.

I've met 'top ten' school people before (and not just in engineering) who
are bozos, and 'top ten' people who are brilliant.  Furthermore, I'm not
complaining that my school didn't make the list- my friends at MIT (I would
assume this to be in the 1-3 slots) tell me that it's sometimes no great
 shakes there either (i.e., he works in a room without windows too).  

Let's leave the lists to the fuzzy wuzzy humanities types.

The place I used to get these is also out-of-business now--maybe this

In any case, I hear from some Russian sources that are local that
there's a store in Rockville, MD (Washington, DC suburbs) called
  Victor Kamkin, 4956 Boiling Brook Pkwy in Rockville

only some of Victor Kamkin's books are translated to English

have gotten more expensive since Russia went capatalistic. :-(

i

I work in h-p adaptivity andcurrently use an executable frontal solver 
routine ( based on Hood's algorithm ) to solve my systems of equations. Does
any of you know of any public domain or shareware frontal solver which allows
multiple degrees of freedom at each element node ? I am willing to pay for 
it ( if necessary ). The inclusion of source code is optional. However, there
should be some documentation on the variable names used so that I can call 
the solver routine correctly from within my FEM code. A fortran or C module
of the solver is preferred. Instead of buying outside packages, I had to 
develop most of my p - version FEM software for my research. But, very recently
I came to know that there are a few programs like MARC which allow 
implementation of new element types, and a choice of frontal solvers with 
multi-dof at nodes. Does any of you have any clue on this kind of capabilities
for commercial softwares ? Any tip from faithful MARC users will be 
appreciated. Please email me at ::    "abose@oread.cc.ukans.edu"

Hello, my project group is having a tough time getting relevant information thatwill help us design a pressure regulator for a natural-gas operated vehicle. Thepressure regulator we have in mind should received an input pressure of 3600 psiand reduced it to about 80 psi. The output flow rate is variable. 

If you know where to get hold of a book that can help us design the regulator,  please let us know as soon as you can. Thanks in advance !!

Hello,

I help teach a PE review course intended for engineers taking the FE  
(formerly the EIT) examination.  Being an EE, I review electromagnetics,
circuit theory, etc.  I am always wanting to improve these lectures so
I would like to hear from engineers (especially non-EEs) regarding their 
FE/EIT preparation and success with respect to electrical topics. 
Specifically:
(1) What electrical/electronics topic(s) were most troublesome?
(2) What references proved most helpful in working electrical problems?
(3) Assuming you might have attended a review class - what would you like 
(or have liked) to see in such electrical review lectures?
Please feel free to add any other comments.  Note: I do *not* want specifics 
regarding actual exam problems just general information.  Thanks in advance 
for your help.  Future students may appreciate it:)

Cheers,
Kevin

Excuse me,
I have a problem. In a masters class of mine I require a text book on

Groundwater Hydrology" by Bower and was published in 1978 by the McGraw Hill 
Company. It seems that it will take at least 8 weeks to get a copy from the 
U.S. However it may still be in print in the U.S. If someone could find out 
for me and I could send a bank cheque across to you and you could send me 
the book. This, I believe would be quicker than getting through a book 
store. Please do not hesitate to e-mail back. I believe that the book is 
around $86 Australian dollars.

    My current research interests relate to the use of numerical
analysis techniques for modeling field/defect interactions associated
with electromagnetic methods of nondestructive testing (NDT).

I have used the three-dimensional finite element formulation
as basis for calculation the induced eddy current density around
the crack in a conductor. The computational results can be used
for optimizing eddy  current probe dimensions. Much information
can be obtained to identify and quantify defects.

Please forgive me for troubling you,but I should be very grateful
if you could help me to receive  some  information,regarding
E-mail newservers addresses where I can get news about trends
in finite elements,electromagnetic computing and applications.

                         Sincerely Yours, Eugene Ismagilov

Elasticity texts refer to such equations as the "compatibility equations."
You should be able to find them, typically, in the first 50 pages

	Ok. Real engineering is a creative process of innovation.  What do
we then call those calculations that you exclude?  We can't call them
engineering too; but we do talk about them alot, so we really should have a
name for them.  And by `we', I mean `we' as a group of professional; i.e.
the answers to these questions should be (nearly) universally accepted.
Next, we should analyze insofar as is possible this creative process of
innovation so as to make sure that it, or at least parts of it, cannot be
`automated' in some way (without requiring artificial sentience).  Then, and
only then, will we have really answered the question.
