Thanks PSE I will look through it.

I am looking for a comprehensive list of costs of different metals such as steels, Al etc for variety of shapes and sizes. One way is to call the vendors but I need comprehensive and LOT of information. I realise that the rates keep changing but I just need ball-park figues. I tried googling but...

Anybody familiar with this cost estimation software: COSTIMATOR. I did a search on eng-tips but did not find any references. Please let me know if anyone has used it. Thanks Ahad

Thanks all for your input. So a Master's degree may be a plus but Ph.D. is more of a PR value. I do agree that experience would be a more preferrable asset than degrees. But do these opinions only stand for the Project Management Specialization or the field of Eng Management in general. What if...

I have a masters degree in mechanical engineering and 4 yrs experience working with force transducers. I am thinking of getting my Ph.D. (Part-Time) in Engineering Management with specialization in Project Management. I wanted to know if it is too early to get a degree in Project Management...

Is there a simple command in Fortran for solving system of linear equations. Like matlab has x = A\B to solve Ax=B. Thanks Ahad

Thanks rob768 & johnhors. johnhors, is case 1 usable if the surface is sandwiched between two plates using bolts. Thanks Ahad

What is the best way to simulate a bolted constraint. Say it is loaded with 3 forces and 3 moments along each axis. The two ways I can think of are 1. If there are 6 bolts on a bolt-circle of dia 6". Then I would constrain a "ring" with outer dia 6.5" and inner dia 5.5" (Depending on the...

lukeme, Try typing in "introduction to FEA" or "stiffness matrix" etc in google you should come up with hundreds of websites of course notes. Ahad

Thanks George, The answer to your question "...but do you need an array to hold the results of the location of the "1"? is Yes. That is exactly what I need. ahad

Thanks HTH, I am going through the information. The reason i need this functionality is that I have a matrix D=(1,1,1,0,0,0,1,1,0,0,1,0) which I have stated in my program as REAL, DIMENSION(1,12):: D D = RESHAPE((/1,1,1,0,0,0,1,1,0,0,1,0/),(/1,12/)) I want a matrix F such that it tells me the...

Hi, I am new to Fortran and using Compaq visual fortran. I tried looking up on google but couldn't resolve ths problem. I need to declare a matrix but the dimensions of this will not be knwon till the program gets to the executable part of the code. From the executable part i get a value for...

Thank you all. This is what I understood from your comments: Since Matlab does not interact with the hardware like other low-level languages it takes longer to run the code. And when the dofs involved is large that makes it even more painful. Hope I got it right. Thanks ahad

This is just a curiosity question. Are there any commerical FEA software that have their code written in mathematical software like Matlab, Mathmatica or Maple? I am guessing the answer is "NO". Can anyone tell me why? Thanks

Try adding a small radius at the foot and see if the solution converges.
