How to Acquire Demo Version of Fortran
(OP)
Hello all!!! How can we acquire a demo version or evaluation version of Fortran? Is it available in the internet? I want to study how to program the stiffness matrix method for evaluating forces and moments on the structure....Thanks in advance...Cheers!!

Anyway, as well as the several open source versions of Fortran I can recommend Silverfrost Fortran, which has a free version for non-commercial use.
But if you are wanting it for self education about structural analysis, why not use a spreadsheet?

The evaluation ones are Intel (you will need at least a P4 or a dual core otherwise it won't even install), Lahey.

Nhelzki - Fortran doesn't have built in libraries for the stuff you want. You need to go to a site like http://www.physics.unlv.edu/~pang/cp_f77.html. If you're doing lots of simultaneous equations, use Choleski (or LU decomposition). It is a lot faster than any of the Gaussian techniques, especially for big matrices.
You could always use the Matlab type tools like freemat if want to get the algorithm right first. Unlike Fortran, FreeMat has most of the stuff you require built in. Only problem is it is quite slow. It leaves you time to concentrate on the problem rather than the programming. Once you've fixed the problem, and you want a faster solution, translate to Fortran for speed.
