A Command Line Two Dimensional Matrix Analyzer
A Command Line Two Dimensional Matrix Analyzer
(OP)
Does anyone know if such a thing exists? I'm looking for a free command line (simple executable file) that I can pass my information to on the command line and it will spit out the reactions, shear, moments, deflections etc... into a text file that I can parse with another program if need be. My intent is imbed this program or call it from other programs and excel spreadsheets. Basically I'm looking for the equivalent of STAAD (the program I am most familiar with for structural analysis) but can be run from the command line by passing it a input text file with all my parameters. I only need the ability to analyze beam and truss members (linear, one dimensional elements) and not plates or bricks. If such a thing does not exist I will have to create it.

something like
feasolver -options thisrun.cf
Nastran dumps out text files of inordinate length which can be picked up by any program. parsing them is tiresome but fully documented

Not quite any solver, a solver embedded in a spreadsheet can't be run from the command line.
But my question is, if you generate the input in a spreadsheet, and read the results back into a spreadsheet for post-processing, why would you want to run the solver from the command line?
My blog post here:
http://newtonexcelbach.wordpress.com/2012/09/21/da...
has links to Excel based 2D and 3D frame solvers, including open source code.
"Real soon now" there will be a Python based version, which it should be possible to adapt to run from the command line, if you want to.

OK, you won't be able to do that with my spreadsheet, although it comes with some compiled solvers that might be of some use.
Another option if you are happy to do some coding and compiling is to look at "Programming the Finite Element Method" by Smith and Griffiths, which comes with complete Fortran code for frame and full 3D FEA solvers.

if you want free FEA program, then use Calculix.
