Fortran

[Harryboy]

Hi, I dont know if this is the forum for my question but here goes. I'm writing a FEM program in Fortran and I have som problems when reading the input file into the program. My goal is to be able to more ore less read ABAQUS input files into my code, so do anyone have any idea where to start looking or any webbpage to look up??

Best Regards

Sounds like you are working on a seriously challenging project - best of luck.

Fortunately, it should not be that difficult to support the ABAQUS input file format. I recommend that you implement one command at a time...

Can you explain your question again? I don't quite understand what you are looking for.

Well, I believe its my poor knowledges in how Fortran handles in- and out-put thats
the problem. At the moment, I use READ(nin,*) to read the node, element sets,
etc but I do not use any fancy approach to identify for instance the *ELEMENT,...
card, making the input file rather restricted.

The finite element code it self is not very fancy at the moment, I just started
out with simple J2-plasticity and some elastic Neo-Hooke models using large
strains, but I find it amusing to work with so time will tell what will turn out
from the project.

One further question: Do anyone know a free post-processor that may be downloaded?
