Years ago I wrote a program in Fortran for a structural analysis class. At the time I had very little programming experience and mottled my way through the assignment. Fast forward to now and I'm attempting to teach myself Python 3. I figured I'd would try to convert the old program from Fortran to Python. I've made some good progress but I've hit a wall. I've got the program running to the point where all the element stiffness matrices are defined and combined into the structure stiffness matrix using the code number technique. The structure stiffness matrix is triangular. At this point in the Fortran code, it calls a subroutine which I believe solves for d in [K]d = p using Gauss Elimination. Here's the Fortran code:

      DIMENSION BGK(100,30),XL(60),COSX(60),COSY(60),COSZ(60),SK(6,6),
     1AR(60),NC(60,6),QL(100),P(60)

I make it the continue statement after line 84 and my head fogs up. I would appreciate it immensely if someone could help me understand the rest of the code so I can convert it to python. I've attached my python code and am open to any suggestions on how I could make it better. This is my first attempt at writing in python.

Thanks

may i ask?, can the fortran code read every example of truss??.
i really want to know, cause i have home work to do. thank you very much

I could not run it...
Please tell me whats happening

First of all, veblinriche, I apologize. I did not see that you had commented. It calculates the axial force in each member and the displacement of each joint. It is only valid for plane trusses with no zero force members, meaning it cannot do buckled analysis.

MrEfgo, the program prompts for geometric information for a plane truss and then calculates the axial force in each member and the displacement of each joint.

Hi

Nice to see fortran to python conversion. I am a beginner in python. BUt have fortran coding experience.
If i provide a small fortran program , would it be possible to provide an equal python code. If yes I will provide the fortran code.
Appreciate your help in this regard.

That depends on how complex the code is and where you are having problems. I suggest you start a new thread and see what happens. We tend to offer help rather than solutions.
