Understanding the FEA Code for simple beam analysis

[Faisal]

Hi to all!

I am a graduate student of Structural Engineering and have passion for coding in Finite Element Analysis.

My query is:

1. I want to learn how the CODE for line element works.

2. Provided that it is loaded with a Point load

3. And Displacements, Shear and Moment is required in output.

I have already downloaded the source and build a solution file in VS2005 after a lot of difficulties and errors.

Waiting for a reply for making the above code from scratch.

if you want to understand the existing code for the OpenSees line elements i suggest you start with the elastic beam column and linear coordinate transformation.

OpenSees/SRC/element/ElasticBeamColumn2d.cpp

OpenSees/SRC/coord/LinearCrdTransf2d.cpp

if you want to write new code i suggest you look at the code in OpenSees/PACKAGES/NewElement .. you can write cpp/c or fortran elements.

ok I am studying these files and will discuss if something is hard to understand by my self.
