State parameter for user element

[avytin]

Hi,
I do have very small experience in c++. What I am interested in doing is implementing a user element but I want the formulation to include a state parameter, that at first gets initialized, changes at every iteration and is committed when convergence is achieved. Which approach would you recommend using?

look at a simple nonlinear material, e.g. ElasticPP to see how state variables are handled. then look at the Truss element to see what ethods need to be implemented for
