Frank,
I am changed the fibersection3d code to give a nonlinear strain profile. However, I have noticed that when I use it the time to solution goes up significantly. I think the increase in time is due to how the next trial state is selected. I don't know how to go about changing things to reduce the solution time. Since you know the code base, could you give me some advice on how to work it? Thanks

yes .. presume the problem wou are having is when using the force beam column element .. you
just may need more than the defealut number of iterations to converge .. you could try increasing the default max number of iterations at the element level that occur before
initial iterations and step subdivisions take place
at global level what you need is a better prediction of where you are going .. you could try KrylovNewton or NewtonWithLineSearch .. they might help.
