-iter in nonlinearBeamColumn element ,

[gaohouzhi]

element nonlinearBeamColumn $eleTag $iNode $jNode $numIntgrPts $secTag $transfTag <-mass $massDens> <-iter $maxIters $tol> <-integration $intType>

in this command , "<-iter $maxIters $tol>" means $maxIters maximum number of iterations to undertake to satisfy element compatibility (optional, default=1) in the mannual.

My question is where can I find the theory to explain the iterations to satisfy element compatibility?

In some common papers or books , I cannt find the discriptions about iterations on element.

could you give me some direcitons about which paper I should read to make the meanings in this tcl command more clear?

Beg your help eagerly.

maxIter is not in the papers or books .. the papers do show that the element uses a force forumulation and does internal newton like iterations to find the forces at the ends given the displacements at every step.
