why not update the option GA

I try to get M- phi of one beam .(P -delta is ok,also.) however the section is not :!:Continuous section.just like Box Beam with Corrugated Steel Webs .I try times ,still getting ： ~~~~~~~~~~~~~~~~~~~~~~ WARNING BandGenLinLapackSolver::solve() -LAPACK routine returned 20 WARNING NewtonRaphson::solve...

dear niloufar:
Have the elastic deformation problem been solved? can /should it be calculated by hand?

the same question，help~~！

good question，better answer！

"rigidLink"？or''equalDOF''?

thank you!

Dear caosasa ,i still cannot understand why the ratation of node 2 are different?
