Can anyone help to solve the following problem?
I use the fiber section (annular section) for nonlinearBeamColumn element.
And I define analysis option for dead load as below:
constraints Plain
numberer Plain
system UmfPack -lvalueFact 40
test NormDispIncr +1.000000E-12 25 0 2
algorithm Newton
integrator LoadControl +1.000000E+00 4 +1.000000E-03 +1.000000E+00
analysis Static;
But when I run, the below error occurs
WARNING: CTestNormDispIncr::test() - failed to converge
after: 25 iterations current Norm: 31.4213 (max: 1e-012, Norm deltaR: 5.79451e+012)
NewtnRaphson::solveCurrentStep() -the ConvergenceTest object failed in test()
StaticAnalysis::analyze() - the Algorithm failed at iteration: 0 with domain at load factor 1
Note: In case of Transient Analysis with annular section, the result is ok.
And In case of Dead Analysis with general section and forcebeamcolumn element, the result is ok also.
Thanks advance!

Thanks for your response, EricsonEncinaZ
In my cases, I need a solution for Dead analysis.
The Dynamic analysis worked already.
