I created a concentrated plasticity 3D model using element zerolength.
My set up for analysis is:
constraints Plain;
numberer RCM;
system BandGeneral;
test NormDispIncr 10e-6 1000;
algorithm NewtonLineSearch;
integrator LoadControl 0.001;
analysis Static;
analyze 5000;
At the end of analysis I obtained this error:
WARNING BandGenLinLapackSolver::solve() -LAPACK routine returned 25
WARNING NewtonRaphson::solveCurrentStep() -the LinearSysOfEqn failed in solve()
StaticAnalysis::analyze() – the Algorithm failed at iteration: 0 with domain at load factor 0.001
What can be the error in the model?
Thanks
