Dear Dr.silvia Mazzoni

I have modeled a 3 story frame.After running this error occurs :

WARNING BandGenLinLapackSolver::solve() -LAPACK routine returned 12
WARNING NewtonRaphson::solveCurrentStep() -the LinearSysOfEqn failed in solve()
StaticAnalysis::analyze() - the Algorithm failed at iteration: 0 with domain at
load factor 0.1
OpenSees > analyze failed, returned: -3 error flag

BandArpackSolver::Error in dgbtrf_
Warning FrequencyAlgo::solveCurrentStep() - the EigenSOE failed in solve().
EigenAnalysis::analyze() - algorithm failed
missing function argument at _@_
in expression "pow(_@_,0.5)"

What could they be?

are you trying to do an eigenvalue analysis?
the system is unstable....
