system and algorithm failed

[wdylut]

Dear my friends,
I have been learning this software for about two months,when i am programming my command flow ,I met the warnings showed below,I have been thinking about it for several days but failed to solve it,I hope you can help me.
####
WARNING BandGenLinLapackSolver::solve() -LAPACK routine returned 6
WARNING ModifiedNewton::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
#########
if necessary ,I can give you my Tcl document,thank you!!!

the algorithm is failing beacuse the solver is failing .. the solver is failing due to an incorrect initial model if at the start, or the model is going noninear and your properties are such that the system goes unstable.

Thank U,I have found the problem that i used the pinching4 mat in a wrong way.
