bandgenlinklapacksolver warning error

[mijin]

Hello. i'am opensees first users.. i got this error when gravity analysis..
↓
WARNING BandGenLinLapackSolver::solve() -LAPACK routine returned 2
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

I guess that its problem is modling. but i don't know where is error and why because my model looks like different other conventional model..
finally i wanna pushover analysis structure shaped angle..
shape of my model looks like example below
Example)

■ fix (node 2)

■ ─ ─ ─ ─ ─ ─ ● roller(node 3)

please help me
my script file is below..

look at the element connectivity a.k.a the nodes at ends of the 2 elements of yours

[mijin]

i don't know the problem of connecting node..
what is problem nodes at ends of the 2 elements of mine?

[fmk]

look at element 2 nodes 1 and 3 .. node 3 is only node fixed and it is a pin! .. so either you goofed on your boundary conditions or ele 2 was supposed to go between nodes 2 and 3.
