I am trying to recreate this Basic Truss Example using Navigator. I got this error when running (using Navigator or directly in OpenSees):
WARNING BandSPDLinLapackSolver::solve() – the LAPACK routines returned 1
WARNING Linear::solveCurrentStep() -the LinearSOE failed in solve()
StaticAnalysis::analyze() – the Algorithm failed at iteration: 0 with domain at load factor 1
OpenSees > analyze failed, returned: -3 error flag
I input exactly same input with the Example including the analysis options. I even checked the tcl files generated/written by Navigator and couldn’t find significant difference with original code in the Example. If I use elasticBeamColumn element with same properties, it run well and has same result with Example, but it doesn’t work when I use Truss element.
Here is the mat and tcl files. Any suggestion? Really appreciate your help.
