why system SparseGEN doese not work in OpenSees 2.4.3 ?

[mehdikia2519]

dear fmk

A model which is used " system SparseGEN " command was developed . the model is run with latest version of opensees ( i.e. OpenSees 2.4.3 ) and the following errors return :

DistributedSuperLU::DistributedSuperLU(int npR, int npC)
commands.cpp: DistributedSuperLU
commands.cpp: DistributedSparseGenColLinSOE
WARNING: CTestEnergyIncr::test() - failed to converge
after: 100 iterations
NewtnRaphson::solveCurrentStep() -the ConvergenceTest object failed in test()
StaticAnalysis::analyze() - the Algorithm failed at iteration: 0 with domain at
load factor 163724
OpenSees > analyze failed, returned: -3 error flag

it is noted no problems are reported when other system commands such as " system ProfileSPD , system BandGeneral " are used .

thanks for your helps

[fmk]

are you running a a parallel application?

[mehdikia2519]

hello fmk
your guess is true , i run openSeesSP . your mean is SparseGEN does not work in parallel application ?

[fmk]

use Mumps instead if parallel (it is much faster)
