hello fmk
SuperLU is used . your mean the only option for me is Mumps solver ?

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

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: DistributedSp...

dear fmk when a model is run in a parallel system with one processor ( i.e. " mpiexec -np 1 OpenSeesSP pushover.tcl " ) , there is no problem but when more than one processor is used ( i.e. " mpiexec -np 2 OpenSeesSP pushover.tcl ") the following errors return Slave Process Running 1 StaticDomainDec...

hello everybody According to the documentation on the web for using Opensees parallel executable (i.e. OpenSeesSP) it is necessary to install MPICH2 to have mpirun .it is done but i have mpiexec on my computer instead of mpirun so it is not possible for me to run openseessp . is there somebody to te...

Dear fmk I read the Documentation described openseesSp and OpenSeesMp use, additional commands, modified commands, and some examples (http://opensees.berkeley.edu/OpenSees/parallel/parallel.php ) completely . according to this document (section 4.2) it is possible to use the script that is exactly t...

dear brag006
thanks for your help but i don't understand your mean . can you explain more in detail ?

dear fmk when OpenSeesSP interpreter is run from the command line with the command " mpirun -np 7 OpenSeesSingleParallelInterpreter ida.txt " , It returns the invalid command name " mpirun " (look at the openseesSp screen copied in the following ) . what is the reason ? best regard """""""""""""""""...

Hello every body
I want to know How it is possible to parallel all cores of one CPU by opensees software to reduce runtime ? if somebody do this , let me know about the procedure
Thanks a lot in advance for your helps

dear hnaderi and barg006
thanks for your attehtion
both suggested teqniques were applied befor , but nothing achived . it is noting , convergence problems remove when other type of model is used .

dear frank Convergence problem is happened during incremental dynamic analysis when the Modified Ibarra-Medina-Krawinkler Deterioration Model (Bilin Material) is used . it is worthy to note this problem cannot be solved by utilizing the smaller time steps . It would be your kind if you help me with ...

dear frank
some part of your answer about drift was missed . please type it again .
thanks a lot

Dear Frank please let me know more in detail about two commands one is drift recorder and the other is nodal acceleration recorder when we use drift recorder , this command calculate difference between displacement at two level i.e.( Displacement at level i+1 - displacement at level i ) or calculate...

Dear fmk I hope this email finds you well. you know incremental dynamic analysis (IDA) is a powerful computer -intensive method that offers a comprehensive evaluation of the seismic performance of the structures ,however it is a more time consuming procedure . it seems one of the best solution in or...

Dear fmk
thanks for your advise
