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: Dis...

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 Runni...

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 rega...

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
