I tried the two following ways: 1) Calling the OpenSeesSP executable from MATLAB: clear all clc fname = tempname; while exist(fname, 'file') fname = tempname; end fid = fopen(fname, 'wt'); fprintf(fid, 'mpiexec -np 4 OpenSeesSP Test.tcl'); system(['OpenSeesSP < ' fname]); Then MATLAB responded: inva...

Thanks for the comment,

Actually, the executable can be run without any problem. The problem is the "mpiexec" command! Matlab reports it as invalid command ...


Best regards,

Hi, I have problem in coupling matlab with OpenSeesSP. When I run my code with direct use of OpenSeesSP executable, everything goes well. However, when I try to run it through matlab platform, it doesn't recognize "mpiexec". Generally speaking, I have problem in commanding "mpiexec -n...

Hi Frank,

Could you please provide me a relatively complete example on OpenSeesMP?


Best regards,

Thanks frank,

Just so you be aware of that, the uniaxial material object, ReinforcingSteel, is also not compatible with OpenseesSP.

Will try that on OpenSeesMP

Hi all, Three questions: 1) I am trying to run a comparatively large FEM of a framed RC structure in parallel using OpenSeesSP. I noticed that job aborts if I use Layered Shell. However, if I use elastic Shell MITC4, the code runs perfect, and no problem occurs. It seems that the layered shell eleme...

Hi Frank, Yes! I have tried on sequential OpenSees using UmfPack. It works fine, and no problem occurs even if I run it in a loop for 1000 of times. However, sequential approach takes a lot of time. Could it be a systematic problem of our machine?! Others are working on linux, and I am working on Wi...

Hi Frank,

All in all, I have 553 nonlinear elements with 2352 cross-sections (integration points), and 100 fibers at each cross-section plus 1728 ShellMITC4.

This is only a 3-story RC building, and I am going to work on larger models!

Thanks for your help,

Hi,

What is the following error, and how can I fix it?

Warning Mumps Parallel Solver :: Solve(void) -Error 13 returned in substitution dmumps

and after a couple of warnings, job aborts:

Thanks for your help

Hi Frank, Yes, I am running all in a single script! My main script looks like the following: For i = 1:1:1000 Building nodes and boundary conditions in the main script source Material.tcl source Section.tcl Building Model (Elements, Loads, Mass) in the main Script Recorders in the main script Nonlin...

Hi Frank, Thanks for your reply, The fact is that the code with its all elements, sections, load patterns, and almost everything related to the analysis part is working perfect for a 2D frame. But then when I apply it to a 3D model, such a problems occurs. I am running two analysis in series. First ...

Hi, I am running a relatively big model in OpenSees-SP. Sometimes I get the following error. I would like to know the reason, and How can I fix it? Error: Incorrect number on entries for vector received: 2 expected: 8550 Also, a window pups up which says that your computer is low on memory. I am run...

Thank you Dr. McKenna.
Thanks also to you, xiell, for your generous help. I will definitely use my chance.

Hi, I understood that layered shell module is also added to the new released version. However, I cannot find the command of layered shell in the Section and/or Element Modelling_Commands. I generally follow the Command Manual in the OpenSees Wiki. Does it get updated time by time? From where I can f...

Hi,

I was working with OpenSees 32 bit on Windows till the new version, OpenSees 2.4.2 released. I checked it but I couldn't find any difference in CPU and Memory Usage. Thus, what is the advantage of 64 bit version?

Am I doing something wrong?

Thanks for your comments!
