Note that, when fiber numbers are used in the recorder,in the xml output, the fiber locations are the same for the fiber numbers from 0.0 to 0.9, which are for the 1st fiber. Beginning from fiber number 1.0, it switches it to the 2nd fiber. So, for the fiber numbers in the recorder command, we can u...

Hi all, I want to clarify some issues related with fatigue material damage recorder. For fiber section elements, the argument that follows after "material" is actually the fiber number. It has nothing to do with the material tag. Indeed, you can use "fiber" instead of "mater...

Vesna, To follow up an old discussion, in the following recorder command (taken from the old post above), is the tag after the material (1) really related to the material tag of the parent material? recorder Element -file Damage_ele1.txt -time -ele 1 section 1 material 1 damage I feel like that is n...

Hello, I submitted a parallel job using OpenSees NEES resources (8 processors). The analyses started and worked well for about 15 minutes, then my job stopped. In *.stderr file, I found this: mpirun noticed that process rank 1 with PID 663 on node NEEShub exited on signal 24 (CPU time limit exceeded...

Hello,
Is there a chance to post the "Modeling Diaphragms in 2D" session to Youtube or somewehere?

Thanks,

Hello,

I can't download the latest parallel version. I guess there is an issue with the link.
Thanks,

I am getting the following message in the output (real time) file with revision 4543 (version 2.3.0.alpha) . UmfpackGenLinSOE::setSize() : nnz: 2737 lvalue: 27370 I wasn't getting this message in the previous version (2.2.2f). What does this mean? and does it have an effect on the results? I am stil...

Thank you Frank. We could build both SP and MP.
Also, we can now use more than 1 node as we switched from OpenMPI-1.3.3 to OpenMPI-1.4.3_gnu.
So problems solved!!
Thanks,

We are getting this error while trying to build OpenSeesSP using revision 4541.

TclModelBuilderUniaxialMaterialCommand.cpp:(.text+0xdc61): undefined reference to `TclModelBuilder_addPyTzQzMaterial(void*, Tcl_Interp*, int, char const**, Domain*)'

I will post the makefile in the next message.
Thanks

Hi Frank, It looks like the problem was due to OpenMPI version 1.3.3. VT supercomputer staff says that they resolved the problem using OpenMPI versions 1.4.3 (GNU) and 1.4.2(intel). So we tried to build OpenSees again (with latest source code,revision 4541) using newer version of OpenMPI but got an ...

Frank, I talked to our supercomputer staff, and they told me that MPI has been tested many times and is currently in use by many people. We are running OpenSUSE 11.1 and OpenSees was compiled with OpenMPI-1.3.3. As an example, the following hello world script prints more than one hostname. #include ...

Hello, I am running parametric analyses using OpenSeesMP on a cluster. In our cluster each node has 8 processors. In the qsub file, I ask for 5 nodes and 8 processors so a total of 40 (#PBS -lnodes=5:ppn=8). I just realized that OpenSees is only using one node though. OpenSees reads the total CPU ri...
