Hi Everyone, I have a relatively large model that is taking approximately 12 days to run on a cluster. Unfortunately I'm not actually utlising the full capabilities of the cluster because I don't know how to run this large model using multiple processors. Basically I successfully use OpenSeesMP for ...

Thanks for that, your work is much appreciated.

Do you have any advice on temporary solutions? Time is of the essence and this is a really big obstacle for me.

Any suggestions would be much appreciated.

Regards,

Any suggestions on solving this problem? It seems to be a weird and I can't find the source of the problem

Hi, I am running an analysis using OpenSeesMP on a cluster and using the Mumps solver. I am getting the following error: WARNING MumpsParallelSolver::solve(void)- Error -9 returned in substitution dmumps() Work array too small; use -ICNTL14 option, the default is -ICNTL 20 make 20 larger The interes...

Also is it possible to fix the element so it does work in a transient analysis? If so, any guidance with that would be much appreciated.

Thank for the prompt reply professor. Do you have any recommendations for the kind of interface elements I could use in my model of a wharf. I am developing a 2D model including the soil domain (SSPQuad) and the wharf (dispBeamColumn). How can I capture the response at the interace?

Does anyone have any experience with using the BeamContact2D element in a transient analysis? I have been having significant issues trying to get it to work at the interface between piles and surrounding soil. I have been having convergence issues even though I have tried a wide variety of changes t...

I only have the problem with a 778 triangular elements out of 9443 total elements. I thought it might be possible to create the triangular nodes and elements in a ndm 2 ndf 2 system and then constraint them using equalDOF in the 1 and 2 direction to duplicate nodes in the ndm 3 ndf 6 system which wi...

I tried that but I am getting singularity issues. Here's the error when I assign Mumps for sys_of_eqns WARNING MumpsParallelSolver::solve(void)- Error -10 returned in substitution dmumps() cause: Matrix is Singular Numerically and when using BandGeneral: WARNING BandGenLinLapackSolver::solve() -LAPA...

Hi, I have a gate that has already been meshed using another structural analysis software and contains quadrilateral and triangular plate elements. In converting the input files from this software to OpenSees I have found that there appears to be no triangular shell elements. Are there any elements ...

Hi,

Just checking what the purpose of this output in NodeRecorder.cpp on line 804

opserr << "NodeRecorder::initialize - numNodes: " << numNodes << endln;

It's coming up in one of my analyses and not sure if it is an 'error' or not

I am not sure if this is an error or not, but I am getting this message when I run a large model on OpenSeesSP on a cluster using several processors:

You just increased the maxndoms: 5 4


Does this have any meaning? It comes when I run 8 processes for example but not when I run 10.

I am facing convergence problems and I developed some code to try out different soultion algorithms and in most cases that works fine. However for a small number of simulations I am still not converging even after decreasing the timestep. In some cases changing the convergence test resulted in conve...

I only get memory corruption problems when I use mumps. I changed to umfpack and no longer memory problems. Any thoughts on why could that be? I tried using the -intcl14 option but no luck.

I am running a medium size model through approximately 100 eq motions and using OpenSeesMP to run multiple processes. I used code similar to the example provided with the source code. After many days of having random errors related to memory (glibc errors) it appears I have a race condition. I read ...
