what does domainChange command do to parallel a model and when that is required?
I am trying to make use of OpenSeesMP to speed up my analysis. I have been studying the below link https://opensees.berkeley.edu/OpenSees/workshops/parallel/OpenSeesMP.pdf On page 9 and 10, it describes how to analyze a large model to run in parallel, however, I can't make sense of domainChange comm...

Re: How to install/setup OpenSeesMP.exe / parallel on windows?
I downloaded an older version of MPICH from https://www.mpich.org/static/downloads/1.4/ and that created mpi dlls and placed them in c:\Windows\System32.
If I had time I would have compiled a recent version.

Re: How to install/setup OpenSeesMP.exe / parallel on windows?
Ok, the below error had to do with the -np flag which sets the number of processors. When I set -np to actual number of processors the above error doesn't occur. However, I still get missing mpich2mpi.dll errors. Very weird because I have installed "Microsoft MPI v10.0" already.

How to install/setup OpenSeesMP.exe / parallel on windows?
Hi All,
I am trying to run the OpenSeesMP. To achieve that I have installed Microsoft MPI, however, it keeps complaining about the following two dlls.
Please let me know if you know any workaround.
Regards,
mpich2mpi.dll
fmpich2.dll

Is it possible to have two elements with the same element tag?
I exported my model using print -JSON -file somefile.json. However, I get to many elements with same tag number. I am wondering if that is print issue or element with same tags are allowed ? Please let me know Regards {"name": 1.20011e+06, "type": "ZeroLength", "nodes": [1001, 100102], "materials": ...

Why element node in "print -JSON" is different from "print -ele"
I am trying to get the list of all elements and nodes so I use ... print -JSON -file model.json but then the output would be different from a typical print -ele command. print -ele 9001 From JSON it would look like below {"name": 9001, "type": "TwoNodeLink", "nodes": [1201, 1.0012e+06], "materials":...

how to save nodes' new coordinate after an analysis?
I have helping a civil engineer to automate part of his work ... I need to have the new state of the model after running a pushover analysis. The starting state I can retrieve using "print -JSON -file model.json" command. However, if I try the same after analysis I seem to get the initial state of t...

Re: Does OpenSees solve least square problem?
Hi Scott, I was able to find the issue and you were exactly right. I had couple of elements with very stiff elastic martials as listed below: uniaxialMaterial Elastic 40 1.0e15 uniaxialMaterial Elastic 3001 [expr 1.0e15] I know that there are different types of problem formation depending on type of...

how many element tags do I need to define a Two Node Link Element?
I am new to OpenSees and I am trying to define a Two Node Link Element. My physics knowledge dates back to Halliday physics course back in university. I am just curious how many material tags do I need in order to define a Two Node Link Element and what they are representing. Much appreciate your co...

Re: WARNING TwoNodeLink::setUp() - element: XXX
I checked the manual below, it seems to be optional.

Can please explain a bit more?

Does OpenSees solve least square problem?
Dear Experts, I am helping a civil engineer solving a structure gravity and pushover analysis load. However, I noticed that when the number of diagonal elastic elements (going to be replaced by viscus dampers later in dynamic seismic analysis) is increased, there is lower chance of convergence. I ha...
