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...

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.

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.

The only way I could get things to work was using cygwin ... Any idea what the error is ... $ mpirun -np 10 OpenSeesMP.exe run.tcl -------------------------------------------------------------------------- There are not enough slots available in the system to satisfy the 10 slots that were requested...

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

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": ...

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":...

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...

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...

That is correct!

Thanks for the link.

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...

I checked the manual below, it seems to be optional.

Can please explain a bit more?

Much appreciate it.

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...

Hi I a getting many warnings messages like below. I am just curious what is that suggesting exactly? Please let me know your valuable comments if any.
