Wind Engineering (WE-UQ) / Re: Running WE-UQ EVT

1. We are about to release a new version .. Windows users will have nothing to install as we will include python, dakota and OpenSees .. Mac users will need to install python, bit OPenSees and dakota will be included.

2. by CFD result, do you mean the wind field in the model and pressures on the building as opposed to the building response?

Thanks a lot! It works now!

The problems I had were:
1.Python installation.
2. Dakota and OpenSees installation. At first I didn't have dakota and OpenSees installed. I went through the Installation session on the documentation, did not see that Dakota and OpenSees needed to be installed. Although everything is clearly demonstrated in the video. It may be helpful to tell users clearly to watch the video or to inform the users of necessity of  OpenSees and dakota installation. Often times the documented instruction is enough and people may skip video instruction unless clearly told, especially for convenience in shared office.

I have another question:
After I ran the job which includes a CFD-basic in EVT, I retrieved the data. Here CFD result is of my interest. I am able to get the CFD result from sim.tar.gz from DesignSafe portal, but not from the retrieved data. I wonder if it is what retrieved data supposed to do or something is messed up?


Thanks,
Kate

Thank you for your response.

1) The frame remains linear elastic when subjected to the loads I'm currently using...

2) I should certainly change the recorders to a nicer looking and more compact format. How can I go from 104 to 10? I have 48 recorder files. The rest of the files in the local directories are the main .jason file and other input files.

- I tried running a simulation with the default stick model in WE-UQ at DesignSafe, but that didn't go through either. I got the same problem as with my 2D frame model. The analysis either fails or is finished with no output. I don't know what I'm doing wrong while running at DesignSafe. I was able to run the 2D frame locally with 1000 samples. But I can't handle more samples locally.

you can run w/o that package for what is currently in that code

I'm using Mac Big Sur OS with M1 chip, I had the newest Python version(3.9) as I thought that was for the Mac M1 chip. I don't have problem installing Python, it is the package that I could not install, like hdf5. I have tried a couple of older versions(3.8 and 3.7) and had the same error:Could not find a version that satisfies the requirement hdf5 (from versions: none)

it would be very helpful if it happens you know the solution. Or if you think you can instruct me to install the packages on Zoom with my screen shared.

Thanks,
Kate

the only suggestion i have is to look at the format of the .AT2 file (assuming that is format you wish to use) .. here is an example from one of our examples .. https://github.com/NHERI-SimCenter/EE-UQ/blob/master/Examples/eeuq-0002/src/elCentro.AT2 .. You simply have to replicate that which should be pretty simple to do in python, i.e. write a python script that will open and read the contents of a csv file and then write data to another file.

  • The file will have 3 lines of text describing were record came from:
    simple enough to replicate just write out 3 lines with BLAH on each

  • then a line:

    NPTS= 1559, DT= 0.02 SEC

    again simple, just get case and #points correct (if put points in a list as you read in just length of list)

  • finally what follows that are the points, just loop over list writing  the contents of list to a file.


i suggest you attempt this yourself. If stuck I can post something. But do try as basic programming with python is useful for any engineer.

1) if the model goes nonlinear, one of main reasons it is slow because of the fact you are using initial stiffness iterations.

2) you create 104 output files per run, when you probably could get away with 10 .. 104 is not an awful lot compared to some of scripts I have seen but it is more than needed and it is a good habit to try and open as few files as possible, the record for most  files saved from the recorder commands is around 12k.

it takes about 3 hours to run on my PC I think. It is a 20-story frame (2D) with panel zones and concentrated plasticity elements. So, lots of nodes and elements. I have modified the recorder and processor files as well. Could this be the problem? I separated the node recorders for each story. So the program should create lots of output files. I have attached my model in here.

the system possibly kicked you off system for your choice of nodes and processors .. you are running on stampede's KNL nodes .. each node has 64 core/processors (https://portal.tacc.utexas.edu/user-guides/stampede2) .. so you want more processors than nodes and unless this is a memory/disk intensive job, i.e. large fe model with lots of file writes, you want as few nodes as possible (reduces your wait time) .. how big is the fe model of yours and how long does it take on your local machine to run?
