Sang-ri,

I really appreciate it. I will start using this new update soon and let you know in case there is any problem, which I doubt.

Regional Hazard Simulation (R2D, rWhale) / Re: Error in running examples
« Last post by jyzhao on October 27, 2023, 04:45:20 PM »
Hi,

Collecting inventory data is difficult. Although R2D can be used to assess the performance of building inventory stocks in natural hazards, it is not designed to collect building inventory data. You may refer to the testbeds in R2D https://nheri-simcenter.github.io/R2D-Documentation/common/testbeds/sf_bay_area/index.html to see examples of collecting building inventory data. If you would like to study highway transportation infrastructure, the BRIALS-transportation tool (which can be found in the "Tools" drop-down menu) in  R2D can generate the transportation infrastructure data for HAZUS-style earthquake performance assessment. Please let us know if you need further assistance.

Best,

Jinyan

Regional Hazard Simulation (R2D, rWhale) / Re: R2D on Linux HPC

Amir,

It is possible to run on such a system if you can build both the backend and frontend. I am in the process of builidng a Dockerfile which you could use to see which packages are needed on your system and what the build process is. The Dockerfile uses Ubuntu18.04 as its base. The biggest issue I foresee is getting Qt version 5.15 installed. Failing to install the frontend would mean you could not use the GUI. The backend has a simpler build process and you could run the computational simulations there and possibly view results in python.


timeline for Dockerfile is probably next week (today being the 10/27/2023 for those others looking at this message). The Dockerfile will be in the R2DTool repo on github.

The purpose of the docker images is to run the frontend and backend on one of the TACC Frontera HPC compute nodes.

Hello,

I am interested in running R2D on a Linux machine, and I am wondering if it is possible.
I would appreciate it if you could provide assistance in this regard.

Uncertainty Quantification (quoFEM) / Re: Parallel execution on a Windows HPC

Hi,

I apologize for the delayed update. We have finally updated the quoFEM (v3.4.0).

To run the analysis with all 128 cores, please locate the attached config.json file in the same directory as the quoFEM executable. Then, you can start the quoFEM application as usual.

Detecting the configuration file, it will automatically overwrite the evaluation_concurrency in dakota.in to 128 (64*2). Currently, the multiplier can only be an integer.

Please let us know if you have any trouble or questions.

Thank you,
Sang-ri

Uncertainty Quantification (quoFEM) / Re: Using quoFEM for GP based Surrogate Modelling and Sensitivity Analysis,
« Last post by Sang-ri on October 25, 2023, 08:45:04 PM »
Hi,

Thanks for the post! I have some quick questions before going into details.

1. Can you let me know the dimensions of the model input (=number of the parameters whose contribution to the responses will be inspected) and output (=number of the responses from a simulation run) of interest? I am assuming that the output dimension is 50, but I just wanted to clarify. I believe the number of simulations you ran is 512.

2. Regarding the sensitivity analysis that did not converge, was it performed using quoFEM?

Thanks,
Sang-ri

Uncertainty Quantification (quoFEM) / Using quoFEM for GP based Surrogate Modelling and Sensitivity Analysis,
« Last post by atish on October 25, 2023, 04:55:13 AM »
Dear SimCenter Team,

I am a PhD student at the University of New South Wales, Australia. Currently, I am working on a global sensitivity analysis using a high-fidelity atmospheric model. I have considered 50 reaction rates (input parameter) as my input quantity of interest, whose effects I will be quantifying. Using 512 sets of perturbed reaction rates, I tried to run my model and perform sobol analysis. However, my sobol indices are not converging, as I think my sample size is small. Now I have decided to create a surrogate model using the Gaussian Process (GP) Regression method and then perform sobol analysis. I am new to machine learning.

My question:
1. Since my input parameter is 50 and I have 512 output data, can I use quoFEM to perform sensitivity analysis.
2. If not, then can I use quoFEM to create GP based surrogate model.

Hello, would you please guide me on how I can get data on a county (San Diego) to create a new scenario? (Hurricanes and earthquakes) (like Buildings, number of stories, elevation, type of the material of buildings, and so on)

Hello,

This may be because the Zenodo API server is not working. You could try to download the example files from our GitHub repo: https://github.com/NHERI-SimCenter/R2DExamples. After you download the example files. You can load the example to R2D by going to the "File->Open" option in the menu bar, and load the "/R2DExamples/E1BasicHAZUS/input.json" file.
