Regional Hazard Simulation (R2D, rWhale) / Re: Unable to login in Designsafe
« on: August 15, 2024, 07:08:45 PM »
Hello Bofan,

Thanks for posting. To help us track the error, can you provide us with the "Remote Application Directory" and "Tapis App" values in the R2D preferences? For example, my Tapis App ID is "simcenter-rWhale-stampede3-1.0.0u1".

Thanks,

Jinyan

Hi Bofan,

This issue should have been solved in the latest release, in which "simcenter-rWHale-frontera-4.4.0u1" is the default Tapis App ID as defined in R2D preferences.

Please try to use the latest version posted on DesignSafe.

Best,

Jinyan

Hi Bofan,

I am sorry that the documentation section you pointed out is outdated, and the running on DesignSafe function has been moved to the R2D graphical user interface.

To run on DesignSafe, you can set up the running workflow in a similar way as running locally. After, you can submit the job to DesignSafe by clicking the "RUN at DesignSafe" button next to the "RUN" button on the R2D user interface. Some instructions are provided at the bottom of https://nheri-simcenter.github.io/R2D-Documentation/common/user_manual/usage/desktop/usage.html.

Hope this helps.

To run on DesignSafe, please change the Tapis App ID to "simcenter-rWHale-frontera-4.4.0u1".

Please let us know if there are any other issues.

Best,

Hello,

Thanks for using SimCenter forum.

For the first question, it is likely because a new Python is installed and set as the default Python on your computer. The new Python may not be compatible with SimCenter Apps. Could you please reply with the operation system you are using and the Python path defined in your R2D "preferences" menu bar? If you are using a MacOS, you can see info at "https://nheri-simcenter.github.io/R2D-Documentation/common/user_manual/installation/desktop/install_macOS.html#install-python-3-9" about how to get the correct Python to use.

For the second question, we are investigating and will let you know the results as soon as possible.

Best,

Jinyan

Regional Hazard Simulation (R2D, rWhale) / Re: Questions about Earthquake Scenario Simulation
« on: April 11, 2024, 10:45:52 PM »
Hi Bofan,

Thanks for using the SimCenter forum.

To better understand the issue. Can you share the "GroundMotions" folder in your SimCenter LocalWorkDir/HazardSimulation folder with me?

Thanks and regards,

Jinyan

Regional Hazard Simulation (R2D, rWhale) / Re: PUENTE HILL MW7.1 SCENARIO (A SCENARIO-BASED SHAKING INTENSITIES)
« on: March 26, 2024, 09:27:11 PM »
Hello,

If you add the three lines at the bottom of this message before Line 295 in the link I sent you in my previous reply, You will be able to set the location of the hypocenter.

Please note that 1. These lines set the location of the hypocenter but not the epicenter. The hypocenter needs to be defined on the fault surface with a depth, and you can add "print(rupSurface.getEvenlyDiscritizedListOfLocsOnSurface().toString())" before Line 295 to check the geometry of the fault surface. 2. The hypocenter defined here is only used by Cambell & Bozorgnia (2014) ground motion models and nowhere else in the backend calculation. If you would like to define the hypocenter for other use, please let us know, and we will see how we can help.

Hope this is clear.

Jinyan

rup = rupList.get(rupture_index)
rup.setHypocenterLocation(Location(33.97, -117.91 , 0))
rupList.set(rupture_index, rup)

Hello,

Thanks for using the SimCenter forum.

Defining the location of hypocenter is not available through editing the configuration Json file, but it is possible by editing the SimCenterBackendApplication python code at https://github.com/NHERI-SimCenter/SimCenterBackendApplications/blob/master/modules/performRegionalEventSimulation/regionalGroundMotion/FetchOpenSHA.py#L295.

However, please note that the GMM selected in your configuration Json file (Boore et al. (2014)) does not use the hypocenter location, and defining the hypocenter location will not make a difference to the predicted ground motions. The only GMM in R2D that uses the hypocenter location is (Campbell and Bozorgnia (2014)). This GMM uses the depth of the hypocenter, and R2D uses the mean of the upper and lower fault edge depth as the hypocenter depth by default. This is reflected in the code linked above and can be edited if you would like to.

I hope this addresses your questions. Should you have any more questions, please don't hesitate to reach out.

Best,

Jinyan

Regional Hazard Simulation (R2D, rWhale) / Re: Error in DL calculation
« on: March 11, 2024, 07:18:41 PM »
Hello Bofan,

This is a flaw of the software that the output format of the earthquake simulation tool is different from the input format of R2D HAZ panel. The earthquake simulation tool uses "SA(0.01)" to represent spectral acceleration at 0.01s, while the HAZ panel uses "SA_0.01" (See the input files of R2D example 14 at https://github.com/NHERI-SimCenter/R2DExamples/blob/master/E14BasicHAZUSTransportation/input_data/IMs/S_001_1000.csv for an example) to represent spectral acceleration at 0.01s.

To resolve this issue, please rename the columns in the output of the earthquake simulation tool so the R2D HAZ panel can read the files.

Thank you for catching this error and we will fix this in the future release. We apologize for the confusion.

Best,

Jinyan

Regional Hazard Simulation (R2D, rWhale) / Re: DATA: Request the sample data of the testbed
« on: February 03, 2024, 06:24:09 PM »
Hello,

The original data (1.84M buildings) described in our San Francisco testbed was produced by our partner, and we are not permitted to share the data. However, SimCenter has produced a similar inventory containing around 1M buildings, and the data is publicly available on DesignSafe at https://doi.org/10.17603/ds2-z5sx-zh27.

Hope this is clear.

Regional Hazard Simulation (R2D, rWhale) / Re: Uncertainty in earthquake scenario simulation
« on: January 21, 2024, 05:46:22 AM »
If the UCERF earthquake rupture forecasting model is used, the uncertainty of the source model is considered in UCERF. For OpenQuake ERF, uncertainty is typically considered with logic trees. However, logic trees are not implemented in R2D now. After earthquake scenarios are generated, R2D uses empirical ground motion prediction equations to generate ground motion intensity measure fields. The uncertainty of GMPEs is considered by modeling the IMs as random fields with distributions as specified in the spatial correlation models. Hope this answers your questions.

Best,

Jinyan

The earthquake hazard scenarios in R2D are generated using either UCERF or OpenQuake. Some details are described at https://nheri-simcenter.github.io/R2D-Documentation/common/user_manual/usage/desktop/R2DTool/tools.html#earthquake-scenario-simulation.

Regional Hazard Simulation (R2D, rWhale) / Re: Incomplete building information
« on: January 21, 2024, 05:36:42 AM »
The minimum building information depends on the types of analysis you would like to perform in the workflow. In general, the minimum building information is the geological location of the building and the information needed to carry out the structural model specified in the MOD panel and the damage and loss model in the DL panel. You could refer to the built-in R2D examples for what information is needed for typical R2D use cases.

Yes, it is possible to select MOD as None and use user-provided fragility.

However, the "IMasEDP" option, instead of "None", should be selected in ANA. Otherwise, R2D will not link the intensity measures to the provided fragility curves.

Regards,

Jinyan

Hello,

This is the maximum distance from the site "centroid" to the source.

Please note the site "centroid" is roughly estimated by taking the average value of the latitude and longitude values of all sites. It is not the geometry centroid of the sites.

Hope this helps.
