AI use in Regional Simulation (BRAILS) / Re: NotImplementedError
« on: November 09, 2021, 12:37:07 AM »
Let us start with identifying the example are you trying to run?
Can you post the link to the webpage, and if more than 1 example is posted there, can you identify the specific example.

Wind Engineering (WE-UQ) / Re: Selecting version of OpenFOAM in WE-UQ
« on: October 22, 2021, 11:16:22 PM »
That is TinF, which is different to WE-UQ. I have asked the developer how much effort to move to OpenFOAM7. I know there are libs that are compiled from our code (TinF and possible others) that are used by OpenFOAM, just not sure if they will compile for 7 and if they do not, what effort will be required. It is Friday afternoon, hopefully get back Monday.

Wind Engineering (WE-UQ) / Re: Unable to select pimpleFoam in WE-UQ

I have updated WE-UQ for windows. That option should be now available. Version should say 2.2.0

Can you confirm what version you are running as it should be in version 2.2.0. If you are running v2.2.0 can you confirm what operating system you are using and I will test on that OS. thanks and sorry for the confusion

looking at the wrapper script that runs at TACC it only load the openfoam 6.0 module.

1) can you point out where in the doc it says 7.0 so i can fix that
2) is there something you need in 7.0?

Performance Based Engineering (PBE) / Re: Error In building PBE source code
« on: October 11, 2021, 05:33:33 AM »
The curl code is not included in the released software (there are other software packages we use as well that we do not release as they are released by others). Curl is however installed by the conan package manager before cmake is run (if interested curl and the other software we use are listed in the conanfile.py).

mkdir build
cd build
conan install .. --build missing
qmake ../PBE.pro
make

if on a windows machine, use nmake instead of make. let me know if it does not work for you.

1. yes a street view like image
2. it is a binary classifier that was trained using images of buildings on stilts versus buildings on the ground, see sample images here: https://nheri-simcenter.github.io/BRAILS-Documentation/common/user_manual/modules/foundationElevationClassifier.html

now we do have a module about to be released (October 2021) that provides a calculation of height of first floor level above the soil that goes beyond the image classifiers. It is part of BRAILS being developed at UCLA to determine needed info (roof pitch, roof elevation, first floor level). We have used the software in our testbeds to provide this information for our regional inventories.

Rashad,  DesignSafe is down till Monday (20 Sept 2021) now. The executables because of their size are kept there.

Thanks for the question. You point out a weakness in the documentation which I will work to get improved.

The soft story model is an image classifier that utilizes a convolution neural network (CNN). Like the roof classifier and occupancy classifier, the training and test sets for the CNN used a collection of labelled images. The image sets for the soft story classifier consists of a set of street-view photos of buildings that were labelled as either being a soft story or not a soft story (with many of the labels being obtained from lists of weak story buildings obtained online, e.g. Santa Monica (https://www.arcgis.com/apps/webappviewer/index.html?id=05191306d93d4c04827773b8d2151cd7), Berkeley (https://www.cityofberkeley.info/softstory/) and others). 

For a more generic under standing of CNN's use in image classification see: https://developers.google.com/machine-learning/practica/image-classification

Better approaches to detecting soft stories are indeed possible that could include for example detecting floor levels and performing calculations as you suggest.

Can you be a bit more specific, for example are you looking at the different individual BRAILS modules or are you using CityBuilder.  You might want to look at day 1 of the material presented for a recent workshop that SimCenter gave in which image classification is discussed:

https://nheri-simcenter.github.io/SimCenterAI_Workshop2021/source/lecture_videos.html#day-1-introduction-to-machine-learning-part1-2-and-part3-and-brails

There is no manual processing of images to create images used in CityBuilder when they are downloaded from Google. What a user using the individual modules does to their images before they use any of the modules in BRAILS is up to the user; we don't do any manual processing.

Earthquake Engineering (EE-UQ) / Re: Random variables of a database in EE-UQ
« on: August 17, 2021, 07:46:04 PM »
it is not possible with what is currently released. it is planned in the next release (due end Sept) when we will include more of the functionality of quoFEM in EE-UQ.

Depending on what you are doing with the earthquake selection, you might be able to use quoFEM now, to do what you want.
