Title: Share quoFEM examples here (user-to-user file sharing)
Post by: Sang-ri on March 01, 2022, 12:06:32 AM

Users of quoFEM are welcome to share their example files by replying to this post.

• Contributor
• Option 1
• Click [reply] button to share
• Requirement: A single zipped folder that contains all the required files and data (if any) along with the quoFEM input file (.json file)^*
• Requirement: A brief summary of the analysis
• Requirement (if any): Special instruction to run analysis, eg. need a license of a FEM software
• Recommended: Information on how to cite this work
• Recommended: A detailed description of the model or references to literature detailing the model
• Recommended: Expected runtime of the whole analysis, ie. how long are the users expect to wait after clicking the run button (eg. several seconds, minutes, hours, days)
• Option2
• Upload your files and description to another platform (eg. DesignSafe data depot or GitHub) and post the link here. We believe this option will help the users of your files to give stronger credit to your work. For example, DesignSafe allows you to formally publish a simulation model by providing a Digital Object Identifier (DOI) number.


• User : Unzip the folder, find and load the quoFEM Input file (.json file), hit the run button (Unless differently instructed by the contributor).

* Note: quoFEM Input file (.json file) can be saved by clicking [file-save as] button at the quoFEM menu bar. Make sure to save the Input file (.json) directly in the folder where your FEM inputs are located, and not copy it after saving it in another directory (this is to have relative file paths). See quoFEM\Examples\qfem-0001\src folder or other example folders to see how an example can be shared as a single folder.

The files shared in this post pertain to using quoFEM to conduct global sensitivity analysis and Bayesian calibration of a liquefaction-capable material model available in OpenSees, and probabilistic prediction of lateral spreading due to seismic soil liquefaction employing the calibrated material model.

On unzipping the attached folder, there will be three directories, each of which contains all the files necessary to run an analysis in quoFEM. The shared files have been tested on quoFEM Version 3.1.0

Refer to the attached preprint for a detailed description of the problem and the models used. Citation information will be provided once available.

Each model evaluation during the sensitivity analysis and calibration phase takes about 1 minute. Each model evaluation for predicting the lateral spreading takes about 20 minutes to complete. (Runtimes on a 2020 MacBook Pro with 2 GHz Intel Core i5 processor with 32 GB memory).
