ShellBenchmarking.jl

Illustration of the proposed test suite from the paper "BENCHMARKING COMPUTATIONAL SHELL MODELS" by Krysl and Chen (2022), published in the Archives of Computational Methods in Engineering. The general flat-facet shell finite element T3FF is used.

A preliminary version of the manuscript is available as a PDF.

Instructions for those new to Julia

We are assuming that your computing platform is Windows. The naming of the folders and a few other details are different on Linux or the Mac.

1. Click on the latest release. Download as .zip file. Unzip the folder somewhere. Let us say it is in the Downloads folder: C:\Users\YourUserName\Downloads\ShellBenchmarking.jl-0.3.0.
2. Download Julia. Go to https://julialang.org/downloads/, and choose the portable current stable release. Download to the same folder (Downloads). Extract the zip file (for instance with 7-zip choose "Extract here"). This will yield C:\Users\YourUserName\Downloads\julia-1.7.1 (for instance).
3. Change your working folder to the C:\Users\YourUserName\Downloads\ShellBenchmarking.jl-0.3.0 folder.
4. Start a cmd window. Make sure that the folder displayed in the command window is C:\Users\YourUserName\Downloads\ShellBenchmarking.jl-0.3.0.
5. Start julia in a cmd window by running the command ..\julia-1.7.1\bin\julia.exe.
6. When you get the Julia prompt, julia>, run the following commands (copy and paste into the command window)

include("top.jl")
using Pkg; Pkg.test(); 

First, the environment is set up, and then the second line executes the tests of the shell formulation.

Have a look at the Results section below.

Quick instructions for Julia users

Assuming the ShellBenchmarking.jl package was cloned from Github, change your working directory into the ShellBenchmarking.jl folder, start julia, and then run

include("top.jl")

To produce the results presented in the paper, execute

using Pkg; Pkg.test(); 

Have a look at the Results section below.

Results

The test directory will hold the generated files, .vtu files for visualization with Paraview, and .pdf files for the generated graphs. Beware: running the above will first clean all the output files from the previous run.

Details

The runtests.jl script in the test folder shows which examples are executed in the tests. These are all files ending in _examples.jl. Feel free to browse the source code in these files.

The functionality of the shell finite element is provided by the package FinEtoolsFlexStructures. The implementation may be inspected there.
