#2174: Test "Multi Patch Scalar Wave Equation" example

Reporter: Roland Haas Status: open Milestone: ET_2024_11 Version: development version Type: task Priority: major Component: EinsteinToolkit website

Changes (by Roland Haas): Before each release, check that http://einsteintoolkit.org/gallery/multipatch/index.html still works and produces correct output.

**Steps**:

1. download the _development_ version of the Einstein Toolkit:

```shell curl -kLO https://raw.githubusercontent.com/gridaphobe/CRL/master/GetComponents chmod a+x GetComponents ./GetComponents https://bitbucket.org/einsteintoolkit/manifest/raw/master/einsteintoolkit.th ```

2. download the parameter file fro the gallery example

```shell cd Cactus wget --output-document par/Kerr-Schild_Multipole.par https://bitbucket.org/llamacode/llama/raw/master/LlamaWaveToy/par/Kerr-Schil... ```

3. compile Cactus for the system you are on (this may require that you add a cluster allocation etc.)

```shell ./utils/Scripts/MakeThornList --master thornlists/einsteintoolkit.th --output thornlists/Kerr-Schild_Multipole.th par/Kerr-Schild_Multipole.par ./simfactory/bin/sim setup-silent ./simfactory/bin/sim build --thornlist thornlists/Kerr-Schild_Multipole.th ```

4. run the simulation, using number of MPI ranks similar to what is shown on the ET website, so _for example_

```shell ./simfactory/bin/sim create-submit Kerr-Schild_Multipole --parfile par/Kerr-Schild_Multipole.par --cores 8 --num-threads 2 --walltime 0:30:00 ```

5. on your laptop install VisIt using the precompiled executable available from its [download page](https://visit-dav.github.io/visit-website/) 6. comprehensive instructions on how to produce the images are on the [gallery page](http://einsteintoolkit.org/gallery/multipatch/index.html )

**Data to upload**

1. Data is made available at [https://bitbucket.org/einsteintoolkit/www/downloads/%5D(https://bitbucket.or...) and you should see a blue “Add Files” button in the top right, when logged in with your Bitbucket account. If that is not the case contact the release manager to have you added. 2. The data file is named Kerr-Schild_Multipole-YYYYMMDD.tar.gz and should contain the files required to reproduce the plots as well as parameter files, stdout and stderr files and the plot scripts. As of this writing this are the files `u.file_*.h5`, `x.file_*.h5`, `y.file_*.h5`, `z.file_*.h5`, `Kerr-Schild_Multipole.par`, `Kerr-Schild_Multipole.out`, `Kerr-Schild_Multipole.err`, `plot.py`, `Kerr-Schild_Multipole.session`. 3. uploading the file with a browser can be troublesome and fail with no apparent error message. Instead using `curl` and bitbucket’s [REST API ](https://developer.atlassian.com/bitbucket/api/2/reference/resource/repositor... be used.

1. If you have enabled TFA for Bitbucket, then you can use an Application password with write permission to the repo. These can be created here: [https://bitbucket.org/account/settings/app-passwords/%5D(https://bitbucket.o...) 2. Then run (replace the file name and the user name and password with the appropriate values):

``` curl -u YOURBITBUCKETUSERNAME:YOURBITBUCKETPASSWORD -X POST https://api.bitbucket.org/2.0/repositories/einsteintoolkit/www/downloads -F files=@Kerr-Schild_Multipole-YYYYMMDD.tar.gz ```
