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

Reporter: Roland Haas Status: open Milestone: ET_2023_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 thonrlists/einsteintoolkit.th --output thornlists/Kerr-Schild_Multipole.th ./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 --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. get the VisIt session file

```shell wget http://einsteintoolkit.org/gallery/multipatch/Kerr-Schild_Multipole.session ```
