# Instructions

I had a few minor issues getting the instructions to produce the expected output. Bellow are the corrections needed:

‌

1. In step 3, instruction 1 where one reads

```
./utils/Scripts/MakeThornList --master thonrlists/einsteintoolkit.th --output thornlists/Kerr-Schild_Multipole.th
```

one should read

```
./utils/Scripts/MakeThornList --master thornlists/einsteintoolkit.th --output thornlists/Kerr-Schild_Multipole.th par/Kerr-Schild_Multipole.par
```

2. In step 4, where one reads

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

one should read

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

# Visualization

I recommend removing the `wget http://einsteintoolkit.org/gallery/multipatch/Kerr-Schild_Multipole.session` file from the gallery for the following reasons:

1. In `visit` version `3.4.1`, where I produce the plots, several instructions on the session file are deprecated.
2. The session file is highly specific to the user that tested the visualization. Any changes in input, output and home folders cause the session to fail

I propose that instead of using the session file, we provide a python script to produce the output. The script increases reproducibility of the example and addresses both issues mentioned above and can be invoked via

```
visit -cli -nowin -s plot.py <Folder containing Carpet HDF5 files> <Output folder> <image name (without extension)>
```

‌

How would I go about changing this @Roland Hass?
