If you use this software for your scientific work, we kindly ask you to include a reference [1,2] in your publications. Thank you!

# Installation & Use
## Basic Installation 
Install Loads Kernel as a python package with its core dependencies using a package manager (PyPI or Conda):

```
pip install LoadsKernel
```

or

```
conda install -c conda-forge LoadsKernel
```

## How can I use it?

Copy and adjust the launch script (launch.py, example located in the [scripts folder](https://github.com/DLR-AE/LoadsKernel/tree/master/scripts)) to your needs / for your aircraft configuration. Then, launch the python script with:

```
python launch.py
```

Alternatively, if ~/.local/bin is in your system PATH, you can use the following commands from the command line:

```
loads-kernel --job_name jcl_xy --pre True --main True --post True --path_input /path/to/JCLs --path_output /path/to/output
```

## Advanced Installation 
As above, but with access to the code (download and keep the code where it is so that you can explore and modify):

```
git clone https://github.com/DLR-AE/LoadsKernel.git
cd <local_repo_path>
pip install -e . 
```

To use the graphical tools and other features, optional libraries definded as extras are necessary:

```
pip install -e .[extras]
```

or

```
conda install -c conda-forge loadskernel-extras
```

Note: Especially with mpi or the graphical libraries, pip frequently fails. In that case, try to install the missing/failing packages using a
package manager such as conda, which is the more robust solution.

There are two GUIs to visualize a simulation model (the Model Viewer) and to compare different sets of loads (Loads Compare), which can be started from the command line as well.

```
model-viewer
loads-compare
```
# Tutorials & Examples
There is a growing number of tutorials based on Jupyter notebooks. You can either have a look at the static html tutorials or use the Jupyter notebooks interactively. For the latter, start a jupyter notebook server, which will open a dashboard in your web browser. Then open one of the *.ipynb notebooks from ./doc/tutorials and walk through the tutorials step-by-step.

or

```
jupyter notebook
```

# DLR-Internal Long-Term Continuous Integration

In addition to the public regression testing (see above), additional and more comprehensive tests are performed and compared against long standing reference results. This is an internal process and the status of the continuous integration pipelines can only be accessed from within DLR:
