## Setup

This tutorial solves the same problem as the oscillator tutorial, but applies a different domain decomposition strategy. See the oscillator tutorial for details on the general setup. The partitioning of the mass-spring system is shown here:

Note that this case applies an overlapping Schwarz-type coupling method and not (like most other tutorials in this repository) a Dirichlet-Neumann coupling. This results in a symmetric setup of the solvers. We will refer to the solver computing the trajectory of $m_1$ as `Mass-Left`

and to the solver computing the trajectory of $m_2$ as `Mass-Right`

. For more information, please refer to [1].

## Available solvers

This tutorial is only available in Python. You need to have preCICE and the Python bindings installed on your system.

*Python*: An example solver using the preCICE Python bindings. This solver also depends on the Python libraries`numpy`

, which you can get from your system package manager or with`pip3 install --user <package>`

.

## Running the Simulation

### Python

Open two separate terminals and start both participants by calling:

```
cd python
./run.sh -l
```

and

```
cd python
./run.sh -r
```
