+# BouncingBall
+
+The BouncingBall implements the following equation:
+
+```
+der(h) = v
+der(v) = -g
+
+when h <= 0 then h := 0 and v := -e * v
+when v < v_min then h := 0 and v := 0
+```
+
+whith the variables
+
+| Variable | Start | Unit | Causality | Variability | Description
+|:---------| -----:|:-----|-----------|-------------|:---------------
+| h | 1 | m | output | continuous | Distance to the ground
+| v | 0 | m/s | output | continuous | Velocity
+| g | 9.81 | m/s2 | parameter | fixed | Gravity
+| e | 0.7 | | parameter | tunable | Rebound factor
+| v_min | 0.1 | m/s2 | parameter | constant | Threshold velocity to stop bouncing
+
+The plot shows the [reference result](BouncingBall_ref.csv) computed with [FMPy](https://github.com/CATIA-Systems/FMPy).

+## Using the issue tracker
+
+The issue tracker is the preferred channel for [bug reports](#bug-reports), [features requests](#feature-requests) and [submitting pull requests](#pull-requests).
+Please **do not** use the issue tracker for personal support requests.
+[Stack Overflow](http://stackoverflow.com) is a better place to get help.
+
+## Bug reports
+
+A bug is a _demonstrable problem_ that is caused by the code in the repository.
+Good bug reports are extremely helpful - thank you!
+
+Guidelines for bug reports:
+
+1. **Use the GitHub issue search** — check if the issue has already been reported.
+
+2. **Check if the issue has been fixed** — try to reproduce it using the latest `master` or development branch in the repository.
+
+3. **Isolate the problem** — create a reduced test case or example.
+
+A good bug report shouldn't leave others needing to chase you up for more information.
+Please try to be as detailed as possible in your report.
+What is your operating system, FMI version and type, importing tool?
+What steps will reproduce the issue?
+What model experiences the problem?
+What would you expect to be the outcome?
+All these details will help people to fix any potential bugs.
+
+Example:
+
+> Short and descriptive example bug report title
+>
+> A summary of the issue and the platform/OS environment in which it occurs. If suitable, include the steps required to reproduce the bug.
+>
+> 1. This is the first step
+> 2. This is the second step
+> 3. Further steps, etc.
