# Baseline Test

## Description

The case tests the combined functionality of the most important Baseline
closures and the functionality of the function object returning the phase
forces.

The test is repeated with inverse phase order in `phaseProperties` to make sure
that the results a not sensitive to this.

## Technical Information

- wedge geometry
- approx. 1000 cells

## Post-Processing

- `phaseForces` function object
- extraction of data along line

## Background

Many simulations rely on the set of Baseline models. Any restriction in
functionality must be detected as early as possible.

In the past, some models produced different results when changing the order of
phases in `phaseProperties`: turbulent dispersion changed sign (producing anti-
diffusion instead of diffusion) and induced turbulence model received incorrect
blending factors (causing a significantly different turbulence level). This was
fixed. The robustness against the phase order should be ensured in future.
