# Test Case for Disintegration To Continuous Morphology Transfer Model

## Description

This test case refers to the phase inversion problem of oil in water in a 2D
square box[^1]. Water and oil are both located in a closed box. Initially, the
oil is purely represented as continuous phase. After disintegration of the
continuous oil structure, the oil is transferred to a phase of disperse
morphology. The vice-versa process is allowed, when the oil accumulates at the
top part of the domain.

## Technical Information

- continuous phases: water, oilC
- disperse phase: oilD
- phase change:
  - from oilC to oilD (disintegrationToDisperse)
  - from oilD to oilC (accumulationToContinuous)
- 2D
- 20x20 cells
- no turbulence, no wall force

## Pre-Processing

Phases are initialised with setFields.

## Post-Processing

A `createGraphs` script is available in the validation directory.

Total volume of all three phases is stored via the volFieldValue functionObject.
