Project `PFDEM_ACS_MG`

Phase-Field Discrete Element Modelisation with solute generation applied to multiple grains.
The goal is to simulate the pressure solution phenomena to granular material with multiple grains under oedometric conditions.
Scheme of the pressure-solution between 2 grains
Scheme of the model: oedometer
One movie of an example
