COARSENING_MODEL
The model allows you to perform coarsening simulations. Use this command to explicitly set the DICTRA module to use this model.
Enable or disable the use of the simplified model for calculating Ostwald-ripening in multicomponent systems. This also must be used together with the SET_SURFACE_TENSION command.
To use this mode, configure the calculation as follows:
- Have one cell only, with a single particle that is 1.5 times larger than the average particle size.
- The matrix phase should be in contact with the maximum size particle on the left/lower side, and then the model specifies a local equilibrium with an average sized particle on the right/upper side.
- The surface energy then results in growth of both the maximum size particle and the matrix phase. Use SET_SURFACE_TENSION to enter the surface energy to enable coarsening.
