About the Disperse Model
This section or topic is specific to Console Mode.
This model can be used to calculate diffusion of a phase that is dispersed in a matrix phase. However, it is recommended that you use the
There is no specific command to activate this model. It is only available if a phase of type "spheroid" is entered in a region.
The disperse model has the following limitations:
- There must be a continuous matrix phase otherwise the simulation breaks down.
- There is no implicit integration of the partial differential equations (PDEs), leading to a lower accuracy.
-
Only diffusion in the matrix phase can be simulated. It is assumed that no diffusion occurs in the dispersed phase.
After a spheroid phase is entered, the homogenization model must explicitly be inactivated in order to run the simulation with the dispersed model. To do this, enter the command HOMOGENIZATION_MODEL and then choose N to make it inactive.
