Simulation Conditions

Choose the Default solver: Automatic or Homogenization. Select Homogenization to define the Homogenization Model Specific sections.

Classic and Homogenization Model Settings

The homogenization solver (called the homogenization model in Console Mode) is useful when you want to simulate long-range diffusion through a multiphase mixture, under the assumption that local equilibrium holds at each node point.

Automatic , Trapezoidal, or Euler backwards.

The default is Automatic where the default degree of implicity corresponds to trapezoidal (0.5) for classic and Euler Backward (1.0) for the homogenization model. If large fluctuations occur in the profiles it may be necessary to use the more stable but less accurate Euler backwards.

Yes, No, or Every nth.. Select Every nth to enter a value in the field.

This setting determines if the results are to be saved on file during the course of the simulation. Select:

• Yes to always save on file.
• No to never save on file.
• Every nth. to save every n^th time to file. Then enter an integer value ranging from 0 to 99.

The default, Automatic, allows the software program to automatically use forced starting values to perform the equilibrium calculations. When a phase with an ordering contribution is entered into the simulation, for example the gamma-prime/FCC_l12 phase in Ni-base superalloys, forced starting values are automatically turned on. Or choose Yes or No.

Enter a value in the field. The required driving force (evaluated as DGM (ph)) to be used for determining whether an inactive phase is stable. DGM is the variable for the driving force that is already divided by RT, and it is dimensionless. The default is 1E-5.
