About the Grain Boundary Model (GB_Model)

This section or topic is specific to Console Mode.

You must explicitly set the DICTRA module to use this model with GB_MODEL. This model allows you to simulate grain-boundary and dislocation-assisted diffusion.

The grain boundaries and the dislocations contribute to the total amount of diffusion according to the weighted fractions. The parameters are entered separately for each region in order to allow for different expression for different phases.

See the TCNI Examples Collection - Isothermal Solidification During Brazing: A Diffusion Simulation for an example using this model.
