MedeA Interface Search

MedeA's novel interface search algorithm and building capability lets you determine heterogeneous interfaces and grain boundaries.

The interface search is based on geometrical matching criteria to find  coherent lattices for interface components with differing lattice parameters. The procedure allows you to smoothly adapt lattice parameters for components with differing hardness.

For elements, grain boundaries are determined as having a natural perfect lattice match for certain embedding angles.

The interface search provides a spreadsheet of structural solutions matching the starting conditions and lets you build selected candidates and further refine by adjusting the interface gap and gamma surface orientation.

Key Features

• Finds heterogeneous interfaces and grain boundaries
• Automatic search for interfaces with minimum misfit
• Graphical preview with symmetry analysis
• Adjust individual interface gaps and in-plane orientation (gamma surface degrees of freedom)
• Split an interface into the corresponding free surface systems
• Full integration with MedeA's builders and computational tools.
