Ising_OPV v2.0

This software tool is used to generate and analyze model bulk heterojunction morphologies in a parallel computing environment. Version 2.0 adds several exciting new features and contains several major performance improvements from v1.0.

Major New Features:

• Controlled interfacial mixing following phase separation can now be performed.
• Several advanced morphology characterization procedures that calculate interfacial distance histograms, tortuosity histograms, end-to-end paths, island volume fraction, and interfacial volume fraction.
• Users can enable periodic boundary conditions in the z-direction.

Performance Improvements:

• Output morphology file can now be created using a compressed format that dramatically reduces disk space usage.
• Domain size calculation speed has been greatly increased resulting in a significantly lower overall calculation time when creating morphologies with large domain sizes.
• Memory usage reductions increase the maximum lattice size possible.

Removed Features:

• Ability to specify a target domain size has been removed do to the challenge in performing a satisfactory estimate for the wide variety of possible input parameters.

Additional Updates:

• Users can now test the effect of asymmetric interaction energies.
• Simplified morphology import.
• More complete code commenting.
• Improved smoothing algorithm that reduces blocky artifacts when using a large rescale factor.
