Modules

pfc_util.pfc - High-level main module that contains the class pfc.PFC whose instances are PFC models capable of recording and plotting minimization history etc. Save and load models in npz format with pfc.PFC.save() and pfc.load_pfc_model().

pfc_util.core.base - Definitions of PFC free energy functional and state functions. pfc_util.core.evolution - PFC minimizers, including constant chemical potential & nonlocal conserved minimization, stress relaxer and others.

pfc_util.toolkit.static - Static objects access, mostly preminimized solid/liquid profiles. pfc_util.toolkit.routine - Routine high-level utility, e.g. pfc_util.toolkit.routine.find_coexistent_mu() uses binary search to look for solid-liquid coexistence under constant chemical potential.

pfc_util.ortho_lattice_generator - Generates rotated profiles subject to periodic boundary condition.

pfc_util.profile_prompt - Interactive PFC Prompt (WIP).
