pyTDGL: Time-dependent Ginzburg Landau in Python
pyTDGL is a Python package that solves a generalized time-dependent Ginzburg-Landau (TDGL)
model in two dimensions, enabling simulations of vortex and phase dynamics in thin film superconducting devices of arbitrary
geometry. The package provides a convenient interface for defining complex device geometries and generating
the corresponding finite-element data structures. pyTDGL also includes many methods for
post-processing and visualizing
spatially- and temporally-resolved simulation results.
To get started using pyTDGL see Installation and Quickstart.
