whirly 1.0.1

Spectral solutions to two-dimensional PDEs.

whirly

whirly provides easy-to-use Python classes for the spectral solution of two-dimensional partial differential equations, especially those related to fluid dynamics. The core of the package is the abstract PseudospectralSolver class, which is easily extensible to a variety of PDEs with linear and nonlinear terms. For time stepping, whirly implements a fourth-order integrating factor method as outlined in Yang et al. (2021), accessible through the IFRK4Integrator class.

See example.ipynb for a quick demonstration of whirly used to solve the two-dimensional vorticity equation.

whirly can be installed with pip install whirly.
