This package contains some simple tools for writing fluid-dynamics solvers using pseudo-spectral methods. The basic structure of the package is closely patterned on the spectral DNS code of Mortensen and Langtangen, which can be found here and is described here. That package requires a substantial software stack, and is built on a generic spectral Galerkin package, which makes it more difficult to tinker with. This package is designed to be a transparent and easy to modify as possible, for use as a research code.
Example scripts can be found in the examples directory.
