v0.1

The code is functional for solving incompressible fluids problems involving

Boundary conditions:

• doubly periodic
• periodic in x, Dirichlet conditions in z

Spatial discretisation:

• Fourier spectral in both directions
• Fourier spectral in x and finite difference in z

Time stepping schemes:

• Explicit for any discretisation
• Semi-implicit treatment of diffusion operator in fully-spectral only

Compressibility is currently enforced using a vorticity-streamfunction formulation of the Navier-Stokes equations.
