Pressure filter and pressure gradient computed so that boundary conditions can be used. Everything is limited to a single block.

Velocity formulation with filtered pressure and handmade periodic boundary conditions. WORKS ONLY WITH ONE BLOCK! No other boundary conditions.

Velocity fomulation without viscosity correction and no output for pressure and wrong output for velocity
