| 218 | Top boundary condition of the perturbation pressure.\\\\ |
| 219 | Allowed values are '' 'dirichlet' '' (p(k=nz+1)= 0.0) or '' 'neumann' '' (p(k=nz+1)=p(k=nz)).\\\\ |
| 220 | Simultaneous use of Neumann boundary conditions both at the top and bottom boundary ([#bc_p_b bc_p_b]) usually yields no consistent solution for the perturbation pressure and should be avoided. Since at the bottom boundary the Neumann condition is a good choice (see [#bc_p_b bc_p_b]), a Dirichlet condition should be set at the top boundary. |
