 Switch to steer the call of the pressure solver.\\\\
-In order to speed-up performance, the Poisson equation for perturbation pressure (see [#psolver psolver]) can be called only at the last substep of multistep Runge-Kutta time step schemes (see [#timestep_scheme timestep_scheme]) by setting '''call_psolver_at_all_substeps''' = ''.F.''. In many cases, this sufficiently reduces the divergence of the velocity field. Nevertheless, small-scale ripples (2-delta-x) may occur. In this case and in case of non-cyclic lateral boundary conditions, the default value '''call_psolver_at_all_substeps''' = ''.T.'' should be used.

+Pressure solver must be called at each RK3 substep when [#momentum_advec momentum_advec] = 'ws-scheme'.
