| 101 | Modus of volume flow conservation.\\\\ |
| 102 | The following values are allowed:\\\\ |
| 103 | |
| 104 | '' 'default' '' |
| 105 | |
| 106 | Per default, PALM uses '' 'initial_profiles' '' for cyclic lateral boundary conditions ([#bc_lr bc_lr] = '' 'cyclic' '' and [#bc_ns bc_ns] = '' 'cyclic' '') and '' 'inflow_profile' '' for non-cyclic lateral boundary conditions (bc_lr /= '' 'cyclic' '' or bc_ns /= '' 'cyclic' ''). |
| 107 | |
| 108 | '' 'initial_profiles' '' |
| 109 | |
| 110 | The target volume flow is calculated at t=0 from the initial profiles of u and v. This setting is only allowed for cyclic lateral boundary conditions (bc_lr = '' 'cyclic' '' and bc_ns = '' 'cyclic' ''). |
| 111 | |
| 112 | '' 'inflow_profile' '' |
| 113 | |
| 114 | The target volume flow is calculated at every timestep from the inflow profile of u or v, respectively. This setting is only allowed for non-cyclic lateral boundary conditions (bc_lr /= '' 'cyclic' '' or bc_ns /= '' 'cyclic' ''). |
| 115 | |
| 116 | '' 'bulk_velocity' '' |
| 117 | |
| 118 | The target volume flow is calculated from a predefined bulk velocity (see [#u_bulk u_bulk] and [#v_bulk v_bulk]). This setting is only allowed for cyclic lateral boundary conditions (bc_lr = '' 'cyclic' '' and bc_ns = '' 'cyclic' '').\\\\ |
| 119 | Note that '''conserve_volume_flow_mode''' only comes into effect if [#conserve_volume_flow conserve_volume_flow] = ''.T.''. |
