Detailed Description
Sequential solver with exact integration of linear reservoirs.
Each brick is integrated exactly where its outflow is linear in the content (dS/dt = I - q_frozen - k S); the rates of the other processes (e.g. ET) are frozen at their start-of-step value. The resulting volumes are converted to average rates over the step, so the standard constraint and flux machinery applies unchanged.
Compared to the staged explicit solvers, this scheme is unconditionally stable, timestep-insensitive for linear stores, and propagates water through a cascade within the same step (no response lag beyond the physical residence time 1/k).

◆ ComputeBrickRates()

overrideprotectedvirtual |
Compute the average outflow rates of the brick over the time step and store them in the _rates slice starting at iRateStart (one value per process connection, in process declaration order).
- Parameters
-
brick The brick to solve. content Start-of-step content [mm], including instantaneous deposits. inflow Inflows as a constant rate over the step [mm/d]. timeStepInDays The time step in days. iRateStart Index of the brick's first connection in _rates.
Implements SolverSequential.
