Results are available for Permeable Zones (2D) objects.
All results fields are displayed on the results grid and on the network results Property Sheet while viewing a replay of a simulation.
Time varying results are shown with the field name in an alternate colour on the grid. Non-time varying results have the field name in the normal black type.

|---|---|---|---|---|
| AVGINFRATE2D |
Average infiltration volume rate. Calculated as (CUMINFVOL2D(t+1)-CUMINFVOL2D(t)) / (results_timestep) |
Q | AVGINFRATE2D | True |
| CUMINF2D |
Cumulative infiltration. Calculated as CUMINFVOL2D / (Area of Permeable Zone 2D object in m2) |
Y | CUMINF2D | True |
| CUMINFVOL2D | Cumulative infiltration volume. | VO | CUMINFVOL2D | True |
| INFVOLRATE2D | Instantaneous infiltration rate.
This rate provides a value at a specific timestep rather than the average value between reporting timesteps. In some cases, these timesteps are very small, especially before a major save/gauge timestep, and can produce unrealistic results at a particular timestep, which may appear as spurious spikes in graphs. For example: 
|
Q | INFVOLRATE2D | True |
| MAXINFVOLRATE2D | Maximum instantaneous infiltration rate. | Q | MAXINFVOLRATE2D | False |
| MININFVOLRATE2D | Minimum instantaneous infiltration rate. | Q | MININFVOLRATE2D | False |
| Area in 2D Zone |
The actual area of the 2D elements associated with the Permeable Zone (2D) used by the simulation engine to perform the calculations. Each permeable zone has an Area property however, this area may not be the same as the one included in the calculations if the:
