Deconstruct Stormwater - [source code]
Turns a stormwater result into meshes and numbers. This is the ONLY component that materialises the field — a run holds millions of values and emitting them all as a tree would freeze the canvas, so ask here for the field and the time you want.
Input
| Name | Nickname | Description | Type |
|---|---|---|---|
| Result | A run from Stormwater Run. | Generic Data | |
| Field | Which field to draw. The (max) fields are peaks over the whole run — what a design is checked against — and are tracked every solver step, so they never miss a peak between snapshots. The (at time) fields read the stored snapshot nearest the Time input. The last three come from the terrain alone and are available from a Fast run. | Text | |
| Time | Minutes from the storm's start, for the (at time) fields. The nearest stored snapshot is used. | Number | |
| Range | Value range mapped onto the colour ramp. Leave unconnected to fit the data. Pin it when comparing two options — otherwise each rescales to its own maximum and the worse one can look identical to the better one. | Domain | |
| Cutoff | Hide cells at or below this value. For a depth field it is in MILLIMETRES, and it is what stops a site-wide film of numerically-zero water from painting the whole model and hiding the ponding that matters. 10 mm is a sensible floor for ponding. | Number |
Output
| Name | Nickname | Description | Type |
|---|---|---|---|
| Mesh | The field as a coloured mesh, one quad per cell. Cells rather than a smooth surface on purpose: the answer IS piecewise constant, and smoothing it would imply a resolution the model does not have. | Mesh | |
| Points | Pts | Centre of every drawn cell. | Point |
| Values | Field value at each point — depth in mm, velocity in m/s, hazard as HR, area in m², slope in m/m. | Number | |
| Colors | Colour at each point. | Colour | |
| Range | The value range actually used, for a legend. | Domain |
