# EPANET: [PATTERNS]

[PATTERNS]

Purpose:

Defines time patterns.

Format:

One or more lines for each pattern containing:

- Pattern ID label
- One or more multipliers

Remarks:

1. Multipliers define how some base quantity (e.g., demand) is adjusted for each time period.
2. All patterns share the same time period interval as defined in the [TIMES] section.
3. Each pattern can have a different number of time periods.
4. When the simulation time exceeds the pattern length the pattern wraps around to its first period.
5. Use as many lines as it takes to include all multipliers for each pattern.

Example:

[PATTERNS]
;Pattern P1
P1 1.1 1.4 0.9 0.7
P1 0.6 0.5 0.8 1.0
;Pattern P2
P2 1 1 1 1
P2 0 0 1
