timeinputmodulo

timeinputmodulo

Returns a map for each timestep using a modulo index into a shorter map stack.

Result = timeinputmodulo(SuffixMap, highestTimestepAvail)

SuffixMap

boolean, nominal, ordinal, scalar, directional, ldd, spatial, non spatial

highestTimestepAvail

ordinal, non spatial

Result

type of SuffixMap, spatial

Operation

Works like the timeinput except that in timesteps larger than highestTimestepAvail a stack item I is read according to the formula:

m = time() mod highestTimestepAvail

I = if (m eq 0, then highestTimestepAvail else m)

Notes

highestTimestepAvail must be a single integer and cannot be a computed variable.

Example

A dynamic modelling script with 7 timesteps contains the function:

rainFall = timeinputmodulo(rain,3);

The maps assigned to rainFaill are as follows:

in timestep	map
1	rain0000.001
2	rain0000.002
3	rain0000.003
4	rain0000.001
5	rain0000.002
6	rain0000.003
7	rain0000.001
