TUFLOW Message
CHECK 3506: Limiting SGS Grid sample frequency to upper limit of 'a'., sample distance of 'b'.
Alternate Message
N/A
Message Type
CHECK
Description
Too high SGS sample frequency can result into long pre-processing time, and users may not benefit from applying a super fine sample distance against the model cell size. In general we found a sample frequency smaller than 31 is sufficient for most of natural water ways or artificial structures, and the default frequency limit is set as 31.
Suggestions
The default limit can be changed by using a second argument in the SGS Grid/TIN Sample Distance command, e.g. SGS Grid Sample Distance == 1 I 50 sets the sampling distance to 1 m and the frequency limit to 51 for grids.
