Description
Too high SGS sample frequency can result in 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 31 (per face).
The minimum limit of SGS sample frequency is 3. Anything below that will be adjusted to 3.

Suggestions
The default limit can be changed by using the .tcf command SGS Max Sample Frequency ==". Note, a hard limit of 127 per face still applies.
Please refer to the TUFLOW Manual for more information.
