Line 46:
* Check that a sufficient number of SX cells are selected for the magnitude of the inflows. If it’s a relatively small 2D cell size and a large pit inflow (negative flow) or surcharge (positive flow) is applied to too few SX cells this will may cause instabilities (which is why TUFLOW selects more than one cell at a pit SX if the width of the pit exceeds the 2D cell size). Increasing the number of SX cells may help.
 
=== Notes for all features===
* Use the latest available TUFLOW release.
* Double precision might be used, however this would cause models running slower and other measures are recommended to try first.
