Line 52:
* Double precision might be used, however this would cause models running slower and other measures are recommended to try first.
* Lower 1D timestep can be sensitivity tested, however the timestep should still remain within reasonable bounds. If the 1D timestep is required to be very small for stability reasons, usually other measures can be taken to improve the stability and consequently run time of the model.
* If using TUFLOW Classic, 2D timestep should be between 1/5 and 1/2 of the cell size in metres. Lowering 2D timestep within this range might be beneficial for stabilising
== My model reports very high mass balance error at the beginning, then it lowers. Is it unhealthy? ==
