* Increase your 2D cell size. Thanks to SGS the cell size can typically be increased whilst still achieving a good cell size convergence.
* Review your SGS Sample Frequency in the TLF. Typically, a value of 11 or less is all that is necessary to set the SGS parameterisation to a level that achieves excellent accuracy. If the SGS Sample Frequency is excessively large, test reducing the default value by using either the <font color="blue"><tt>SGS Sample Frequency
</ol>
* Inputs might be clipped if their extent is much larger than the code, e.g. grids, material layers and so on. For example if a 100GB DEM is being input to TUFLOW with the majority of the DEM being outside the TUFLOW model, TUFLOW allocates memory to read the entire DEM in for processing. Memory for reading inputs is only used temporarily and is released after the processing of the input, e.g. the DEM.
