|message_desc= The sub-grid sampling of materials (land-use) was first introduced in the 2020-10 Release as beta functionality. However, feedback and further testing indicates that additional development is required. Some significant issues have been identified including the large dynamic range in face depths over which the look-up table must be computed, the transition between sheet flow and channel flow, and the inclusion of the effects of eddy viscosity or sub-grid turbulence on the parallel flow analysis. The latter issue in particular needs further research to provide consistency between different cell sizes.
|message_desc= If SGS Materials are on in combination with depth varying Manning’s n value error is issued and the simulation stops. If SGS Materials is enabled without depth varying Manning’s n values warning is issued.
<br>
This feature is still available in the 2022 release, however, changes in results will occur when compared to 2020 release due to feature updates.
|suggestions=Turn off SGS materials if depth varying Manning’s n is used. Check the use of SGS materials is intentional when depth varying Manning’s n is not used and review results.
