This pages contains information on the attributes of the _grd_check file. This GIS contains each active (cell code 1) or null (cell code -1) cell. A number of the output attributes are only written if certain model features are enabled. For example, the SRF (Storage Reduction Factor) attribute is only included if any SRF commands are used in the model.
Attributes of grd_check
| Attribute Name | Attribute Description |
|---|---|
| n | Row number in the TUFLOW domain |
| m | Column number in the TUFLOW domain |
| Code | The cell code status. This is 1 for active cells. |
| Material | The material ID. |
| ZC | The cell centre elevation. |
| IWL | The initial water level value. |
| Domain_Index | The index of the model domain. This is the order with Start 2D Domain == <Domain Name> commands appears in the .tcf control file. For a single domain model this will be 1. |
| Mann_n (GPU model only) | The Manning's n value for the cell. This is only output for a GPU model only as the GPU model is a cell centred scheme and the Manning's n value is applied at the cell centre. For a TUFLOW "classic" simulation the Manning's is applied at the cell side and this is output in the _uvpt_check.mif _uvpt_check_P.shp |
| FLC (GPU model only) | Form loss coefficient, tThis is only output for a GPU model only as the GPU model is a cell centred scheme and the FLC value is applied at the cell centre. For a TUFLOW "classic" simulation this is applied at the cell side and this is output in the _uvpt_check.mif _uvpt_check_P.shp |
| CWF_x (GPU model only) | Cell width factor in the x-direction. This is only output for a GPU model only as the GPU model is a cell centred scheme and the CWF value is applied at the cell centre. For a TUFLOW "classic" simulation this is applied at the cell side and this is output in the _uvpt_check.mif _uvpt_check_P.shp |
| CWF_y (GPU model only) | Cell width factor in the y-direction. This is only output for a GPU model only as the GPU model is a cell centred scheme and the CWF value is applied at the cell centre. For a TUFLOW "classic" simulation this is applied at the cell side and this is output in the _uvpt_check.mif _uvpt_check_P.shp |
| SRF (only if SRF feature used) | The Storage Reduction Factor for the cell. |
| Soil_ID (only if soil feature used) | The Soil ID for the cell. This is only output if a Set Soil, Read GIS Soil or Read GRID Soil command is specified for the simulation. |
This file is very useful to apply a style or thematic map to. See the Tips for visualising check files page.
An example of a grid check file shaded by Material ID is below. This allows a very easy way to visualise the final properties for large models.
