1D Pumps: Difference between revisions

=Introduction=

This post provides a modelling example for a 1D pump using a fixed flow rate and pump curve. For this example we will model a pump in two common situations (2D-2D & 1D-2D).

The 2D and 1D check files can be controlled separately by having the <font color="blue"><tt>Write Check Files </tt></font> <font color="red"><tt>==</tt></font> in both the .tcf and .ecf files. However,

<font color="blue"><tt>Write Check Files </tt></font> <font color="red"><tt>==</tt></font> in the .tcf file will automatically also write the 1D check files. There is no need to specify <font color="blue"><tt>Write Check Files </tt></font> <font color="red"><tt>==</tt></font> in the .ecf file unless a different folder path for the files is desired.<br>

To output only the gridded elevations (DEM_Z) the command would be :<br>

<font color="blue"><tt>Write Check Files Include </tt></font> <font color="red"><tt>==</tt></font><tt> DEM_Z</tt><br>

Depending on the size of the model, the check files may contain a large amount of data, for example the _grd_check file may contain thousands or millions of cells. As a modeller you probably won't inspect each cell to ensure that the data is value, however you may want to view this for the entire model. Thematic mapping or styling the input layers can be used in your GIS software to do this.

Some tips are given below for a range of GIS platforms, however, the functionality is likely to be available in almost all GIS platforms:<br>

* [[MapInfo_Style_Check_Files | MapInfo style check files]]

* [[ArcMap_Style_Check_Files | ArcMap style check files]]

The check files are separated into 2D and 1D check files. The output location for these is controlled by commands in the .tcf and .ecf as described above. Not all check file types will be output for all models, if a model has no 2D Z Shape (2d_zsh) format topography modifiers then the _zsh_zpt check file type will not be output by TUFLOW. A list of the check file types is provided below. For more information on each of these please click on the page link.<br>

It is also worth noting that the attributes of the check file may also change depending on the features in the model. If a model has soils specified (for infiltration) then the _grd_check file will contain the soil type for each grid cell. If no soils are specified this attribute is not output.<br>
