Because pumps are zero length channels they do not create automatic nodes at the upstream and downstream end. If you ran the model with just a pump polyline you will get ERROR 1353 - No NA data for Node. To remove this error you will need to digitise a node within a separate 1d nwke layer and give a nominal storage amount in the “Len_or_NA” attribute for the 1d nwke ‘Node’, see the example below.<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>
* [[QGIS_Style_Check_Files | QGIS style check files]]
* [[MapInfo_Style_Check_Files | MapInfo style check files]]
* [[ArcMap_Style_Check_Files | ArcMap style check files]]
=1D-2D Configuration=
Connecting a pump from a 1d network to the 2d domain or vice versa is similar to the configuration above, the only difference is that the connection with a 1d structure does not require a 2d SX connection or 1d nwke ‘Node’. A storage chamber in the 1d network can also be modelled using a 1d_na node with an elevation vs area .csv assigned to the node. <br>
