Message Type
ERROR

Description
These commands/functions are not supported in either SGS or Quadtree (depending on the message received) with the used TUFLOW version.
If the message received is "ERROR 3517 - "Read RowCol Zpt" not supported with Quadtree" this is because the GIS layer is cell size dependent and cannot be used in a Quadtree model, as they have multiple cell sizes.
If the error is ERROR 3517 - "Read RowCol Zpt" or "Read MID Zpt" not supported in SGS", this error occurs as reading data in this format only reads the cell centre (zc), cell face (zu and zv) and cell corner (zh) elevations. Data read in RowCol are read based on the model row and column reference and does not account for sub grid sampling within a cell. This command was made redundant with the addition of direct reading of raster grids and TIN files in the 2011 version of TUFLOW.
Note: "Read RowCol Zpt" and "Read MID Zpt" are treated identically in TUFLOW with "Read MID Zpt" being the syntax for versions prior to 2010 when GIS formats were extended to include Shapefile.

Suggestions
Use the latest version of TUFLOW available from the TUFLOW website. Alternatively, remove these features to run in SGS (or Quadtree depending on the message).

If the message received is "ERROR 3517 - "FC" not supported yet in SGS" this is because a GIS 2d_fcsh layer is used. Change this to a 2d_lfcsh layer which is supported when using SGS.

If the message received is "ERROR 3517 - "Read RowCol Zpt" not supported with Quadtree" or "ERROR 3517 - "Read RowCol Zpt" not supported in SGS" use the source elevation layer that the file was originally generated from. This can be replaced with "Read Grid Zpt" if using a raster grid, or "Read TIN Zpt" if using a TIN surface.

Alternatively, if you have both .mid/.mif it is possible (although not recommended) to generate a raster within QGIS which can be read into TUFLOW instead. If there is no .mif file, this can be generated in TUFLOW using the following in the TGC (anywhere the zpt layer is not 99 will be the original sample points and elevations). Note that SGS must be switched off for this model run to get the .mif file created:
Set Zpts== 99
Read MID Zpts== input_file.mid
Write GIS Zpts== output_file.mif !or .shp, .gpkg
Stop
