TUFLOW Geometry Control File (TGC)

The TUFLOW Geometry Control File (TGC) contains a series of commands that build the 2D geometry model. At its minimum, the TGC contains:

  • Information on the size and orientation of the grid;
  • Grid cell codes (whether cells are active or inactive);
  • Bed / ground elevations; and
  • Bed material type or flow resistance value.

The TGC does not require any updates; however, it is recommended to review the TGC (e.g. 1D2D_Urban_001.tgc) before running the simulation to ensure all commands are correct.
