TUFLOW XMDF Specification

This page describes the XMDF file structure written by TUFLOW. The XMDF format is an open format originally developed by Aquaveo and the general XMDF specifications are not described here.

Important Notes

• XMDF uses a directory like structure which TUFLOW utilises when writing outputs.
• XMDF supports Scalar and Vector type outputs.
  • Scalar outputs contain a single value per node (depth, water level, etc)
  • Vector outputs contain 2 values per node, an X and Y component (velocity, unit flow, etc)
