TUFLOW CATCH Tutorial M01: Difference between revisions

<li>In the 'Pollutant Export Properties' section, add the material block '<tt>ALL</tt>' (<tt><font color="blue">Material </font><font color="red">==</font> ALL</tt>) from the page linked below. This code block defines the default (or spatially uniform) pollutant export properties for each pollutant. Once uniform conditions are set, progressive specifications of material by material pollutant behaviour can be set. These specifications override previous settings on a spatial basis. Including the default (<tt>ALL</tt>) material block is considered best practice, as it ensures that all pollutants have export properties defined across the entire TUFLOW HPC domain, otherwise an error will occur. For more information on the pollutant export parameters, refer to <u>[https://docs.tuflow.com/catch/manual/2025.0/SimulationConstruction-1.html#SCTCCPollExpPE-4 Section 4.5.3.3 of the TUFLOW CATCH Manual]</u>.
