Particle transport calculations in MIKE SHE PT are based on the groundwater flows from a MIKE SHE WM simulation. In principle, only groundwater fluxes are needed but to ensure that all the needed WM result data types are stored the user has to specify that results should be stored for an AD run in the WM input. Thus, you must check the appropriate checkbox under “Storing of Results” in the MIKE SHE WM GUI.
The user can choose between “SZ only” and “All hydraulic components”, however, for PT-simulations “SZ only” will be sufficient, since particle tracking is only calculated for the saturated zone.
The simulated particle distribution is stored with a desired frequency in the MIKE SHE WM GUI under “Storing of results” => “Grid series output”. It is important that the SZ and SZ-flow use the same storing frequency in order to run the following PT simulation. The WM result files to be used in the PT-simulations will be located in a folder with the same name as the *.SHE file.
