Multirun scripts

  • Auto-generate multiple Delft3D-FLOW files for multiple subsequent (restarting) simulations

    • Master Defenition File (.mdf)

      • Adds Restid='identifier'+ run_nr, get's the identifier from the .mdf filename
      • Change smoothing time to zero Tlfsmo = 0.0000000e+000
      • Change times of restart and history files:

      Flmap = T_start output_time_step(remains the same) T_end

      Flhis = T_start output_time_step(remains the same) T_end

      • Due to a bug in Delft3D-FLOW, NetCDF cannot restart a map file from a specific time. Therefore, the index of the output step must be used. This is restart time step is calculated automatically and added with Restid_timeindex keyword and value. This is the only way to restart from a netCDF map file!

    • Morphology .mor file

      • Resets morphological smoothing time MorStt = 0

    • .bcc, .bct, .sed files

      • Adds duration of one simulation to all time steps
