Single vessel + non-cohesive sediment¶

In this example, you will add sediment morphology to a single vessel ship wakes example. The primary “input.txt” and vessel_00001 files are located in /simple_cases/single_vessel_morphology/.

Model setup

Setup “input.txt”

This example is slightly different from the previous example described in Single vessel + sediment (small domain for training session). Update the following sections:

Set a descriptive title for your simulation:

!-----TITLE-----
 TITLE = vessel_sediment_morph
If running in parallel, set the number of processors in X and Y:
!-----PARALLEL INFO-----
 PX = 4
 PY = 1
Set the bathymetry to the provided depth file:
!-----DEPTH-----
 DEPTH_TYPE = DATA
 DEPTH_FILE = ./depth.txt
If a “depth.txt” is not located in the working directory, you will need to run the “mk_depth.f” Fortran script to generate a depth file, which uses the “bathy_param.txt” file as an input. You can do this by typing the following into your terminal: gfortran mk_depth.f. Refer to Grid and Computational Time for parameter definitions.

Send the results to a folder named “output”:
!-----PRINT-----
 RESULT_FOLDER = output/
Set the dimension of the domain to 2400 x 60 (x and y directions, respectively):
!-----DIMENSION-----
 Mglob = 2400
 Nglob = 60
Set the computational time, plot time, station printing interval, and screen interval to 2000.0 s, 5.0 s, 50,000.0 s, and 5.0 s, respectively:
!-----TIME-----
 TOTAL_TIME = 2000.0
 PLOT_INTV = 5.0
 PLOT_INTV_STATION = 50000.0
 SCREEN_INTV = 5.0
Keep the single vessel characteristics and sediment morphology parameters as Single vessel + sediment (small domain for training session).

Postprocessing

For postprocessing examples, MATLAB and Python scripts are located in /simple_cases/single_vessel_morphology/postprocessing/. An example model result is shown below:
