Multiple vessels-induced morphology changes

In this example, you will add multiple vessels to the vessel-sediment morphology simulation. The primary “input.txt” and corresponding vessel files are located in /simple_cases/multi_vessel_morphology/.

Model setup

Setup in “input.txt”

Continue building from the previous two examples (Single vessel + sediment (small domain for training session) and Single vessel + non-cohesive sediment) by creating additional vessel files.

Add up to 6 vessels to the simulation:

!-----SHIP WAKES-----
 VESSEL_FOLDER = ./
 NumVessel = 6

You need 6 vessel files: vessel_00001, vessel_00002, ... in the current folder. In vessel_00001, specify:

Title: Vessel # 1
Pressure, 1
Length(m), Width(m), Alpha1(0.5),Alpha2(0.5), Beta(0.5), P(draft,m)
10.0  5.0, 0.5, 0.5,0.5, 1.5
Time, X(m), Y(m)  (relative to the orgin of the coordinates)
0.0   40.0   60.0
25523.0  180040.0  60.0

In vessel_00002, specify:

Title: Vessel # 2
Pressure, 1
Length(m), Width(m), Alpha1(0.5),Alpha2(0.5), Beta(0.5), P(draft,m)
10.0  5.0, 0.5, 0.5, 0.5, 1.5
Time, X(m), Y(m)  (relative to the orgin of the coordinates)
0.0   50.0   60.0
100.0   50.0   60.0 (release at 100.0 sec from x=50.0 m
25623.0  180040.0  60.0

vessel_00003 - vessel_00006 can be made in the same way.

Postprocessing

For postprocessing examples, MATLAB scripts located in /simple_cases/multi_vessel_morphology/.

From top to bottom: 1) sediment concentration induced by six vessels; 2) morphological change due to suspended load (not consider porosity); 3) morphological change due to bedload (not consider porosity); and morphological change due to total load.
