Figure 4.34 Generation of internal wave boundary data using the MIKE 21 Toolbox
'Random Wave Generation' and 'Regular Wave Generation' tool
The length of the simulation is 8 minutes and 20 seconds (corresponding to
5001 time steps) for the regular wave simulation and 10 minutes for the direc-
tional wave simulation.
The computation time depends on the speed of your PC. For a laptop IBM
T40 Pentium M (Centrino, 1.6 GHz and 1GB DDR RAM) the required system
time is approximately 2 hours (the system CPS is approximately 190,000
points/second) for the regular wave simulation and approximately 5 hours
(the system CPS is approximately 180,000 points/second) for the directional
wave simulation.
You may reduce the length of the simulations in order to reduce the overall
CPU time.
Model results
Figure 4.35 shows 2D visualisation of the simulated instantaneous surface
elevation for the two wave situations. The most visible wave phenomena are
refraction, shoaling, nonlinear wave-wave interaction (generation of higher
harmonic waves), wave breaking and run-up.
