OVERVIEW OF COMPLEX APPLICATION:
 3D, 20 equidistant layers
 Including K-eps turbulence
 Temperature (ocean heat flux model)
 Salinity (including lock complex exchange IJmuiden)
 Cooling and process water included (also WWTP’s)
 About 100 feeding points included
 A weakly dynamic system

COMPARISON BETWEEN D3D & D3D FM:
 Simulation times
D3D: 4 days on 6 cores
D3D FM: 5 days on 1 core
 Computational effort
Grid creation and new possibilities
Location defined properties vs. grid defined properties
