Hello everybody,
I am currently working on an model comparison between MoorDyn V2 and OrcaFlex.
I ran a model of a line with 2 fixed end points in a regular wave and the results there are almost the same.
Now I use the same wave input or a buoy with a center of mass that is lowered. (input files below)(wave amplitude 4m, period 8.33s)
buoy_mass.txtwater_grid.txtwave_frequencies.txt
But here something strange happens. The buoy is moving backwards. The usefful results are shown below.
The buoy does not lay flat and for a basic calculation no cd or ca coefficients are included.
When only a current acts on the buoy the models show the same results.
Any ideas?
The buoy has a center of mass 2.67m above the bottom of the buoy. I think this is correctly implemented no?
