Hi
after running the tutorial for the DTCHull I tried my first own hull to be calculated in 1:1 scale.
For that I took the parameters for the blockmesh and toposetdict from DCTHull and scaled in to the parameters from my yacht (L, B, D, H) and also scaled the blockmesh from 6 m Modell to a 100 m Yacht.
The result at a speed of 9.18 m/s shows a lot of small wavws generated at the toposetdict boundaries leading to funny waves alongside the hull (please see attached).
What can I do to avoid this? Do I have to change the sizes of the water mesh?

The same applies when I scale up the DCTHull from 6 m to bigger scale.

NO IDEAS?
May there be a problem with the stl model? How fine should the mesh be in relation to the mesh defined by toposetdeict an blockmeshdict?

Hi, I'm a final year student trying to run simulation of my own hull using DTC Hull code as a guide, however i couldn't really "merge" the hull on the domain. Tried to run the codes several times. I wonder if you could help me on that. Thanks a lot.
