Maneuvering Simulation with 6-DOF Body
 
Hello everyone,

I got a serious question about maneuvering simulation in star-ccm+:

so far i try to simulate a 10/10 Z-Maneuver for a model scale container vessel. The vessel should be able to move in x and y-direction, but also rotate about the z-axis. The question for now is: do I need overset grid to simulate the translation and rotation, or is there any othe possibility to save some cells?

Regards
Tim

Tim,

You can accomplish this without any sort of dynamic mesh method (e.g., overset grids) unless you want a moving rudder and/or propeller. In fact, I used STAR-CCM+ to do maneuvering analysis of AUVs during my PhD research (http://vtechworks.lib.vt.edu/handle/10919/23777).

Hello Ryan,

first, congratulation for your PhD Thesis.

As you have already accepted, I want to simulate a moving rudder and a rotating propeller for maneuvering test. Therefore an overset grid is the best way to accomplish the rotating parts, in my opinion.
For now I am in the very first beginning of the porject and want to check all the possibilitys (thanks for the link). Maybe there are some further wuestions after reading your thesis ;)

Regards
Tim
