Hi all,
I was wondering if someone knew how to extract and log the orientation of a 6DoF object? I am interested in being able to record the pitch, roll, and yaw angles of a ship model (preferably in degrees, but radians is fine too). As far as I can discern the orientation is stored in a tensor Q which is used among other things in the 6 DoF motion solvers. I was wondering how you modify what is logged and what files must be modified (both runtime and or OF files) so that I can get a file similar to the "forces" file output of the force function group? Any help would would be greatly appreciated.

Hi Dave,
I know this is a very old post but your question is very interesting. did you find a way to do that?

Best regards

Hey Federica,

check out this thread:
How to plot pitch motion for free decay test?

Hope that helps

Hi mona!
Thanks for your reply! The post was really helpful. Now I'm interesting in doing it in run time, I mean I need to extract the orientation from the log file in run time to use it in my modified restraint library.

Any suggest?

Thanks in advance

Federica
