Good Morning Everyone,


I am working on finding the heave, sway and roll response of 2-D floating body with wave in openfoam(V-5). I generate wave and it is perfect. simulations also ran without any error. Now i want to calculate the response of floating body with wave please suggest me how to do so in openfoam.


Regards,
Akshay

Position of your defined body is written down to solver log at each iteration. You should write a script that reads the position data in solver log and accumulate it with iteration or simulation time to plot a graph. You can use python or Linux-bash for script.

Dear Sir,


Thanks for your reply..! can you will explain what is the order of 6dof motions(surge, sway heave, roll, pitch, yaw) in orientation tensor.


6-DoF rigid body motion
Centre of rotation: (2 0.02 0.4)
Centre of mass: (2 0.02 0.4)
Orientation: (1 0 8.6106890225e-21 0 1 0 -8.6106890225e-21 0 1)
Linear velocity: (0 0 0)
Angular velocity: (0 1.44659575578e-17 0)

hello Roithamer,
I'm also running floating obect (2d case) using olaflow. I'm able run the simulation successfully but to plot surge, heave i don't have much knoweledge in that could you share more info on this .
thanks in advance
