seakeeping

Did you have a look at the Seakeeping best practices? You can find these in the Fine Marine documentation and they include the postprocessing. 

If this does not give you what you're looking for, please don't hesitate to provide more information on what you're looking for with this simulation.

hello ,

Yes we saw the best practices but unable to get the correct idea of how to animate the result ,

so can you tell us the process of doing the post processing of seakeeping.

thank you

Hello,
animations should be done by saving intermediate solutions through the simulation time.
These intermediate saving should be done with "Probes". Probes can be volume or surface data. we clearly advise to only use surface data since they are enough to visualize the majority of the simulation and reconstruct an animation. But overall, they are much lighter than volume data.
Surface probes can be activated through the Output menu > Probes > Surface data.

For a seakeeping animation, I would advise to use "wall probes" and "free surface". See "User Guide > Output > Output > Probe Variables > Surface Probes" for all information about surface probes in the user manual.

For the beauty of the animation, the human eye likes to see a frame rate a minimum of 24 pictures per second. Hence, I would recommend to use a frequency of probe saving of 1/24 = 0.042s at least. If you decrease that value to 1/48, the animation will be even better, and so on.

At the end of the simulation, you should reconstruct the probes and import them into CFView. See "User Guide > Post-Processing > Open unsteady results". While in CFView, you should save a picture for every probe step. Then, you can either use the "animated gid" reconstructed by CFView (not really high quality and low disk size), or use free software like "mencoder" to reconstruct the animation with all the PNG files saved by CFView at the frame rate you like.

Hope this helps.
