Hi, you beautiful foamers!

I'm pretty new to OpenFoam, but I've created a scenario where a ship is about to enter a lock. I made geometry files by using Blender, snappied them using the SnappyHexMesh Gui Addon on Blender and exported geometries to STL.

My simulation is set up as:
* Environment: Openfoam v2012.
* Multiphase simulation air, water.
* Move a ship by using solidBodyMotionFunctions::linearMotion at a low forward speed.
* The ship is moved through the lock for 200 meters.
* Depth profile in lock is varying.
* Solver: Interfoam.
* When I set a correct value for Location in Mesh the water and air looks as it should in paraView.

I can log the forces, even though they look quite awkward.
They don't make any sense.

I can find the location of the moving hull by doing a speed*time.
But how can I actually log it through OpenFoam?

Thank you for helping me out.

Have a nice day,

Ann Beate
