The log file from the run is attached. I am happy to upload the entire case directory to dropbox if needed. I am running OF211 on CAELinux2013, with IHFoam's boundary conditions to simulate the waves.
I am trying to run IHDyMFoam on a torus floating in water, to calculate forces etc on it. To mesh I start with a blockmesh, continue with SnappyHexMesh without snapping. CheckMesh shows no errors. I've meshed it kind of roughly now at first and avoided snapping to check that the solver actually starts running
EDIT: twoDpointCorrector warning was not the cause of it. I had an unnamed patch after blockMeshing that caused the warning. New logfile attached.
The bottom of the log file looks as follows:
Code:
Execution time for mesh.update() = 2.78 s
time step continuity errors : sum local = 2.53764e-12, global = 3.64492e-15, cumulative = -1.75805e-08
GAMGPCG: Solving for pcorr, Initial residual = 1, Final residual = 3.71751e-08, No Iterations 10

I have previously ran quite a few tutorials and some self-constructed tests based on them, but this is my first time using dynamic meshing and IHFoam. I've tried refining without success, as well as changing resolveFeatureAngle and other factors in SNHM. Any hints or help is greatly appreciated!

Reason: Removed the cause of the warning. This was however not the reason for the error..
