Hi pcwang,
As you mention, it is highly likely that there is something wrong with OpenFOAM in your workstation. I would recommend re-compiling OpenFOAM first and then olaFlow to see if you resolve...

Hi Stan,
- Perhaps you should consider the impact of the wave reflections on the structure to evaluate whether that wave height is reasonable.
