Summary0003016: bug in rigidBodyMotion solver
DescriptionCalulcated motions of the rigidBodyMotion solver are quite different since some recent commit. Linear and angular velocities are now numerically absolute identical, which is obviously wrong (see attached diff of log files, left side is with recent version)

Latest commit I have checked where rigidBodyMotion solver works correct is c1b380c from Thu Apr 26 15:36:16 2018 +0100
Steps To ReproduceCompare log-files from floatingObject tutorial with current version and e.g. commit c1b380c
TagsNo tags attached.

I believe this is now fixed in OpenFOAM-dev by commit 429c4188dbd015f6172b2d3a9c455d7d8fe9f3f1

Could you check and if it is satisfactory I will make the same change to OpenFOAM-6

I run different cases, and all look fine with the fix. Thanks!
