[Virtual-iCFD]

I encountered the following output message when executing interDyMFoam using version 1.7.0 and I am not sure whether I should continue or kill my run, since my linear and angular velocity becomes "nan" as shown below. If anyone can provide me some useful guideline. I greatly appreciated.

Thank you,
