Re: [Question #701782]: O.cell.volume=0 during flipCell
Question #701782 on Yade changed:

Status: Open => Answered
Bruno Chareyre proposed the following answer:
In principle all cells can be flipped, yes. What you get suggests that the automatic determination of the flip matrix fails.
Not sure why right now. You could pass one flip matrix explicitly.
Is cell.velGrad always symmetric or arbitrary (do you have rotation)?
Thanks for posting example numbers, it might help investigating.
