Ben.Kim is on a distinguished road
I did simulation small fluid capillary simulation(<<10mm).


when I change some geometry, I met 'floating point error'.


but, some simulation is working in very similary geometry.


so, I think this is mesh problem. because I just chagne only geometry and I did not fix other option(including mesh).


however, I don't know essenctial mesh condition.


I always do mesh sizing using body sizing as element size.


can you help me with how do I checking mesh?
