Hi all! My simulation domain is a unit box minus a complex geometry. When I run the simulation, I got lots of warnings during the gerris run, like "Gfs-WARNING **:inconsistent surface fractions 3 0.849391 0.812500 0.036891" .Can anyone give me a clue what may cause the "inconsistent surface fractions" waring? Or can I ignore the warning?I would appreciate it if you could help me.Yunda FEI
