Hi,

It is created the negative volume in the following geometry. Why?

Please see volume 67.

-mAx- will become famous soon enough
go in examine mesh and select "volume" as Type.
Then Gambit will automatically set the lower and upper values in both slider.
You are right you have some negative volume cells.
Set now the upper value to 0 and press enter.
Gambit will show you where they are.

My advice: add more nodes an edge 592 especially in the middle
