Hi,

I have 3 connected real volumes in GAMBIT. I use the Geometry Cleanup tool to connect duplicated vertices, edges and surfaces. After I do that the 3 volumes become virtual volumes and I cannot convert them to real, GAMBIT says that there is some other virtual lower geometry, but there isn't any. Because the volumes are now virtual I cannot perform any volume splitting which I need to proceed with the meshing. How to clean up the geometry and keep it real?

Thanks

Use Gambit 2.4 (just released) or delete the newly cleaned volume and leave lower topology. Then rebuild volumes from lower real entities by stitching.
