"apply" is not a scheme, but if you not select "apply" I assume Gambit will not mesh your volume.
"Default" is the default mesh scheme automatically choosed from Gambit. (for exampls if you try to mesh a cylinder, Gambit will automatically choose Hex-Cooper as default scheme. But you are free to mesh it mit tetra)

but when i choose scheme default gambit make a mesh and export it to fluent well and i choose the interval size and hex map so why gambit describe this kind of scheme mesh as defaul ?

thank u max can u add me to your massenger

I assume your volume doesn't seem to be hex-meshable
