hi,sean,"unit" is that two or more faces (volumes) unit into one REAL face (volume). "merge" is that two or more faces (volumes) merge into one VIRTUAL face (volume).

Real merge option is available in case of volumes. Real merge requires volumes to be connected (i.e. must have a shared face) where as real unite will work for two or more intersecting (connected/disconnected) volumes. Also, topology of the resulting volume would be different in each case.

For the difference in topology of Merge and Unite commands, how does it affect the following meshing?

This has been confusing me awhile, too

Merge deletes the shared connected face but leaves all other faces of the original volumes unchanged.

Unite may also unite other faces in addition to deleting the shared face (if any).

For grid, are the above mentioned the only difference between "merge" and "unit"?
