Mean free path calculation in 'Volumes' element of the 'Data' tree

[Picaut]

Is-it necessary to display a check box for 'Calculate the mean free path'. Can it be calculated automatically and display in the 'Mean free path' ceil? In addition, if not calculated or not defined, the value of the mean free path should not defined/display (i.e. display 'not defined')

I don't know what it is. It is never used anywhere else than this node.. Maybe a postponed feature ?

This property can be removed.

There is no remaining attribute in this node. We could add a description text in order to keep the property node.

[Picaut]

Yes. Good idea.
