For some inspections, it is useful to split the tank in several parts in order to consider only the shell or only the bottom plate, for example.

Show only the initial mesh and go to Separate Shell. The computation is done automatically; it can take a few seconds. We now have a new folder Separate shell containing two polylines representing the top contour and the bottom contour of the tank, as well as the three separated parts of the tank (Shell, Bottom and Top).

The tank is separated in 3 meshes: the shell, the top and the bottom

The project is now fully ready to start the complete analysis of the tank.
