You do not need to include anything beyond OpenLB as this is standard library functionality (SuperLattice is derived from Serializable and implements the necessary methods for it to provide save/load).
I just checked and SuperGeometry actually doesn’t implement Serializable yet so if you need this you’ll need to add it on your own (not difficult). However, it is likely that you do not need to serialize the geometry, this commonly doesn’t take long to construct.
