Please see HfFluidDemo.cpp for examples of how to use the height field fluid along with buoyant collision shapes.
The implementation is still lacking in my ways:
1) Need to complete more collision algorithms for buoyant collision shapes
2) Support compound buoyant shapes
3) The buoyancy model isn't that great
4) Fluid volume can be lost over time

Generally, however, it is best to avoid copying entire arrays, but use a
reference.
typedef btAlignedObjectArray<btSomeClass> Array;
Array a;
Array b = a;//avoid this whenever possible
This is much better:
Array& b = a;//use a reference
const Array& b = a; //or const reference
