Geometric objects formed of the same material can be merged together to form a single domain
object.
This can be useful for creating complex geometries by combining various basic objects.
To form a single domain from the combined objects, it is important to uncheck the preserve
surfaces option for all the objects that are planned to be combined together.
For example, here I can use this feature to combine a sphere and a rectangle to form a
single domain object.
