Class
Foam::CloudStateFieldRef
Description
Wrapper for a reference to a dynamic Lagrangian field. It provides
convenient access consistent with that of the derived fields so that
expressions involving both kinds of field are readable. It also ensures
that old-time fields are maintained for a sub-mesh for the duration of the
inner correction iterations.
