Class
Foam::fv::localEulerDdtScheme
Description
Local time-step first-order Euler implicit/explicit ddt.
The reciprocal of the local time-step field is looked-up from the
database with the name provided.
This scheme should only be used for steady-state computations
using transient codes where local time-stepping is preferably to
under-relaxation for transport consistency reasons.
See also CoEulerDdtScheme.
