Detailed Description

template<class Type>
class Foam::fv::CoEulerDdtScheme< Type >

Courant number limited first-order Euler implicit/explicit ddt.

The time-step is adjusted locally so that the local Courant number does not exceed the specified value.

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.
