Detailed Description

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

Stabilised local time-step first-order Euler implicit/explicit ddt. The time-step is adjusted locally so that an advective equations remains diagonally dominant.

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.
