Detailed Description

template<class T, int D, int order>
class lsInternal::LocalLaxFriedrichs< T, D, order >

Lax Friedrichs integration scheme, which uses a first neighbour stencil to calculate the alpha values for all neighbours. The largest alpha value is then chosen for dissipation. Slower than lsLocalLocalLaxFriedrichs or lsEngquistOsher but more reliable for complex velocity fields.
