StencilOrderReductionNearBND_forEULERIMPL
(experimental) switch for order reduction of x,y,z-derivative stencils in EULERIMPL setting
Default: StencilOrderReductionNearBND_forEULERIMPL = 'YES'
If EULERIMPL is used, then due to stabilization issues by default the order of the x,y,z-derivative stencils (see ord_gradient)
near the boundary (in an environment of h) is reduced by one. In some cases it can be helpful in terms of accuracy to switch it
off by StencilOrderReductionNearBND_forEULERIMPL = 'NON'. For example in cases with long thin geometries (see
SpecialBNDtreatmentEULERIMPL) it can greatly improve the results, if it is still stable.
