Flux reconstruction methods¶
Group /input/model/unit_XXX/discretization/reconstruction = WENO¶
BOUNDARY_MODEL
Boundary model type: 0. Lower WENO order (stable) 1. Zero weights (unstable for small \(D_{\mathrm{ax}}\)) 2. Zero weights for \(p \neq 0\) (less stable)
Type: int
Range: \(\{0, 1, 2\}\)
Length: 1
WENO_EPS
WENO \(\varepsilon\)
Type: double
Range: \(\mathbb{R}^{>0}\)
Length: 1
WENO_ORDER
WENO order, also called WENO \(k\):
Standard upwind scheme (order 1)
WENO 2 (order 3)
WENO 3 (order 5)
Type: int
Range: \(\{1, 2, 3\}\)
Length: 1
Group /input/model/unit_XXX/discretization/reconstruction = KOREN¶
The Koren scheme implemented in CADET intrinsically uses a van Leer flux limiter. It can reach a maximum order of 2 depending on the smoothness of the solution. The BOUNDARY_MODEL is intrinsically set to 0 (stable).
KOREN_EPS
Set \(\varepsilon\) in the van Leer flux limiter
Type: double
Range: :math:`qe 0`
Length: 1
