EXTRAPOLATE - Extrapolation at freestream, arbitrary inflow boundaries
|
EXTRAPOLATE [BOUNDARY] [ORDER] {ZERO|0|ONE|1|FIRST} [zone_selector]
|
This keyword sets the extrapolation order used for boundary conditions
at freestream and
arbitrary inflow boundaries.
The default is zeroth-order extrapolation which should be more stable.
However, for grids with good mesh resolution near the boundary,
first-order is recommended, and should be more accurate.
