在rhoPimpleFoam/LES/pitzDaily 算例里找到了这个应用,
---Properties Second order Unbounded Attempts to limit the unboundedness of the linear scheme ---Usage The scheme is specified using: divSchemes { default none; div(phi,U) Gauss filteredLinear2 <k> <l>; } ---Where the coefficients --k: Scales the rate at which the correction is applied 0 : linear 1 : fully limited --l: Maximum allowed overshoot/undershoot relative to the difference across the face. 0 : no overshoot/undershoot 1 : overshoot/undershoot equal to the difference across the face对于矢量时候 用filteredLinear2V, 求解出来流场的unboundedness 介于 Gauss Linear (unbounded) 和 Gauss GammaV (bounded)中间
