(u, v, w, Cx=1e-05, Cy=1e-05, Cz=1e-05)[source]¶ Calculates the smoothness cost function by taking the Laplacian of the wind field.
All arrays in the given lists must have the same dimensions and represent the same spatial coordinates.
- Parameters
- u: Float array
Float array with u component of wind field
- v: Float array
Float array with v component of wind field
- w: Float array
Float array with w component of wind field
- Cx: float
Constant controlling smoothness in x-direction
- Cy: float
Constant controlling smoothness in y-direction
- Cz: float
Constant controlling smoothness in z-direction
- Returns
- Js: float
value of smoothness cost function
