Functions
-
const Field2D averageY(const Field2D &f)
Average over Y
Issues
Important: Only works if there are no branch cuts
Assumes every processor has the same domain shape
-
const Field3D averageY(const Field3D &f)
Average in Y
Issues
Important: Only works if there are no branch cuts
Creates static arrays
Not thread safe
Assumes every processor has the same domain shape
-
const Field2D averageX(const Field2D &f)
Average over X.
Issues
Assumes every processor has the same domain shape
Will only work if X communicator is constant in Y so no processor/branch cuts in X
-
const Field3D averageX(const Field3D &f)
Issues
Creates static arrays
Not thread safe
Assumes every processor has the same domain shape
Will only work if X communicator is constant in Y so no processor/branch cuts in X
-
BoutReal Average_XY(const Field2D &var)
Volume integral of Field2D variable Developed by T. Rhee and S. S. Kim
Issues
Assumes every processor has the same domain shape
Will only work if X communicator is constant in Y so no processor/branch cuts in X
-
const Field3D nl_filter_x(const Field3D &f, BoutReal w = 1.0)
Nonlinear filtering to remove grid-scale noise in X.
