Integration along Y (INTGY)

Use the Horizontal Integration - Y option to integrate the field along the Y direction.

Horizontal Integration - Y dialog options

This filter has no user-defined parameters.

Application Notes

This filter integrates the input transform along the Y component. It performs the inverse operation of taking the derivative with respect to Y. The zero wavenumber is set to 0.

Integration Operator

L(v) = iv^-1

Wavenumber Domain Variable Definitions

The following variables are used in the wavenumber domain:
k	Wavenumber increment, used to depict a radially symmetrical variable.	Where: np: number of points cs: cell size
μ	X-component of the wavenumber.
v	Y-component of the wavenumber.
r	Radial component of the wavenumber.
θ	Angular (polar) component of the wavenumber.
