Name

Vector XYFunction — Compute an arbitrary vector function of x and y.

Output Categories

Parameters

fx
The x component of the function as a Python function of x and y Type: A string defining a function of x and y.
fy
The y component of the function as a Python function of x and y Type: A string defining a function of x and y.

Description

Compute a vector function of spatial coordinates x and y on a Mesh.

The function is evaluated by the Python interpreter, so it can contain any legal Python expressions. Any variables defined in the OOF2 Console window can be used in the function. For example, if you type

slope=3

in the Console, you can enter

slope*x + y

for fx or fy. The Python math library is also available. You could set fx to

sin(x*y/100)

for example.
