13.4.1 Global Variables

This section lists Global/Shared Variables and Grid/ Mesh variables which can be used everywhere within the Expression Editor.

Global/Shared Variables

The following Shared Global variables are available in the Expression Editor:

Expression	Function	Example
pi	π
time	Time in seconds	minutes = time / 60
x,y,z	Position	new_x = x +2

Table 13.6 - Global/Shared Variables

Grid/Mesh Variables

The following Grid/Mesh variables are available in the Expression Editor:

Expression	Function
Grid Nodes
x,y,z	Original mesh coordinates [m] as scalars
coord	Original mesh coordinates [m] as a vector
Cells
volume	Cell volume [m3]
Faces
normal	Face normal [m] (a vector)
area	Face area [m2] (a scalar)
