interface.node.normal
Syntax
- v := interface.node.normal(in)
Get the normal vector for the interface node, which is an area weighted average of the interface elements it is connected to.
Returns: v - normal vector
Arguments: in - interface element pointer
Component Access
f := interface.node.normal
(in)->x
- f := interface.node.normal.x(in)
Get the x-component of the normal vector for the interface node, which is an area weighted average of the interface elements it is connected to.
Returns: f - x-component of the normal vector Arguments: in - interface element pointer
Access other vector components (y, z) by substituting the component name where x appears above. See Member Access Operator for information about accessing members from data types using ->

Deprecated Component Access
Component access by adding an optional integer in the function arguments (interface.node.normal(in,<int>)
) is deprecated. It remains available but will not be supported in future versions. See Component Access with Integers in FISH on the Deprecated Commands and FISH page for details.
