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.
