v := struct.node.pos.reference(sn)

Get the reference position of the structure node. The reference position corresponds to the nodal position at the time that the stiffness matrices of all finite elements that use the node were formed.


v - reference position vector or component


sn - pointer to a structure node

Component Access

f := struct.node.pos.reference (sn)->x

f := struct.node.pos.reference.x(sn)

Get the \(x\)-component of the reference position vector for the structure node.


f - \(x\)-component of the reference position vector


sn - structure node pointer

Access other vector components (\(y\), \(z\) in 3D; \(y\) in 2D) 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 (struct.node.pos.reference(sn,<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.

This is hidden. Added to include remaining vector component access functions for inline help.

f := struct.node.pos.reference.y(sn)
f := struct.node.pos.reference.z(sn)
