What is Node and
Types of Nodes in FEM
2. What is Node?
Nodes are selected points at which basic unknowns are to be
determined in the finite element analysis. Nodes are those points
where elements are connected.
There are two types of nodes
a) External nodes
-Primary external nodes
-Secondary external nodes
b) Internal nodes
3. Types of Nodes
External Nodes
Nodes which are occur at edges or surfaces of
element are called as external nodes. They
are common to two or more elements.
Primary external nodes: Nodes which are
occur at corners or ends of element are called
as primary external nodes
Secondary external nodes: Nodes which are
occur along the edges of element excluding
corner nodes are called as secondary external
nodes
Internal Nodes:
Internal nodes are the one which occur inside
an element. They are specific to the element
selected and not common to other element.
