Nodes are points where basic unknowns are determined in finite element analysis and where elements connect. There are two main types of nodes: external nodes located at element edges or surfaces and shared by multiple elements, and internal nodes located inside a single element. External nodes are further divided into primary nodes at corners or ends, and secondary nodes along edges but not at corners. Internal nodes are specific to each individual element.

- 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.
