what's difference between node & element & block in analysis software like Ansys?
engr.uvic.ca said:FEA Theory: Model [a] body by dividing it into an equivalent system of many smaller bodies or units (finite elements) interconnected at points common to two or more elements (nodes or nodal points) and/or boundary lines and/or surfaces.
engr.uvic.ca said:A node is a specific point in the finite element at which the value of the field variable is to be explicitly calculated.
A node is a point or a location in a physical or mathematical system where the properties of the system can be measured or evaluated. In the context of computer science and engineering, a node can refer to a point in a network or graph, or a point in a finite element analysis model.
In the context of finite element analysis, an element is a basic building block used to model a complex physical system. It is a small, geometrically simple shape or volume that represents a portion of the system. Elements are connected at their nodes to form a mesh that approximates the behavior of the entire system.
In the context of finite element analysis, a block is a type of element that is typically used to represent a three-dimensional physical system. It is a three-dimensional shape or volume that is divided into smaller elements to create a mesh. Blocks are often used to model solid structures, such as buildings or bridges.

An element is a basic building block used to model a system, while a block is a type of element that is typically used to represent a three-dimensional system. Blocks are divided into smaller elements to create a mesh, while elements are not necessarily divided further. Blocks are often used to model solid structures, while elements can be used to model various types of systems.
