Answer:
Discretization is the process in which elements are divided into the equivalent finite number. In discretization, variation occurs in different properties of the elements like force and materiel are applying in the input.
Each element in the discretization are associate with real physical response of the body. And it result in drastic change within the body then, discretization process is done.
Role of discretization in finite element analysis are:
The process of diving the elements in the equivalent number which are associated with the nodes. Then, the discretization in finite element method of an element are finite element analysis.
And the discretization process are basically depend upon the variation in the result. The smallest element produce the meaningful result in discretization.
