Finite Element Method
In Civil Engineering
What is Discretization?
2. What is Discretization?
The process of dividing the structure into number of finite elements is called as
discretization of an element in finite element analysis
In the discretization- the number, shape, size and configuration of elements have
to be decided in such a manner that the real structure is simulated as closely as
possible.
The discretization is to be in such that the results converge to the true solution.
3. Domain/Structure: Rectangular Slab
1. Dividing the slab into ‘n’ number of
subdomains is called as discretization of the
domain.
2. Each domain is called as ‘Element’.
3. The collection of element is called as ‘Finite
Element Mesh’.
4. The elements are connected at points called
as ‘Nodes’.
5. When elements are of same dimension it is
called as uniform mesh otherwise non-
uniform mesh.
Question: What is discretization? Explain with suitable example
