Basic Steps in the Finite Element Method (FEM)

There are three basic phase of Finite Element Analysis (FEA), which are furtherly divide in substep.

Preprocessing Phase

  1. Create the geometry and discretize the geometry in to node and elements (Finite Element).
  2. Select an element type or shape function to represent the physical behavior of a generated element.
  3. Generate the equation for each element.
  4. Assemble all the equation to represent the entire problem. Then generate global stiffness matrix.
  5. Apply Boundary Condition (Load, Support or Initial Condition).

Solution Phase

  1. Now solve the assembled equation to obtain result.

Post processing Phase


  1. Find out the result and other important information

Need of knowledge of FEM for Analysis Software like ANSYS


     The finite element Method (FEM) is a numerical analysis procedure, which is used to solve a large number of engineering problems including stress analysis, heat transfer, mass transfer electromagnetism and fluid flow.
     For effective use of ANSYS Software or other Finite Element Analysis software package, you should have good knowledge of the basic working of FEM. Good knowledge of basic working of FEM and basic engineering subject (like SOM, fluid mechanics etc. ) will lead you in use of FEA software.
     Engineering problems are mathematical models of physical situation or real situation deal in our daily life. Mathematical models are differential equation with a set of corresponding boundary condition and initial conditions. The differential equations are created with the help of basic engineering law and some nature's principles. The governing equations balance the load, mass or energy.
     We can not obtain exact solutions of large number of practical or real world engineering problems. This is due to complex nature of governing differential equations or difficulties which arise from dealing with the boundary and initial conditions.
     While analytical solution provide the exact result of a problem within the system, on other hand numerical solutions approximate exact result only at discrete point, called nodes.
     ANSYS is a very powerful and impressive engineering analysis tool which is used to solve the large number of problems. But a user without a basic understanding of the Finite Element Method is same as a technician with good and impressive tool but do not know inner working of object to be repair.
