Basic steps in
Finite element method
1.Create and discretize the solution domain into finite elements.
2.Assume a shape function to represent the physical behavior of an element.
3.Develop equations for an element.
4.Construct the global stiffness matrix.
5.Apply boundary conditions, initial conditions, and loading.
6.Solve algebraic equations to obtain
nodal results, such as displacements values at different
nodes etc.
7. Obtain other important information.
