Even though FEM procedure may vary depending upon problem and approach used for solution, general steps in the FEM analysis remain more or less the same. The first step to the solution of the considered problem is to define the problem in detail with the available data. Based on the problem statement and available data, a mathematical model is developed defining the geometry of the problem, material properties, assumptions and simplifications used, governing equations, boundary and initial conditions.
In this section, the general steps used in the solution using the finite element method are described with explanations.
Step 1: Discretize and select element types
This step involves subdividing body into an equivalent ...
