**Preprocessing**

Define the geometric domain of the problem.

Define the element types to be used.

Define the material properties of the elements.

Define the geometric properties of the elements (length, area, and the like).

Define the element connectivities (mesh the model).

Define the physical constraints (boundary conditions). Define the loadings.

**Processor**

computes the unknown values of the primary field variable(s)

computed values are then used by back substitution to compute additional, derived variables, such as reaction forces, element stresses, and heat flow.

**Postprocessing**

- Postprocessor software contains sophisticated routines used for sorting, printing, and plotting selected results from a finite element solution.
