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.

Detail Geometry Creation

Solid geometry of an assembly

Geometry representing the air around an
electric motor armature is created for a
later field analysis.

Patch surfaces created on larger areas
for applying boundary conditions.
