A wide range of objective functions (variables within the system) are available for minimization or maximization: Mass, volume, temperature Strain energy, stress strain Force, displacement, velocity, acceleration Synthetic (User defined)
A structure is divided into small elements

There are multiple loading conditions which may be applied to a system. Point, pressure (Figure 3), thermal, gravity, and centrifugal static loads Thermal loads from solution of heat transfer analysis Enforced displacements Heat flux and convection Point, pressure and gravity dynamic loads
Elements can be 2 or 3 D 2D mesh for the image shown (mesh is denser

Unformatted text preview: around the object of interest) Magnetostatic Flux density Solutions may be color coded. 2D FEM solution for a magnetostatic configuration (lines denote the direction of calculated flux density and colour - its magnitude) Each FEA program may come with an element library, or one is constructed over time. • Rod elements • Beam elements • Plate/Shell/Composite elements • Shear panel • Solid elements • Spring elements • Mass elements • Rigid elements • Viscous damping elements Many FEA programs also are equipped with the capability to use multiple materials within the structure such as: • Isotropic, identical throughout • Orthotropic, identical at 90 degrees • General anisotropic, different throughout...
