Models Bodies of Complex Shape
- Can Handle General Loading/Boundary Conditions
- Models Bodies Composed of Composite and Multiphase Materials
- Model is Easily Refined for Improved Accuracy by Varying
Element Size and Type
Finite element analysis is needed in many fields of engineering (e.g. aerospace engineering, thermodynamic engineering, mechanical engineering) and science (e.g. meteorology, hydrology) to determine the behaviour of dynamic physical systems acting within a space composed of complicated shapes of a variety of different materials with widely varying properties. By dividing such systems into many smaller "finite elements" each of a simple homogenous nature, finite element analysis can provide a solvable set of mathematical equations that can provide a usable approximation with acceptable accuracy of the behaviour of the complete and very complicated inhomogeneous physical system.
please help
hat's a very broad question, but usually the advantages of finite element analysis is they can get you toward a solution when you have a very complicated shape undergoing very complicated loads (temperature, vibration, earthquakes, yielding, spread of plasticity), or you are trying to look at a part in great detail (more common in mechanical engineering).The disadvantage is the models are time-consuming to create, and verify, can be sensitive to boundary conditions (stress concentrations, local stresses) and sometimes the model needs to be refined repeatedly to give assurance that the results are reasonably accurate/valid.

prove that every subset of a finite set is a finite set?
Yes, you can use array-elements as parameters. Do you have any problem with that?
