Nonlinearity is natural in physical problems. In fact the linear assumptions we make are only valid in special circumstances.
However, linear analysis is not adequate and nonlinear analysis is necessary when designing high performance components, establishing the causes of failure, Simulating true material behavior.
Dynamic analysis is a type of structural analysis which covers the behavior of structures subjected to dynamic (actions having high acceleration) loading. Dynamic loads include people, wind, waves, traffic, earthquakes, and blasts. Any structure can be subjected to dynamic loading. Dynamic analysis can be used to find dynamic displacements, time history, and modal analysis.
Static structural analysis is mainly concerned with finding out the behavior of a physical structure when subjected to force. This action can be in the form of load due to the weight of things, Other kind of excitation such as an earthquake.
If a load is applied sufficiently slowly, the inertia forces can be ignored and the analysis can be simplified as static analysis.

Combustion is a chemical process in which a substance reacts rapidly with oxygen and gives off heat.
Turbulent fames exist in very simple devices such as a blow torch, in domestic boilers, car engines, industrial burners for process heating, and in aircraft for stationary gas turbines. The range of power in these example ranges from a fraction of kW to hundreds of MW.
In fluid mechanics, multiphase flow is simultaneous flow of: – Materials with different states or phases.
Virtually every processing technology must deal
with multiphase flow, from cavitating pumps and turbines to electrophotographic processes to papermaking to the pellet form of almost all raw
plastics.
Computational fluid dynamics, usually abbreviated as CFD, is a branch of fluid mechanics that uses numerical analysis and algorithms to solve and analyze problems that involve fluid flows.
Ongoing research yields software that improves the accuracy and speed of complex simulation scenarios such as transonic or turbulent flows.
