Here simulation refers to computer simulation of real-world phenomena or the operation of a real-world physical process or system. Mainly mechanical and mechatronic systems are considered here. Some multi physics problems are also presented.
To start a simulation, a model has to be developed to represent the main characteristics of the physical system. Model represents the system, whereas simulation represents the operation of the model (system).
Mainly CFD, FEM, and multi body mechanics are represented here.
