Simulation - definition

Simulation is the process of creating and analysing a mathematical, physical or logical model that replicates the behaviour of a real system, phenomenon or process under controlled conditions. The purpose of simulation is to understand the operation of a system, to predict its response to different stimuli and to support design, operational or experimental decision-making without interfering with the real object.

In engineering, simulation plays a key role in testing mechanical designs, electronic systems, control systems and industrial processes. It is also used in computer science to study algorithms, Computer Networks or software architecture. At a mathematical level, simulations are based on sets of differential, algebraic or statistical equations that describe state variables and their interrelationships in time and space.

Simulations can be deterministic or probabilistic, depending on whether they take random factors into account. They can be run in real time, accelerated or decelerated, depending on the objectives of the analysis. Technical applications use specialised software environments such as MATLAB/Simulink, ANSYS, SPICE or CAD to model complex systems taking into account non-linearities, delays and feedback.

Simulation allows the identification of design errors, the evaluation of operational parameters, the testing of failure scenarios and the optimisation of equipment and process performance. In fields such as energy, transport, medicine or aviation, it is an indispensable analytical and educational tool, reducing the risk of costly physical experiments or dangerous real-world tests.
