Multiphysics simulation
In computational modelling, multiphysics simulation (often shortened to simply "multiphysics") is defined as the simultaneous simulation of different aspects of a physical system or systems.[1] For example, simultaneous simulation of the physical stress on an object and the temperature distribution of the object would be considered a multiphysics simulation.[2] Multiphysics simulation is related to multiscale simulation, which is the simultaneous simulation of a single process on either multiple time or distance scales.[3]
As an interdisciplinary field, multiphysics simulation can span many science and engineering disciplines. Simulation methods frequently include numerical analysis, partial differential equations and tensor analysis. [4]
Multiphysics simulation process
The implementation of a multiphysics simulation follows a typical series of steps:[1]
- Identify the aspects of the system to be simulated, including physical processes, starting conditions, and boundary conditions.
- Create a discrete mathematical model of the system.
- Numercally solve the model.
- Process the resulting data.
Mathematical models
Mathematical models used in multiphysics simulations are generally a set of coupled equations. The equations can be divided into three categories according to the nature and intended role: governing equation, auxiliary equations and boundary/initial conditions. A governing equation describes a major physical mechanisms or process. Multiphysics simulations are numerically implemented with discretization methods such as the finite element method, finite difference method, or finite volume method. [5]
