This chapter explains how to use the Laminar Flow interface, found under the Fluid Flow>Single-Phase Flow branch () when adding a physics interface. This physics interface is used to model and simulate fluid mechanics for laminar, incompressible fluids. The engineering community often uses the term CFD, computational fluid dynamics, to refer to the numerical simulation of fluids.

See The Nonisothermal Flow and Conjugate Heat Transfer Interfaces for details about the modeling of laminar nonisothermal flows.

The optional CFD Module includes support for turbulent flow, turbulent nonisothermal flow, multiphase flow, and many other fluid-flow related features.
