Simulation Software for All Fluid Flow Applications

The CFD Module is the platform for simulating devices and systems that involve sophisticated fluid flow models. As is the case with all modules in the COMSOL Product Suite, the CFD Module provides ready-made physics interfaces that are configured to receive model inputs via the graphical user interface (GUI), and to use these inputs to formulate model equations. The particular physics interfaces that the CFD Module is equipped with enable you to model most aspects of fluid flow, including descriptions of compressible, nonisothermal, non-Newtonian, two-phase, and porous media flows – all in the laminar and turbulent flow regimes. The CFD Module can be used as a standard tool for simulating computational fluid dynamics (CFD), or in collaboration with the other modules in the COMSOL Product Suite for multiphysics simulations where fluid flow is important.

The CFD Module GUI grants you full access to all steps in the modeling process. This includes the following steps:

  • Selecting the appropriate description of the flow, for example single-phase or two-phase, laminar or turbulent flows, etc.
  • Creating or importing the model geometry
  • Defining the fluid properties
  • Adding source and sink terms, or editing the underlying equations of the fluid model, if required
  • Selecting mesh elements and controlling the density of the mesh at different positions
  • Selecting solvers and tuning them, if required
