The flow equations are usually highly nonlinear. Additionally, discontinuous Galerkin formulations are used to conserve momentum, mass, and energy over internal and external boundaries. Shock-capturing techniques further reduce spurious oscillations. The test function is designed to stabilize the hyperbolic terms and the pressure term in the transport equations. The fluid flow physics interfaces use a Galerkin least-squares method to discretize the flow equations and generate the numerical model in space (2D, 2D axisymmetry, and 3D). A boundary layer mesh is automatically generated in order to resolve the gradients in velocity that usually arise at the surfaces where wall conditions are applied. The physics-controlled mesh functionality in the CFD Module accounts for boundary conditions in fluid flow problems in order to compute accurate solutions. In combination with the Chemical Reaction Engineering Module, you can also access generic descriptions for physical properties of gases (such as viscosity, density, diffusivities, and thermal conductivity). The CFD Module includes a Material Library with the most common gases and liquids. You can automatically or manually remove details included in a CAD representation that are not relevant for fluid flow. Generate flow domains, such as a bounding box, around imported CAD geometries. Additional multiphysics possibilities, such as fluid-structure interaction, are available when combined with other modules within the COMSOL ® product suite.

With the CFD Module, you can model conjugate heat transfer and reacting flows in the same software environment you use to analyze fluid flow problems - simultaneously. The ability to implement multiphysics in a model is important for fluid flow analyses. In addition to the list above, the CFD Module includes tailored functionality for solving problems that include non-Newtonian fluids, rotating machinery, and high Mach number flow. These capabilities are implemented through structured fluid flow interfaces in order to define, solve, and analyze time-dependent (transient) and steady-state flow problems in 2D, 2D axisymmetry, and 3D.
