## Chapter 1: Basic Capabilities Modeling

This chapter describes the basic physical models and some other basic capabilities found in ANSYS CFX:

- Domains
- Physical Models
- Sources
- Material Properties
- Mixture Properties (Fixed, Variable, Reacting)
- Efficiency Calculation
- Wall Condensation Model

Additional information on using boundary and initial conditions is available:

- Boundary Condition Modeling

- Initial Condition Modeling.

Descriptions of more advanced physical models and how the basic models extend to more complex cases are provided in:

- Turbulence and Near-Wall Modeling

- Domain Interface Modeling

- Transient Blade Row Modeling

- Multiphase Flow Modeling

- Particle Transport Modeling

- Combustion Modeling

- Radiation Modeling

- Rigid Body Modeling

- Real Fluid Properties

- Coupling CFX to an External Solver: ANSYS Multi-field Simulations

- Aerodynamic Noise Analysis

- Wall Condensation Model

Additional information is available:

- For general solver and convergence advice, see Advice on Flow Modeling.

- For information on parallel processing and its implementation, see Using the Solver in Parallel.

- For information on expert parameters, see Expert Control Parameters.

- For information on extending the capabilities of CFX through Fortran subroutines, see User Fortran.

- For a description of the mathematics used in the implementation of these models, see Basic Solver Capability Theory in the CFX-Solver Theory Guide.
