### 2.2.2. CFX-Solver

CFX-Solver solves all the solution variables for the simulation for the problem specification generated in CFX-Pre.

One of the most important features of ANSYS CFX is its use of a coupled solver, in which all the hydrodynamic equations are solved as a single system. The coupled solver is faster than the traditional segregated solver and fewer iterations are required to obtain a converged flow solution.

Additional information on the CFX-Solver models is available; for details, see Basic Capabilities Modeling in the CFX-Solver Modeling Guide.
