Lastly, users recommend Ansys Fluent for flow analysis of turbo machines, as they believe it is better than Fluent Solver. They find it helpful for post-processing and 3D simulations, making it suitable for CFD simulation.

In summary, some common recommendations from users include using Ansys Workbench instead of CFX for its additional utilities, studying the software thoroughly before implementation, and utilizing Ansys Fluent for flow analysis of turbo machines and CFD simulation.

ANSYS CFX is a powerful tool used by engineers, researchers, and students to solve complex fluid flow problems across many industries. The software has been lauded by users for its ability to simulate turbine components and perform multi-phase flow analysis through ducts and pipes. Engineers who have used ANSYS CFX have found the software useful for confirming and improving initial estimations made with Thermal Transient analysis when developing cooling systems. This saves time and money, making it an ideal solution for industrial applications.

Users of ANSYS CFX have also found the software helpful in solving aerospace fluid dynamics problems. The discretization of components into multiple bodies provides high resolution which helps in achieving accurate results. Additionally, cavitation modelling can be done to analyse CAD models and observe fluid behaviour over it. Overall, ANSYS CFX offers quick simulations at a lesser cost than traditional testing methods, enabling users to focus on real-world problems and design solutions more efficiently.

User-friendly interface: Reviewers have consistently praised ANSYS CFX's user-friendly and aesthetically pleasing interface. It has been found to be easy to navigate, with clear identification of required fields for setting up simulations efficiently.

Unique parameter profile utility: Many users appreciate the unique feature of ANSYS CFX that allows them to directly enter the profile of parameters like velocity, eliminating the need for a user-defined function. This sets it apart from other software in its category, such as ANSYS Fluent.

Powerful post-processing utility: The post-processing utility CFD-Post has been highly regarded by reviewers due to its numerous features that allow for detailed result analysis and computation of derived parameters using expressions, planes, etc.

Difficult to Use: Users have found ANSYS CFX to be difficult to use and time-consuming to learn. The user manual is not very helpful, and sometimes it is hard to figure out how to change certain settings as they are hidden or not well explained in the guide. Some users have also mentioned that the CAD software is challenging to use.

Meshing Issues: ANSYS CFX does not have its own meshing utility, and mesh needs to be imported from other utilities such as Fluent Meshing ICEM CFD. Additionally, the mesh program could be more automatic, which would save time. This issue has been reported by several reviewers.

Simulations Take a Long Time: Running simulations on ANSYS CFX can take a long time, which increases computational costs. This issue has been mentioned by multiple reviewers who find this aspect of the software frustrating.

Ansys CFX is a CFD software for turbomachinery applications. The solution helps to shorten development time with streamlined workflows, advanced physics modeling capabilities and accurate results.

I am developing a valve using Ansys CFX has been helpful to confirm and improve the accuracy of my initial estimations made with Thermal Transient analysis. The flow simulation is much more accurate than the film coefficient boundary condition in thermal transient. It is a very good utility if one is planning to run multiple runs by varying the input parameters on the same geometry.

The GUI of Ansys CFX is pleasing to the eye and at the same time user friendly, making it a lot easier to identify the required fields.
The numerical scheme is based on Finite Volume Methods. It supports multi-phase flows with no mass transfer.
In the Ansys CFX, adaptive networking can be used for GGI interfaces and single domains without restricted physics.

One thing which I think they can do is provide flexibility to the user to modify the stuff inside the black box
Sometimes the errors can be confusing. The geometry of design and meshing is sometimes troublemaking.

The useful thing is it shows result in different color code.
Cavitation Modeling- there are several mathematical models on that.
It has made redesigning mounting systems extremely easy.

The interface of Ansys CFX is much neater than Ansys Fluent. I found it much easier to define materials and boundaries in Ansys CFX. Also, this will allow me to get much more accurate results compared to a simples Thermal transient analysis
