Ansys CFX Reviews

It is the best robust solver that is more suitable for the turbomachinery applications.

It lacks some of the k-epsilon family turbulence models.

I have used it to simulate the performance characteristics of

Multi-phase modeling, User functions, and GUI. It is very easy and intuitive.

The numerical scheme is based on Finite Volume Methods. It supports multi-phase flows with no mass transfer.

ANSYS CFX does not support boiling and condensation under their multi-phase models.

Integrate boiling and condensation models

In the CFX, adaptive networking can be used for GGI interfaces and single domains without restricted physics.

It is a software that has a very high performance in turbo machines and has proven itself in this field.

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

The main issue, in my opinion, is the lack of deep information readily available for every user. Sometimes you need to email them and this will take time to solve the issues.

Study before implementing. Boundary conditions, topology share, and other things are not always straight forward.

I am developing a cooling system for a mechanical gripper. 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.

Post Processing is very helpful. Downsides so many steps of process for loading the software.

Not specifically, Downsides is the process of running simulations

For Post processing and 3D simulations it is very helpful

I used it for my post-processing mostly and i have given introductory lecture to students.

Ansys Cfx is a very simple looking program- with power. The simulations are easily set up and you can check the results fastly.

Some empirical constants/variables are not explained in the documentation, so it's a try and error.

It's way better than fluent.

Cavitation Modeling- there are several mathematical models on that.

The name of the function I need to use in the fluent module is itself a self-explanatory. I do not need to learn this tool from someone else.

For the 3-D model with the high number of grid point, it requires huge time to run and also need high memory. I understand that it's the requirement for this tool. However, this is the thing which mostly irritating me.

I used to analyze the CAD model and observe the fluid behavior over it. So, mostly I used it to solve the CFD problem. The useful thing is its shows result in different color codes.

The simulations obtained are very advanced, showing great results in the movement of fluids in the different states from which an understanding of their movement dynamics is required. I had the opportunity to perform fluid analysis in convergent-divergent nozzles for the study of shock waves that occur in supersonic flow and obtained impressive and illustrative results of the thermodynamic properties that occur in such flow.

Many times errors occur in modeling that are not easy to detect, and generally not much help is available to start using the software, which is a bit annoying at the beginning. The processing requirements are a bit high, so a good computer is needed to run the simulations.

As an Engineer, I recommend this software to all students and professionals who need to perform fluid simulations for their dynamic and thermodynamic analysis.

At the university, we solved many problems in Incompressible Flow Dynamics, especially in convergent-divergent nozzles, and thanks to ANSYS, we were able to learn about the study of shock waves that occur both at the exit of nozzles and inside them. As an engineer, it is very beautiful to be able to observe how the dynamics of fluid movement occur, and with ANSYS, this becomes possible in a clear and efficient way.

It is efficient and we can solve complex models in less time with accurate results. It runs robustly for all fluid flows I. E., Steady state, incompressible, transient etc.,

Needs more time to simulate the model. Software cost is high and liscense problem

It's a convenient software package for CFD and Heat Transfer Areas.

Fluid dynamics problems in case of aerospace. Discretization the component into multiple bodies is easy. High resolution.

.its a great tool to analize 3d data for propolsion and powertrain

the tool needs automation for generating reports

I use the software to run cae analysis for atomizer performance
