Ansys Fluent

Basic

Ph.D. Eng

Among the best features that have been implemented in the latest versions is the "Named Function": a tool inside the solver part that allows to define mathematical functions, and much more, in order to bypass the use of UDFs which is always a bit difficult and not easy to understand.

Its complete documentation and well-described equations make it a valuable asset for any project, especially those involving multiphase flow simulation or critical flow of gas through tight restrictions. Despite these limitations, I still believe that Ansys Fluent is a valuable tool for simulating complex systems.

Engineering Student

From mass, heat, and energy transfer, to temperature, velocity, and pressure gradients, Ansys provides a wide range of high value results for engineers to analyze and take educated decisions.

Ansys Fluent is especially helpful for simulating multiphase flows, such as gas-liquid interactions, and for modeling critical flow of gas through tight restrictions.

Research Engineer

Highly specialized algorithms for diverse geometry and calculation strategies, allowing multi-physics problems could be solved easily without over consuming your hardware resources.

Engineering manager

Comprehensive physics modelling,So very helpfull.

Student

Furthermore there is a help icon below each and every button which allows and opens up a browser which provides an in-depth analysis of the same.

I was able to import models from Solidworks and provide a comprehensive fairly accurate representation of my CFD projects and final year research project

Offers wide range of physical modeling capabilities, including fluid dynamics, heat transfer, and chemical reactions.

Computational Mechanic Team Leader

Ansys fluent provides the opportunity to easily solve multiple physics problems in different physics situations with flow simulations.

The software, in the Workbench functionality, allows to decide the type of module to use depending on the physics to be solved.

ANSYS provided me with the ability to develop high quality simulation models for heat exchanger projects while at university.

Legal Assistant

It has countless features and cover every aspect of simulation you could think of: fluids, batteries, optimization, etc.

Application Engineer

The fact that its price is much higher than its competitor makes customers put Ansys Fluent as a second choice.

Project Engineer

Another thing I like about using ANSYS is, it simulates the battery performance both, over the molecular and module level.

Helping us to save an enormous amount of time and effort in understanding and predicting complex phenomena, Ansys seems like a must-have for engineers of our era.

Thanks to its ease of use it allows a fast progress of the works, which allowed me to publish several scientific-numerical papers.

Overall, I have been enjoying solving fluid problems using Ansys Fluent since 2019 and I would recommend this to my colleagues.

Software Engineer 

Through this software we can integrate all types of engineering data for simulation.

Exporting data is very easy since you prefer to use another software viewer or perform numeric post-processing operations with Matlab as an example.

Engineer

It allows you to assess a lot of situations with different level of details.

Researcher

It also offers engineers and researchers a lot of flexibility in terms of equations (flow, energy, and turbulence) and boundary conditions to setup the simulation as customizable as possible.

Energy & Free Innovation R&D Programs Leader

ANSYS Fluent gather most of physical phenomenums to correctly models our various processes, and the possibility to add our own models allows us to perform specific simulations.

ANSYS Fluent proposes an efficient post processing tool, and link is possible with 3D virtual reality devices to enter directly inside the modeled system to see each details of results.

It is very intuitive to import external CADs into the geometry module and prepare the mesh accordingly.

Overall, ansys fluent has made a direct impact in my day to day work, allowing me to uncover various observations.

Senior software engineer

The ansys software provides accurate results in analysis of components.

Master Thesis Student 

Fluent is design in step by step manner like meshing, parameter design, Boundary condition, initialization, simulation and results.

The interactive user interface allows user to navigate through the options at ease and tutorial support offered gives additional boost to new entrants in the software

I particularly like the variety of data and model file extensions it supports; for example, you can import data from Excel and SolidWorks or cad files.

Modifications cannot be performed in the middle of the process, entire analysis should be performed again from the start.

In particular, among the different choices for the fluid dynamics part, there is Fluent, a Finite Volume solver.

Freelancer

One of its advantages is that it provides acceptable and satisfactory outcomes that are accurate and close to the experiment.

The simulation consumes a lot of time and hardware RAM to provide results.

However, it's important to be aware of its limitations and potential challenges in order to make the most of the software's capabilities.

PhD Student

Most of the time, the answers are actually more questions, which rather point on to 1 or 2 simple things or, a new question alltogether, making the whole process of going to the forum, quite useless. And if by any chance, the question is tricky enough, they direct to open the ticket, which takes another god knows how many days, with response that "I will get back to you soon" and this soon comes withint 1 month or so, not with answers , but with more questions.

Postdoctoral Researcher

Overall, Ansys Fluent is an incredibly useful tool for simulation, but it comes with a steep learning curve. If you're willing to put in the time and effort to learn it, the results are well worth it.

It requires heavy computational power to provide accurate results.

Our organisation has derived several benefits with Ansys, and it integrates well with most of the modelling softwares and PLM platforms.

Also the solver capabilities are very advanced and offer high accuracy.

Postdoctoral Fellow

However, for someone who is not researching in CFD but using it as a design tool, Fluent is way more user friendly at the cost of research level customizations to tweak problem setups.

Variety of files can be saved and get by Ansys software which includes excel, csv, pdf etc.

The interface is smooth and is kept up to date to the modern industrial problems, but some times the frequent updates of software keeps the simulations run in the earlier versions unviable.

You would first comprehend the relevant variables in order to achieve the required result.

ANSYS Fluent is a leader in CFD simulations.

It’s not for everyone to use (expert can get the best out of it, so it requires time to learn it properly).

Content Writer

One of the major disadvantage of this particular software is that  it consumes a lot of space on the RAM/ memory of the PC.

Additive Manufacturing Engineer

From geometry, through meshing, physics, solution and to results, the chronological order of the workflow makes Fluent easy to use, even for beginners.

There are minimum requirements to install and run Ansys generally but at times, even those minimum requirements seem to be incapable of a ensuring a smooth run.

The training portal, is also suppose to be self-explainatory with the new versions of pdf, however, it sometimes seems, the pdfs were never updated, and I wished again for Star-CCM+.
