Easily accessible. Easy to learn, since it's very well documented and has a lot of discussion forums. Also, the availability of source files, makes it easier to actually realize and appreciate its working and gives sense of control over it and helps in understanding the underlying computations and physics, rather than working on a "black box" which is the case with most of other tools of comparable capability.

I Started using OpenFOAM last semester in Feb, 2013. In the start, it took a while to get used to all the file system but later it became normal.Customization of problem's physics is very easy unlike other packages whereediting is restricted after a level.

I had never been introduced to OpenFOAM until last semester. So initially it took me some time to understand how to go about it, but once I got a hang of it, I could work well with it. The video tutorials were of great help.

I used OpenFOAM for my class assignment for "Turbulence and Combustion" in Spring 2012 at IITB, in which I asked the students to solve for turbulent channel flow at high Reynolds number using RANS (Reynolds Averaged Navier Stokes) models and compare the output with Direct Numerical Simulation data. I referred students to the FOSSEE spoken tutorial website for learning the basics of OpenFOAM, which they found to be very useful. One of the big advantages of using OpenFOAM was that the students could simply download the software into their laptops for free, and I did not have to worry about giving them access to any licenses. Moreover, the students were able to learn the software fairly quickly, and got a great hands-on learning experience on using RANS models.

My M.Tech supervisor asked me to learn OpenFOAM. At that moment, I didn't have any idea about this FOSS. I started with YouTube videos and found Spoken Tutorials of FOSSEE, IITB. They explained the basics of OpenFOAM very well. The Spoken Tutorials helped me a lot in the learning of this FOSS. Later, I got the opportunity to come to IITB for the FOSSEE fellowship program. I met the professors, mentors and the other fellows there.  They helped me to solve some problems on which I was facing difficulty earlier. So, my experience with FOSSEE was very good.

FOSSEE IIT Bombay provided me great opportunity to understand what CFD and OpenFOAM really is. I had the opportunity to apply OpenFOAM over INS Vikramaditya model and studied the multiphase pressure and velocity characteristics in the domain. The mentors Mr. Sathish and Ms. Deepa were very supportive. It was an overall fulfilling experience, and anyone looking for exposure should definitely apply.

OpenFOAM and FOSSEE are the key to access such an complex Engineering material. When I started using OpenFOAM, every commercial software seems easy and less detail oriented. OpenFOAM gives wide access to compile and modify problem, solver and data. Best part are Video tutorial and open access to reports and case study on FOSSEE website. After learning, anybody can contribute to develop software and to improve documentation by making real engineering problem case studies.

It is usually argued that OpenFOAM has a very steep learning curve. But with the IIT Bombay Spoken Tutorials, this learning curve can be tackled with relative ease. Unlike other commercial software, OpenFOAM is easily accessible, free of charge and setting up OpenFOAM is very easy. The availability of source code helped my dive deep into the numerical schemes used in any problem I was trying to solve. OpenFOAM comes with enough tutorials that help beginners who have difficulty setting up cases from the scratch.

The first time I started using OpenFOAM is not very back in the past. Before, I used to use ANSYS for my needs. It was hard to start learning OpenFOAM in the beginning. I slowly made progress by watching YouTube, spoken tutorials and some other documents available online. But once you learn OpenFOAM, you usually don't like anything else. It is more detailed and conceptual than any other CFD software. If anyone is hoping to skyrocket their carrier in CFD, then OpenFOAM is the best choice. We ordinarily do not find people working on OpenFOAM, especially in India. It is the FOSSEE that has taken a step forward to spread the name of this FOSS among the young minds of India. FOSSEE conducts a summer internship every year where talents from all over India come together and work together. The best thing about this internship is that candidates are chosen based on their capabilities, not GPA or college. There is a perfect working environment for excelling one's knowledge and experience. Give this internship a try if you love CFD. Keep FOAMing.

OpenFOAM is really a powerful tool to analyze complex problems in a really straightforward way. It took a bit of time to grasp the basics, but once that is done, one can further play along with it with any possible given situation.

FOSSEE and IIT Bombay is a good place to work, Dr. Shivasubramanian had really good problems for OpenFOAM and Sathish and Deepa were really supportive and guided us well through the process. I would recommend any beginner in CFD to use OpenFOAM. I appreciate FOSSEE's work in getting people to use OpenFOAM and other open source softwares.

My hands on openfoam

OpenFOAM is a unique tool to understand CFD and has been a perfect book to understand the foundational aspects of computational sciences. Unlike conventional methods that restricts us from venturing into the skeleton of the software, OpenFOAM gives us the advantage of exploring and manipulating the techniques involved as it is a openware and is efficient enough for innovations to be incorporated.

Fossee at IIT Bombay has been a good support in connecting many students to easy access and learning of computer thereby bridging the gap in computer litreracy in steps.The Fossee CFD module being OpenFOAM, have made a better link to computer literacy computational skills and underlying physics,thus completing the education picture.

My fellowship at FOSSEE had me exposed to the ways in which, developers can explore the soffware and students can change the education scenario through FOSS and Outreach.

I’ve been using OpenFOAM for my final year project and I gained some experience through my project, but I lacked a community which supports and helps to learn OpenFOAM. FOSSEE gave what I was lacking, it provided a platform for learning and sharing knowledge. I got to meet lots of people who are interested in OpenFOAM from different parts of India. A great thanks to Mr. Sathish and Ms. Deepa for being our mentor and Dr. Shivasubramanian Gopalakrishnan for guiding us through the fellowship.
