Fundamental CFD Tutorials to Teach and Learn CFD Simulation Development in STAR-CCM+, FLUENT & Open FOAM (SFO-Project).

[teymourj]

Dear all,

University of Washington's Fluid Mechanics group in department of Mechanical Engineering is proud to present the new generation of methodological CFD tutorials under direct supervision of professors Alberto Aliseda, James Riley and myself (Teymour Javaherchi).

We recently presented the scope of this project at APS-DFD 2016 meeting in Portland. The presented tutorials of this project are great source to learn and teach development, implementation and validation of CFD simulation based on first principals in three main CFD solver of our filed; Star-CCM+, Fluent & OpenFoam (SFO-Project). This project has been developed by team of post-docs, graduate and undergraduate students and is moving forward actively. All of the finalized tutorials are publicly available on SFO-Project website (click here!).

Our excited and motivated team is ready for any potential collaborations with your side:

• Developing public or private case studies for your application and/or CFD course.
• Translate/Share your previously developed and validate CFD methodologies via SFO-Project format.
• Provide consultation for the researchers and contributors of the field.
• Developing suggested case studies of interest.
• Receiving your feedback and suggestion to improve the quality of the project.
• and many more!

Please don't hesitate to contact our team directly via Email. We look forward to hear back from you soon!

Cheers,

SFO Team :)

Thanks Teymour. Lots of good information on your website and I thank you and your team for developing the website and making it available to others. The only thing lacking from my point of view is videos with detailed step-by-step instructions (with voice) about how to actually set up and run the software packages. I have been doing exactly that lately. (I assign these as homework problems in my classes, and the students can learn enough from the videos to solve the problem – even first time CFD users, which includes most of my students.) You are welcome to link these videos onto your website if you want. I also attach the actual HW assignments that I give to my class that go along with these tutorials.

 

I also remind you that there are many CFD tutorials on the SimCafe website of Cornell, which most of you probably already know about. Their website is https://confluence.cornell.edu/display/SIMULATION/Home . Cornell also offers a MOOC about simulation which has been very popular.

 

Anybody on this email list is welcome to use my HW assignments and video tutorials in your classes. All I ask is that you give the proper credit/reference to my grad students and me and Penn State University. More details about these tutorials and assignments are given below.

 

Flow between rotating concentric cylinders

My grad students and I created a video tutorial for flow between two cylinders where one or both of them is rotating. One nice feature about this assignment is that it can be solved exactly (analytically) and then the CFD results can be compared directly with the analytical solution. You will see on the HW assignment two different problems – one analytical and one CFD, and then they compare the two. We create the tutorial for this one only on ANSYS-Workbench.

 

ANSYS-Workbench: This tutorial was created by Matt Erdman under my direction, so the credit should read “Matt Erdman and John M. Cimbala, Penn State University”. The link  is:

Flow over a circular cylinder at low Re (but could also be adopted for higher laminar Re regimes)

Two of my grad students and I created video tutorials for flow over a circular cylinder. These are specifically geared towards low Reynolds number flow (we used Re = 2). It has three primary objectives: (1) Learn how to set up and solve a CFD problem. (2) Understand that at very low Reynolds number a body influences the flow very far away. Another way of saying this (from a CFD domain point of view) is that the far-field boundary conditions significantly influence flow around the body unless the far-field boundaries are very far away. (3) Quantify how far away the far-field boundaries need to be in order to no longer significantly influence the flow near the body. [Note that it requires a far-field boundary that is more than 500 diameters away! The students are amazed at how far away the boundaries had to be to achieve convergence.] I used this as a HW problem and gave students the option to use any CFD code they wanted, although we made video tutorials only for ANSYS and STAR-CCM+.

 

The tutorial videos are on YouTube.

 

ANSYS-Workbench: These were created by Skylar Schirtzinger under my direction, so any credit should read “Skylar Schirtzinger and John M. Cimbala, Penn State University”. Skylar had to split it up into three separate parts due to limitations on the video capture software he was using. The links are:

https://www.youtube.com/watch?v=EcpwcKA9OTQ&feature=youtu.be

 

STAR-CCM+: This video was created by Matt Erdman under my direction, so the credit should read “Matt Erdman and John M. Cimbala, Penn State University”. The link is:

Dear All,

Many thanks to Teymour and John for making their materials available. I have used John's ANSYS-based materials in the past and students had generally few problems following the written instructions at that time. Everything worked out really well in my undergraduate fluids/CFD course.

We have since switched to Comsol for funding reasons and we may switch once again to OpenFoam for the same reason. Please let me (and the mailing list members) know, if you are available of OpenFoam-based instructions (or any other teaching materials) similar to those John created for ANSYS. It's great to see OpenFoam modules included in Teymour's materials.

Thanks for any leads.

Best,  Frank

Dear all,

Taking a different approach on teaching foundations of CFD, I have also released my educational materials openly. They consist of a series of lessons that take learners step-by-step to programming from scratch a 2D Navier-Stokes solution of cavity flow and channel flow (in Python). The series is called "12 steps to Navier Stokes"

http://lorenabarba.com/blog/cfd-python-12-steps-to-navier-stokes/

The programming exercises are freely available on GitHub (released 2013).

To go along with this, I published a series of lecture videos (recorded live as screencasts) on YouTube. These are from the 2012 version of my course, after which I used them to continue teaching in a flipped-classroom mode.

Regards,

Lorena Barba

Dear all, 

I am very happy, pleased and honored with all of your valuable responses, feedback and inputs to this original post on the SFO-Project. Special thanks to Jean Hertzberg and Frank Jacobitz, who initially encouraged having this post in this group during APS-DFD meeting.

-John: We are in the process of recognizing the best approach to incorporate your CFD tutorial videos within the content of the SFO-Project. We will get back to you for further updates and feedback soon. Thank you so much for all your valuable inputs.

-Lorena: Thanks for sharing your website here. Our students at UW know your website very well. We have used the material among grad and undergrads as a unique and first-to-go platform to learn and perform CFD coding in Python. Related to the SFO-Project, the structure of your website and tutorials was one of the most valuable guidelines for us to come up with the current content storage for the SFO-Project.

-Rajesh: Thanks for your inputs and links as well. I personally start learning CFD from the very early version of tutorials on the Cornell University website :) The material that you share is one of my top recommendation for students who are starting to learn CFD.

- Everyone else who contacted me directly via Email or under the original post with suggestions and kind words; “THANK YOU!”. 

Our team strongly believes in the saying “standing on the shoulders of giants (You)”. That is what we are trying to do and the above-mentioned points are proof of that :) Hopefully, the integration of all these works and contributions, built on top of each other with different prospective and goal of filling the existing knowledge gaps in the field of CFD, will direct the teaching of CFD in a great, smooth and efficient path.

Cheers,

Teymour Javaherchi on behalf of SFO-Project Team

Dear all,

Good to know of all these teaching resources. My MOOC, that John generously mentioned, teaches both CFD and FEA in an integrated fashion from the point of view of the code user (rather than code developer). The tool used is ANSYS Student (available for free at ansys.com/student) but the teaching approach is tool independent. The MOOC is available for free at
  https://www.edx.org/course/hands-introduction-engineering-cornellx-engr2000x
Rgeistration on edx is required to access the MOOC videos. The MOOC is currently available in archived mode and will relaunch in self-paced mode on Feb. 15, 2017. 

You are welcome to use any of the MOOC modules or videos in your teaching for free.

@Frank: You and your students can use ANSYS Student for free. It allows up to 512,000 cells for CFD and 32,000 nodes for FEA. This is more than adequate for teaching.

Best,
Rajesh Bhaskaran

All,

Some of you may be interested in the webinar I am giving on this very topic this coming Tuesday. Forwarding details from Siemens CD-adapco:

Siemens PLM Software   How to add CFD into a fluid mechanics course Hosted by Siemens PLM Software, formerly CD-adapco     Webinar: December 13, 2016 • Available Times John, Faculty often want to add computational fluid dynamics (CFD) into their fluid mechanics courses, but don’t know how to make it fit into their already crowded syllabus. In addition, CFD class projects are sometimes limited due to learning curve challenges that involve the creation of geometries and meshing. Are there better ways to teach CFD techniques, especially to undergraduates? (Details)   Penn State professor John M. Cimbala, co-author of Fluid Mechanics: Fundamentals and Applications, will demonstrate how tutorial materials and videos can be combined with engineering simulation software to increase the understanding of basic CFD concepts while also enhancing students’ knowledge about fluid flow. Using class-tested materials and homework samples, Professor Cimbala will highlight proven teaching methods to prepare students for basic CFD modeling. (Details)   Guest Speakers: Tilo Winter, Lecturer, Technische Universität Darmstadt Professor John Cimbala, Pennsylvania State University   December 13, 2016 Pick the time that fits your schedule   Share This Event:

I forgot to mention that my talk is the one at 1:00 on Tuesday December 13. It is 20 to 25 minutes long with a time for Q/A at the end.

[John Cimbala]

All,

A few follow-up items from our recent e-mail thread on CFD education:

 

1.      Here is the link to the webinar I gave yesterday. My talk starts at about 19 minutes into the video:
http://mdx2.plm.automation.siemens.com/webinar/how-add-cfd-fluid-mechanics-course

2.      I attach a pdf file with the three HW problems that I discussed in the webinar. You are free to use these in your classes if you want, but please reference its source. The links to the video tutorials are also included in this file.

3.      The link to my CFD chapter (available only as an e-book) is:
https://create.mheducation.com/shop/#/catalog/details/?isbn=9781308993256
If that does not work, go to:
https://create.mheducation.com/shop and search for “Cimbala” and it should show up. It is the one entitled “Introduction to CFD and How to USE it”. As of today it is priced at $10.14, but I am trying to get McGraw-Hill to reduce it to $9.99 so that we can tell people it is “under $10”. [Disclaimer: I tried to make it available for free, but McGraw-Hill does not allow this due to copyright issues.]

 

Have a great Christmas/Holiday/New Year break everyone!

John
