Report from the First Brazilian Congress on CFD

by Luiz Fernando Lopes Rodrigues Silva, Wikki Brasil

The Brazilian Congress of Computational Fluid Dynamics (CBCFD 2016, http://cbcfd.com.br/) took place in Campina Grande, Paraíba, a state of the Northeast region of Brazil. The congress lasted three days, from 11th to 13th of June 2016, when participants from academia and industry had the opportunity to discuss about several topics related to CFD. Considering this, representatives from important CFD Brazilian companies and universities could gather in CBCFD, as Embraer, ESSS, CD-adapco, ATS, Wikki Brasil, UFRJ, Unicamp, UFCG, UERJ, UFF and UFSC, just to name a few.

Opening Session

The activities of the event included oral and poster presentations, lectures on general topics, round tables and short trainings. The works presented in CBCFD showed developments on different fields, such as aerodynamics, multiphase and reactive flows for instance. Also, the works used a vast range of CFD and mesh generation softwares, as Pointwise, ANSYS Fluent, and OpenFOAM to show a few.

In addition, it was not random that CBCFD 2016 coincided with one of the most famous Brazilian cultural festivals from the Northeast region of Brazil. The CBCFD participants could experiment typical food and see regional dance and arts at the biggest “São João” Festival of the world.

It was the very first congress specifically related to general aspects of CFD in the Brazilian territory and it turned possible to gather nearly 300 participants. As such, Wikki Brasil and Pointwise contributed sponsoring the congress and providing a hands-on training on mesh generation. The next edition of the CBCFD is scheduled for 2018 somewhere in the Southeast region of Brazil. Rio de Janeiro or São Paulo? Place a bet and see you there!

4. Talk CFD with our Partners

Believe it or not, meshing is not an end unto itself. Your CFD toolset needs complementary products for an effective workflow. You’ll have plenty of time during the Pointwise UGM 2016 to meet and talk in detail with some of our partners about their solutions.

  • ENGYS
  • Intelligent Light
  • Metacomp Technologies
  • Optimal Solutions
  • Tecplot

5. Come Because Monica Says So

In writing about SolidWorks World 2013, Monica Schnitger eloquently made the case for attending software user events. Let me quote her directly:

“Do it. Even if you’re not a joiner, go. Even if you don’t think you have anything to offer (you’re dead wrong, you do), go. Even if you didn’t organize it, go. Trust me. It’s very rarely not worth the effort and often you get out far more than you put in.”

You can read the rest of her words in The Power of Community.

6. Did I Mention It’s Free?

We don’t charge a fee for attending the Pointwise User Group Meeting. So that’s one less thing you have to justify to your boss. All we ask is that you register in advance.

  1. Register today.
  2. Book your hotel tomorrow.

7. Enjoy Some Texas Hospitality

Fort Worth in late September is a wonderful place to visit. Average temperatures range from 67 F for the low to 87 F for the high. Downtown Fort Worth, where the Pointwise UGM will be held, was recently named the best downtown in the country. And you get two parties: a welcome reception the first night and an after-party on the second night.

8. Get a Glimpse of What’s Planned for the Future

You’ll have the opportunity to hear several presentations from us at Pointwise not only on the current state of the CFD world and what we’re doing today, but where we see CFD and meshing going in the future. We’ll talk about how our vision may manifest itself in our products, solutions, and services.

[Plus you never know what dang foolish thing I’m going to say so there will be plenty of opportunities for this.]

Hope to see you here in Fort Worth next month.

This Is How I Glyph – Split Connectors At Their Intersection

SplitConsAtIntersection

Pointwise was exhibiting at AIAA’s Propulsion & Energy conference this past summer in Salt Lake City, UT when one of our users visited our booth at the conference with a question about how they could split two intersecting connectors at their point of intersection.  Astute readers will know that this capability isn’t readily available in Pointwise.  At most, one can select both connectors, and estimate the location where they are split using the cursor in Pointwise’s Split Panel.

This got me thinking that perhaps a Glyph script could be written to accomplish this task.  Pointwise can find the points of intersection of two sets of database curves via the Intersect… command found under the Create menu.  These intersection points could then be used to split the original connectors.  All that remained was creating the database curves from the original connectors.  This is exactly what the script I ended up writing does.  Of course, after I had written the script and forwarded a copy to the user originally requesting this capability, I noticed that we already had written a script that does exactly this and is hosted on our Glyph Script Exchange!

Sometimes workarounds exist via Glyph scripting that provide functionality that isn’t currently available in Pointwise.  Likely someone at some point has had a similar need and worked through a solution already.  If so, then they may have decided to share it on our Glyph Script Exchange.  It’s certainly worth checking out before setting out on a new scripting adventure…

Both scripts are now available at the project’s repository hosted on GitHub.  You can use this link to download the GUI-driven version of the script.  If you’re interested in the alternative script I wrote without the Tk graphical interactive elements, then you can download that version using this link instead.

If you have an idea for a new Glyph script, and you would like to learn more about how to get started, then contact us via the comments section below or contact @Pointwise on Twitter.  We’re also interested in learning more about the Glyph scripts our users have created.  Get in touch with us if you would like to share and have your script highlighted here on Another Fine Mesh.

I’m Andrew Jefferies and This Is How I Mesh

AndrewJefferies

Andrew Jefferies, Business and Administration Services Summer Intern

I was born in Tucson, Arizona, to Mike and Carrie Jefferies. My life is kept in constant chaos and fun due to my three younger sisters – Audrey, Abbey, and Ashley. When I was seven years old, my family moved from Arizona to Fort Worth because my dad had been hired here at Pointwise, Inc! The Crowley Independent School District was my home from that point on through high school, and I really enjoyed my experiences there. Upon graduating, I attended a year of college at Oklahoma City University and absolutely loved it. I then left to serve a two-year mission for the Church of Jesus Christ of Latter-day Saints in Spokane, Washington.

My mission just ended in June of this year, and I immediately began working as a summer intern here at Pointwise, Inc. I take care of scanning and shredding older, important documents in addition to any other needs that arise – addressing envelopes, moving and unpacking boxes, cleaning up after lunches, etc. On average, I shred about seven trash bags full of paper every week!

I’m very familiar with Pointwise, Inc. due to the fact that both of my parents also work here. Coming to work here upon returning from my mission was a thrilling prospect and a huge blessing. It has been an amazing opportunity to work in such a wonderful environment and to see some of the inner workings of an established business.

Most of my life has been devoted to my passions for singing and acting. Later this month, I’ll be transferring to Brigham Young University to study musical theatre. Working at Pointwise, Inc. this summer is assisting me in following my dream.

  • Location: Fort Worth, TX
  • Current position: Business and Administrative Services Intern
  • Current computer: Dell Precision M4400 laptop – “Yeats”
  • One word that best describes how you work: Focused

What software or tools do you use every day?

In addition to my laptop, on a daily basis I use the Canon Copier/Printer iRC3480 nicknamed “Happy” and the Fellowes 99ci Shredder. On my laptop I use the program Outlook to access my email and the instant messaging program Spark to communicate with my co-workers.

What does your workspace look like?

AndrewJefferiesWorkspace

Andrew’s current workspace

Clean and organized! I have two desks that fit in the corner of the office, which I attempt to keep pretty spotless. The shredder sits behind my desk for easy access. I also have a short filing cabinet to the left of my desk to help keep my workspace organized.

What are you currently working on?

I’m currently going through the archive of old payroll and 401(k) records, making sure that they have all been copied digitally using the scanner, organizing those files on the computer, and then shredding the hard copies. It may sound simple, but it certainly is time-consuming!

What would you say is your specialty at Pointwise?

My specialty at Pointwise is following orders. I’m not very experienced in the Business and Administrative Services side of a company, and I have zero experience with engineering computer software. This summer I’ve learned to take notes and closely follow the directions I’m given in order to make others’ jobs less difficult.

Any tips, tricks, or advice for our users?

Anyone who has interacted with me while working at Pointwise, Inc. knows that I am almost constantly listening to music as I work. That’s what I do to keep myself entertained and happy! Spotify has become my best friend. So listen to music while you mesh.

What project are you most proud of and why?

At this point, I’m most proud of my work cleaning up and organizing the many boxes of records and books on the shelves in the office. It’s much easier to find records now, and the shelves look very clean and professional.

Also my manager, Rose Mary Crager, and I worked really hard in order to make sure that all of the information for our assets matched across all of our books. That project took a lot out of me, but we both felt pretty accomplished once it was completed.

 Have you recently read any books or articles we should know about?

If I’m completely honest, I haven’t read anything related to meshing, but if you’re interested in reading about religion or musical theatre, I have some wonderful websites that I use frequently for information and inspiration – lds.org and broadway.com!

What do you do when you’re not surrounded by engineers making meshes?

Like I mentioned earlier, my greatest passion is musical theatre – and nearly everything I do is geared towards that. Listening to music, singing, playing the piano, and acting in shows are some of my favorite pastimes. Starting in high school, I became very involved in the theatre program and the productions they put on. Eventually I decided that I wanted to pursue a career in that field, and chose to attend Oklahoma City University for a year due to their acclaimed program. In all, I’ve performed in eight musicals, eight plays, and three operas. I also love spending time with my family and going to church.

What is some of the best advice you’ve received?

Dr. David Herendeen, one of my directors at Oklahoma City University, would often say to his students, “It isn’t your fault, but it is your problem. So what are you going to do?” I’ve found that as I focus more on what I can do, instead of what’s happened to me, I’m able to accomplish much more.

If you had to pick a place to have dinner, where would you go?

Panera Bread sounds really great right now. I would probably get a sandwich and salad combo – something delicious that won’t make me feel super guilty after eating it!
