How Retired Chemists Handled a Talk on Computer Modeling

Posted on May 17th, 2010 by Masha Petrova

Dear Readers,

Very sorry for such a long absence from this blog! I recently came back from an ACS (American Chemical Society) speaking tour, which was a very interesting and enriching experience for me. Currently, I am working on a couple of potential book proposals as well. There might be an upcoming opportunity for you to contribute to a book on a subject related to chemical kinetics and computer modeling. So stay tuned!

This was the first time I have gone on an ACS speaking tour and it was a very interesting experience. I would recommend it to anyone looking to grow as a professional in a technical field.

This is how the volunteer speaker service works: ACS puts together a list of experts in various chemical fields who would like to volunteer to be traveling speakers. Various ACS local sections then go through the list and choose which speakers they would like to invite to a specific local meeting.

If you are one of the speakers who has selected by a particular group of local sections (a circuit), you get to travel around that area for a week and present a new talk each day in a new location. I did not realize that the more options for talk topics you provide, the more likely are the chances of various locations picking different topics :) . So I ended up giving 6 talks in 5 days on 4 different topics. My circuit covered a good portion of Wisconsin, which turns out to be a relatively large state, so I had 3- 5 hours of driving in between different locations.

In case you’re interested, here is what my schedule looked like:

Monday, April 19, 2010

Location: La Crosse, WI

Venue: University of Wisconsin - La Crosse

Topic: Economic Crisis and the Need for Computer Modeling

Tuesday, April 20, 2010

Location: Milwaukee, WI

Venue: ACS Annual meeting

Topic: 10 Ways to Increase Your Value

Wednesday, April 21, 2010

Location: Appleton, WI

Venue: Lawrence University

Topic: A Wife, a Mother, and a PHD

Thursday, April 22, 2010

Location: Stevens Point, WI

Venue: ACS meeting + university campus talk

Topic : A Wife, a Mother, and a PHD and Economic Crisis and the Need for Computer Modeling

Friday, April 23, 2010

Location: Houghton, MI

Topic: Importance of Perception - Why You Should Care About What Others Think

During each presentation I had a completely different audience. One day it was a large group of students. Another day it was a small mix of professors and graduate researchers. Yet another day I presented to a mixture of chemists from industry and academia.

One of my favorite audiences was in Eau Clair, where I presented the “Computer Modeling” talk to a group of retired industry chemists. Considering that half of my audience has never used a computer for so much as e-mail, it was an interesting presentation. But I have to say the retired chemists were one of the most inquisitive and interested audiences I had on this trip!

Going into the talk I had a bit of a panicky moment. Some of these people have been doing experiments in the lab for longer than two of my lifetimes. How in the world was I going to explain to them that we are on the path of moving more and more of these experiments into this teeny box called a “computer”?!

Amazingly, my audience stayed curious and interested through the whole talk. Afterwards, some of the listeners shared a few stories about how back in the day, you had to use stacks of punch cards to program just a few lines of code. Maybe because the have seen such evolution of science and technology over their lifetimes, the idea of more and more experiments being done virtually, inside of a computer did not seem surprising to them.

Now if only I can have such an open-minded audience at TurboExpo next month!

Computers, Kids and my Fear of the Future

Posted on February 11th, 2010 by Masha Petrova

I am thoroughly disturbed. I just finished browsing through the technology magazine section of my local Barnes & Noble. A common theme ran through most of the magazine articles that I found rather unnerving.

“Can we trust robots? New models that will talk, act and look like humans…why experts are worried.” in Popular Mechanics.

“The mind readers – Scientists who can pluck images from your head” and “Cyborg Spy-Bugs! Terrifying Science or Innocent research?” in Popular Science.

“Robots – real-life androids that fight wars and save lives” in How it Works.

I realize that these are not peer-reviewed scientific publications, but the information in these magazines does reflect the state of current technology research. This, to me, makes reading about computers that can hack into our minds, remote control robots the size of an ant, and artificial intelligence that can mimic human thought, rather creepy.

CKS continued and Intro to cool new tool: Sculptor

Posted on January 19th, 2010 by Masha Petrova

Talking about what’s new at MVP and more info on CKS software from IBM. (Cant see the video? View it on YouTube: http://www.youtube.com/watch?v=oxb11X61WGo)

(for more on CKS see this post)

Brief Overview of Sculptor from Optimal Solutions

http://www.optimalsolutions.us/

Today, I want to give a brief background on a cool software tool, called Sculptor from Optimal Solutions. The guys at Optimal Solutions were very helpful in providing me with a webinar and demo of Sculptor in real time. (Thanks John and Taylor!)

Disclaimer for this post: This is not a full review but simply a brief introduction to the software. To learn more, visit http://www.optimalsolutions.us/ .

So what is Sculptor? From Optimal Solutions website:

“Put simply, Sculptor is shape deformation software. It can arbitrarily deform the shape of a computerized object whose shape is defined by the points of a grid. The grid is defined by a CFD [or an FEA] code”

One of the features of Sculptor is its’ geometry optimization ability. Figure below demonstrates really well how this software can save a lot of time and money during the engineering design process.

Figure courtesy of Optimal Solutions:

Sculptor Optimization Process

Sculptor takes out the need to go back and change geometry in CAD itself. The engineering design process becomes much more efficient, since the optimization feedback loop is now much shorter and less complex (see figure above). In addition re-meshing in CFD or FEA is not as complicated as changing geometry in CAD.

The engineer at Optimal Solutions told me that Sculptor works with virtually any CAD, CFD, and FEA software available.

This is a tool designed to save engineering time and company money, while making the design process more effective.

On Teaching

Posted on December 21st, 2009 by Masha Petrova

I just found out that my American Chemical Society courses have been officially added to the ACS spring schedule:

American Chemical Society

Computer Simulation of Reactive Flows: http://www.proed.acs.org/courses/course_overview.cfm?course_code=RFWEB

Essentials of Chemical Kinetics: http://www.proed.acs.org/courses/course_overview.cfm?course_code=KNWEB

This inspired me to write on the subject of teaching – specifically, why most engineering courses are taught in such boring ways, and what can be done about it.

Reactive Systems Solvers: Stochastic approach vs. Integrator

Posted on December 2nd, 2009 by Masha Petrova

Hello all,

Happy, though rather belated, Thanksgiving. Hope everyone enjoyed a good meal and time with family.

I was traveling all last week and am just digging myself from underneath work that piled up during my absence. So I apologize for not getting a post up last week.

Recently I discovered a software tool for chemical kinetic modeling. It’s called the Chemical Kinetic Simulator (or CKS) from IBM Almaden research lab. The code has not been updated since mid-1990s, and I probably would not have given it much thought except for an interesting feature of this software.

The authors claim that CKS does not integrate sets of coupled differential equations to predict the time history of a chemical system. Instead the code uses a stochastic algorithm (type of Monte Carlo calculation) to propagate a reaction.  The authors claim that the stochastic method is much faster for stiff systems.

The  question is, if the stochastic method is much faster for solving reactive systems, why are most other software tools (e.g. Cosilab, Chemkin, DARS, FlameMaster, Chemical WorkBench) use solvers that integrate coupled systems of equations instead of using some form of a stochastic algorithm to solve chemically reactive systems?

I am determined to figure it out. In the next week I’ll be doing some research on the two solver methodologies , the CKS code and other related software. If you are dealing with anything that is chemically reacting,  stay tuned!

On the other hand, if you have some information on CKS OR stochastic vs. integrator methadologies that you would like to share with our readers, either comment below or contact me directly: masha@mvpmodeling solutions.com.

I will be sure to give due credit to everyone contributing information!

Best,
Masha
