The goal of the trial is to enroll 20 patients at 6 clinical sites. Dr. William Abraham of Ohio State University and Dr. Patrick McCarthy of Northwestern University Medical Center are the national co-lead principal investigators. Trial locations and eligibility requirements can be found here.

In my previous post on simulating devices and treatment for the human heart, How Do You Mend a Broken Heart , I mentioned how Sunshine Heart’s life saving heart pump is intended to be used in patients with moderate heart failure as an alternative to open heart surgery.

The heart pump can be implanted in a patient in a one-hour operation with no blood contact, which offers the potential of lower complications and costs. The decreased risks make the C-Pulse available to a larger group of patients.

You can view the U.S. news casts with patient testimonials and learn more about the how the pump works at Sunshine Heart’s website.



Green Oil? A View from Offshore Europe 2009

We all consume energy every day with almost everything we do. And like energy companies, we need to ask ourselves – can we be more efficient?

This week, our SIMUILA UK team has been exhibiting at Offshore Europe in Aberdeen, the second biggest oil and gas trade show in the world.  There are several hundred exhibitors and over 30,000 visitors at the week-long conference.


While protecting the environment is on everyone’s mind, the slump in oil prices means it’s more critical than ever for energy companies to tap into energy resources more cost effectively.

BP and BG announced massive new oil field projects prior to the conference. But while they must contain exploration and production costs, they can’t cut corners on safety, especially when extracting oil from greater ocean depths.

How do these companies and others know their equipment will work reliably in harsh offshore conditions without overspending and causing delays by relying solely on physical tests?

By innovating with Realisitc Simulation.

SIMULIA is helping Oil and Gas companies like Weatherford improve the design their Expandable Sand Screens and Prospect to virtually test their latest products before making a prototype. Abaqus FEA is used to analyze realistic performance of many critical parts and systems for energy exploration including filters, pipelines, foundations, pressure seals, and more. By trying out their designs virtually, they are able to evaluate structural integrity without wasting time, cost, and energy on multiple physical prototypes.

These savings can have a big influence in the price you pay at the pump when filling up your vehicle.

A topic crucial for our environment is moving oil through pipelines while preventing leaks or spills.

JP Kenny has used Abaqus on many projects including evaluating the best way to lay underwater pipelines in the Arctic while preventing them from being damaged by iceberg gouging. You can check out their case study at Offshore Magazine’s website.

It’s also worth remembering that Offshore Energy is not all about oil – with E.On launching Scotland’s first offshore wind farm this week – it seems all energy, even oil, can be green as well as black.

Ohio Drivers May Paint Local Bridge FEA Red

Hi everyone,

First, welcome back from your summer adventures! I’m surfacing after some time away and getting back into the ‘back-to school’ swing. This weekend I was catching up on some emails and came across an article that tickled my fancy. Impassioned Ohio drivers getting worked up about a local bridge on the verge of collapsing.

Looking at the ensemble of article + 19 comments, it seems that the bridge shows signs of degradation, yet the state transportation department has been pouring resources into the construction of new roads.

Until the 3D FEA analysis software was tapped.

Abaqus FEA software, also used for complex engineering, innovations in diapers and even the study of bed sores, has helped the ODOT scientifically conclude that indeed the bridge is on the verge of failure. So rather than enhancing the existing structure as originally planned, they’ve determined it’s more life-and-cost-efficient to eliminate the current bridge and start anew.

“No duh” say some of the local citizens, and they’re pushing hard for construction action now, rather than waiting until 2014.

One of the commenters suggests they literally paint the FEA analysis onto the bridge to show exactly where the red-zone’s located (red being the crumble danger zone), hopefully garnering immediate action. ;-)

And there was even someone that shared wish lists of color schemes and aesthetics for the new bridge.

Which got me to thinking: Ohio, why not go further than the FEA analysis?

You can share a 3D model of the new bridge design and have citizens vote online for their preferred colors, surrounding vegetation, etc.

You’re lucky to have active citizens who care about the bridge; get them involved in the project with other flavors of the same 3D software that helped you confirm your action plan.

Now that’s democratic !
