If it was possible that anything could be 100% pure, drawing gas out of the ground could be a piece of cake. Gas, unadulterated by any other substance could travel easily through the pipes without damaging a bit of the structure designed for its capture. Unfortunately, this isn't how the world works.

All three states of matter are represented in the process of extracting natural gas from the earth - solids (sand) and liquid (water) come along for the ride. This wrecks havoc on the pipeline, especially at T-junctions and choke valves. Sand banging against flow obstructions causes corrosion which ultimately leads to economic and production losses.

It's become a bit of a cliche to say that our latest Conference is the "most successful ever", as these things tend to grow organically from year-to-year. However, having attended over 20 STAR Conferences (as both as customer and employee of CD-adapco), I can honestly say that SGC14 was different. Not only was it our biggest ever conference (with well over 500 participants from every corner of the globe), it also featured the most diverse collection of simulation success stories we've ever heard.

Speaking to the STAR Global Conference 2014, in Vienna, President Steve MacDonald reveals that CD-adapco is working to add a Finite Element solver to STAR-CCM+.

An intern joined our team recently. Fresh out of college, he was tasked with finding best practices for a particularly complex nozzle application. The internship was only to last a few months, but our new colleague was keen on showing the "real" world what he could do. With his new CFD toolset, he set-up the complete analysis with a full-blown-reacting-flow-on-the-real-geometry case - on day three... On day four, he was looking nervously at the screen wondering why his residuals continued to climb and the case did not converge.

I am pleased to announce the availability of STAR-CCM+ v9.02 on The Steve Portal!

My objective when we started to discuss the list of features and enhancements for the STAR-CCM+ v9 versions was ambitious. Clearly, adding realism to the simulations, enhancing workflows, increasing throughput and improve accuracy all at the same time was truly a challenge and I believe our development teams succeeded one more time in delivering it.

One of the greatest challenges of engineering analysis is the ability to understand how changes in geometry and flow features might influence your system’s performance. For a long time, the only way to gain insight into the sensitivity of engineering objectives to changes in input was to run multiple analyses and then dig through the results. The introduction of the adjoint solver in STAR-CCM+ v8.04, however, changed that - allowing for direct access to sensitivity information from a single simulation.

Volume rendering, a well-known scientific visualization method, is being introduced with our latest version of STAR-CCM+! (v9.02)

This February we announce the release of STAR-CCM+ v9.02 and one of the most exiting features to join the wealth of multiphase capabilities in this release is the Dispersed Multiphase (DMP) model.

The simulation of applications such as aircraft deicing/anti-icing, and vehicle soiling and water management will now take a fraction of the time with the new Dispersed Multiphase (DMP) model in STAR-CCM+ v9.02.

I was recently traveling to a User Conference that CD-adapco held in Asia and spent a great deal of time staring out the window of various aircraft. With several hours to contemplate wings, I started thinking about boundary layers and how I have been simulating them. After reading “Boundary Layer Theory” by H. Schlichting, I had to double-check to make sure my designs were modeling the fluid phenomena near the wall correctly. What we design is far from well-known and validated fluid dynamics test cases. In fact, we invent some of the most unconventional products.

The other day, Dr. Design came to me with a new project: “We must find the drag coefficient of a futuristic vehicle concept!!”

As usual the deadline was yesterday. With the CAD in hand, I started to set up my simulation. I had to say, the meshing part was easy. I arrived rapidly to the point of setting up my boundary conditions, but here's where I ran into some doubt. How should I model the rotating tires?? Yes, the vehicle is futuristic, but not electromagnetic yet. I could see a few methods… Which one should I choose?
