Inspired by Simon Fischer and its “10 secrets to a stunningly fun CFD simulation“, we decided to explore our Simcenter Amesim archives and extract the most exotic, weird, funny, yet useful simulations we ever did! You might ask yourself: “Why did they even spend time on this?” or “How hard was it to get results?”, so did

Defeature and midsurface geometry quickly
One of the main issues you face as an analyst is the need to clean, defeature, and mid-surface geometry you import from CAD. Features like small holes, small steps, and surfaces impact meshing speed and quality but can be irrelevant to engineering performance. You might also have to create mid-surface geometry for thin-walled solid geometry
Composite Materials Performance Evaluation – using a fast, virtual testing tool
Industrial Challenge: Materials Engineering for Composites subject to Variability The powerful combination of being strong and lightweight makes composites materials favorable for the automotive and aerospace industry. This low weight translates into a reduction in fuel consumption and emission. Composite materials are more complex than metals, with more design parameters. A robust design is desired,
Inverters: the heart of electric vehicles
The electric vehicle inverter is an essential organ of the powertrain, yet it is often overlooked compared to batteries or electric machines. Looking at this study from NAS (2010), it is the most expensive PHEV component, second only to the battery. Based on this, it must be carefully engineered. This is what is described in
Digital Image Correlation (DIC) for Aircraft GVT
A ground vibration test (GVT) aims to characterize an aircraft’s structural resonances experimentally. This is an important step in the aircraft certification process. It helps validate the models used for aeroelastic prediction and verify that no flutter occurs within the flight envelope. Challenges in aircraft instrumentation during GVT Instrumenting the aircraft for this test can
Serving a perfect Guinness – the CFD way
It’s St. Patrick’s Day. And probably a St. Patrick’s Day like no other. Pubs around the globe are closed, bartenders are stuck at home, beer lovers forced to have their pint in isolation, the Irish folk is forced to celebrate without their mates. The perfect pour Now, there’s not much we all can do about
Perseverance: what’s the weather on Mars?
On February 18, we witnessed the amazing feats that scientists and engineers can achieve with Perseverance Mars rover’s perfect landing. I was watching the landing on a video feed from NASA with my seven-year-olds. They sat glued to the TV listening to the commentator giving them updates on what was occurring and asking me some
Smooth sailing with the next generation of yachts
The marine industry is undergoing major changes impacting the design, engineering, and manufacturing of all types of seagoing vessels. For instance, the class ranges of next-generation yachts and pleasure boats are growing, becoming more complex. Demand for more fuel-efficient models, longer range, and higher performance is increasing. The decisions on the material mix and associated
Tighter timeframes, tougher requirements, less stress? The argument for 1D-3D co-simulation
This blog post was co-written with Nick Amato, Manager of CFD Applications, Simcenter Engineering at Siemens Digital Industries Software. For today’s engineers, the ability to leverage multiple tools is essential to remaining competitive. Tightening regulations and increasing prototype costs mean that predictive analysis is more important now than ever before. In today’s environment of fast-paced

With autonomous technology on the rise, how can automakers face the transformation?
There is a clear trend in the market for driverless automotive systems: the direction is upwards. Autonomous vehicle (AVs) sales are expected to rise sharply after 2030, with an estimated $7T market worth by 2050. Autonomous technology is becoming a reality, but the automotive industry will need to undergo a radical transformation in product development to deliver
